Coding Brushup: Java Exception Handling Best Practices

In this coding brushup session, we focus on one of the most critical aspects of writing reliable and robust Java applications — Java exception handling. Exception handling in Java is not just about catching errors; it’s about managing program flow, providing meaningful feedback, and ensuring your application remains stable and maintainable under unexpected conditions. This article outlines the most effective Java best practices course for handling exceptions, ensuring your skills are current and refined.

Why Exception Handling Matters in Java

Java exception handling is a mechanism that allows developers to manage runtime errors in a graceful and predictable manner. Rather than crashing the application or producing undesired output, exceptions help developers identify problems, apply fixes, and even recover from faults during execution.

As part of any serious coding brushup, understanding Java best practices in exception handling is essential for writing quality, production-ready code. Exception handling not only improves the robustness of the program but also enhances readability, maintainability, and debugging efficiency.

1. Always Catch Specific Exceptions

A fundamental rule in Java exception handling best practices is to catch the most specific exception possible. Catching generic exceptions such as Exception or Throwable should be avoided unless absolutely necessary. Specific exceptions provide more control and clarity over error management.

Catching only relevant exceptions ensures that you’re not inadvertently masking programming errors or swallowing unrelated problems. This promotes more accurate exception tracking and error resolution, which is a core component of professional Java development.

2. Never Swallow Exceptions Silently

One of the most common anti-patterns in Java exception handling is swallowing exceptions without any feedback. Empty catch blocks suppress errors silently, making it difficult to trace and debug problems when they arise. In a good Java coding brushup, it’s vital to emphasize that every caught exception must be logged, re-thrown, or otherwise acknowledged.

Swallowing exceptions hides potential issues and breaks the natural flow of Java best practices. Even when you choose not to halt the application, logging the exception is a must for long-term code health.

3. Use Finally Blocks for Cleanup

The finally block is a staple in Java exception handling. It guarantees that a particular section of code will execute, regardless of whether an exception is thrown or not. This is particularly useful for cleaning up resources like file handles, sockets, and database connections.

Using finally correctly ensures your application does not suffer from resource leaks or dangling operations. This is a vital point in any coding brushup since failing to clean up properly can lead to memory bloat or degraded system performance.

4. Prefer Try-With-Resources for Auto-Closeable Resources

Since Java 7, the try-with-resources statement is the recommended approach to handling resource management. This feature simplifies code and automatically closes resources that implement the AutoCloseable interface.

Using try-with-resources eliminates the need for verbose finally blocks and helps reduce boilerplate code, aligning with modern Java best practices. It’s an essential part of updating your skills in any Java coding brushup session.

5. Create Custom Exceptions Where Necessary

In many scenarios, predefined Java exceptions may not clearly describe the domain-specific problem your application is encountering. In such cases, it is a Java best practice to create custom exception classes.

Custom exceptions improve the semantic clarity of your code and allow for cleaner exception hierarchies. During a coding brushup, it’s crucial to learn how to define and use custom exceptions effectively to make your application self-documenting and easier to debug.

6. Log Exceptions with Proper Detail

Logging exceptions is a key practice in professional Java development. It’s not enough to print stack traces to the console; structured logging using tools like Log4j or SLF4J is far more effective.

Logs should include the exception type, message, and ideally, the stack trace. This level of detail ensures that you can trace the origin of errors and monitor system behavior efficiently. Logging is a routine yet vital aspect of any Java coding brushup, especially for those transitioning into production-level code.

7. Avoid Using Exceptions for Flow Control

Exceptions are meant to handle abnormal conditions, not for standard control flow. Using exceptions to implement conditional logic is an anti-pattern and violates Java best practices.

This approach not only reduces performance due to the overhead of exception handling but also makes code harder to understand. Instead, validate input and use regular control structures for predictable logic. This is a critical distinction in any thorough Java exception handling brushup.

8. Document Exceptions Clearly

Every method that throws exceptions should document them properly using Javadoc comments. This helps other developers understand what exceptions they might need to handle when calling your method.

This practice aligns with writing self-explanatory code and contributes to better collaboration in team environments. Any seasoned coding brushup will stress the importance of documenting thrown exceptions, especially in public APIs or library code.

9. Use Exception Chaining for Better Context

Exception chaining allows developers to pass the original exception to a new exception when rethrowing. This helps preserve the original error stack and provides additional context, which is essential for effective debugging.

Following this practice enables more meaningful and layered error messages, supporting a more holistic understanding of problems during runtime. This nuanced technique is an advanced topic often emphasized in senior-level Java coding brushup sessions.

10. Rethrow Only When Needed

Sometimes, you may need to rethrow an exception after logging or wrapping it. It’s important to do so judiciously, ensuring you’re not duplicating logs or losing stack trace information.

Blindly rethrowing exceptions can clutter logs and confuse the root cause of issues. Instead, when rethrowing, ensure that the context of the exception is either preserved or enhanced. This habit aligns closely with Java best practices and is a mark of mature exception handling.

Conclusion

Exception handling is more than just writing try-catch blocks — it’s about writing intelligent, predictable, and resilient code. In this coding brushup on Java exception handling best practices, we’ve covered essential concepts such as catching specific exceptions, avoiding silent failures, logging effectively, and using modern Java features like try-with-resources.

As a Java developer, refining your exception handling strategy will not only reduce bugs but also improve your codebase’s clarity and maintainability. Make these best practices a consistent part of your Java coding brushup routine to elevate your development skills to the next level.

Because of its adaptability and simplicity, Python has grown to be among the most widely used programming languages. Applications for it include everything from machine learning and scientific computing to web development and data analysis. It's essential to write code that is not only functional but also organized and effective as a Python developer.briefly describe the popularity of Python and some of its uses in different fields.  Mention how crucial it is to create maintainable, effective, and clear Python code.

1.Create a Developmental Environment That Is Productive:

Picking the Best IDE

Python development cannot be successful without an Integrated Development Environment (IDE). IDEs include tools for debugging as well as code completion and syntax highlighting. PyCharm, Visual Studio Code, and Jupyter Notebook are popular options. Depending on your personal preferences,

.

2. Follow Python Coding Standards:

PEP 8 and Consistent Formatting

PEP 8, the Python Enhancement Proposal for code formatting, outlines conventions that improve code readability and maintainability. Following PEP 8 ensures consistent style across projects. Additionally, use descriptive variable and function names and include comments to make your code self-explanatory.

3. Make Your Python Code Better:

Knowledge of Code Optimization

Making your code run more quickly without sacrificing clarity is known as code optimization. Performance is improved by using methods like list comprehensions that decrease the amount of loops. Global variables should not be used as they may cause unexpected behavior. Use built-in functions to speed up execution and make code simpler. The performance bottlenecks in your code can be found using profiling tools.

4. Leverage Python Libraries:

Expediting Development with Libraries

Python's extensive ecosystem offers numerous third-party libraries that provide pre-built solutions for common tasks. Libraries like NumPy are designed for numerical computations, Pandas for data manipulation, and Requests for making HTTP requests. Installing libraries using package managers like pip ensures easy integration into your projects

.

5. Efficient Project Organization:

Scalable and Maintainable Projects

Virtual environments are essential for isolating project-specific dependencies, preventing conflicts between packages. Organize your projects by creating a well-defined directory structure. Use the "src" directory to separate source code from other resources. This organization promotes maintainability and makes it easier for collaborators to understand your project's structure.

6. Effective Debugging Techniques:

Identifying and Fixing Bugs

Debugging is a critical skill for any developer. Common sources of bugs include syntax errors, logical mistakes, and unexpected input. Print statements and logging are simple yet effective debugging tools. Integrated IDE debuggers enable setting breakpoints, inspecting variables, and stepping through code. Handle exceptions gracefully with try-except blocks to prevent crashes.

7. Stay Updated with Python Trends:

Continuous Learning and Growth

Amateur Translation Programs

So I had a lot of imaginative and informative responses to my post about looking for an amateur translation program -- something where I could load in a foreign language and it would insert a box where I could add a translation every-other-line. The idea was that this way I could practice translation with more advanced texts, and texts I chose, and thus move away from Duolingo, which at this point is good for drilling and daily practice but not for more advanced learning.

I didn't find precisely what was needed but I did get some inspiration for further explanation, and I also learned that adding the term "glossing" (thank you @thewalrus-said) into my searches helped a great deal in terms of weeding out programs that were either "Let this AI translate for you" or just endless promotional links for Babbel and Duolingo and such. I thought I'd collect up the suggestions and post them here; at the end I'm including my best swing at designing what I wanted, and why it doesn't work yet.

Suggestion one, from many people, was various ways to generate a page that is simply fixed Italian text with space underneath each line to add in a translation. This is pretty simple as a process and there are sites that will do it for you, such as this one that @ame-kage suggested. However, most of these don't allow for movement in the Italian text, and many produce a PDF which you would need to print out in order to write on unless you're willing to open it in Acrobat (and deal with Acrobat). A good solution for some but not what I'm looking for purely because I'm trying to make this super frictionless so that (knowing myself as I do) I will actually do it.

I did find this version interesting, suggested by @drivemetogeek: Have one word doc saved as your "template" doc and set the line spacing as 2.0 or higher. Select your text from source and paste it into the template doc as text-only. Ctrl a, ctrl c to select all and copy, then open a new document and "paste special" as picture. Right click and set the "wrap text" as behind text. Now you have a document where you can, basically, type over the existing text because it's the background of the page. This seems like the most frictionless version, because you could set up a bunch of them ahead of time. If you wanted to move between desktop and mobile, however, you'd need to ensure that the pasted image was fairly narrow so that you don't have to sideways-scroll.

Relatedly, people suggested generating a document that is simply the Italian text with empty space beneath it for typing in of the translation. This can be done either semi-automated, using a macro or a language like Python, or find-and-replace on, say, the stops at the ends of sentences. It basically outputs the same as above but with a more digitally accessible format, without any more effort than above. If you were to do this in Google Sheets you could also fix the column width so that it didn't do anything weird when you opened it on your phone. But it is still very friction-y, and does not allow for easy shifting of the Italian as needed. There's high probability of the translation breaking weirdly across the page. Still a top option in terms of simplicity and access.

@smokeandholograms suggested another variation illustrated here where essentially you're converting the text to a series of tables, with each paragraph a row, and an empty cell next to it for the translation. I might play around more with this one eventually, since I think I could possibly make it a three-column and put the Italian in one, the translation in the next, and the auto-translate to let me know where I might be slipping in the third. (Not that I trust auto-translate but comparing a hand translation to an auto translation can be useful in terms of working out when I've messed up the way a tense or mood is read. I tend to read indirect verbs as automatically imperative because I'm a weirdo.)

@wynjara linked to an add-in for Word specifically designed for translators, known as TransTools; this appears to employ a macro to do the same thing, though it does have a format where you can place the translation next to each sentence directly rather than in a separate cell. The full suite of tools is only $45 which is reasonable for my budget, but for what I need I think I could also just create the macro.

Using LaTeX as a tool specially designed for glossing was an option on offer, but I don't know enough about LaTeX to figure out the pros of this one, which is in itself the major con -- there's a learning curve that I think varies widely by person but for me is unfortunately a wall. It came out of a discussion on Reddit about trying to find something like what I want; also in that discussion is a link to a code generator that allows you to…do something…to the initial language, but it's not entirely clear to me (I'm sure it's clear to people who understand coding) what you would then do with it that would allow it to be output in the way I'm hoping for. Like, I could turn a paragraph of text into HTML, I understand that far, but any Italian I find is already on a website.

Moving more into apps that might work, Redditors on the LaTeX discussion suggested SIL Fieldworks, which is a professional language tech tool. Fieldworks isn't a program I'd previously encountered but much as with the ones I had, it looks like the learning curve is fairly steep and it is definitely overkill generally for what I need, though it might also harbor within it the thing I want. It is free, so I may download and play around with it.

@brightwanderer suggested using note-taking or "whiteboard" apps such as Freeform or Nebo; these are generally a kind of "infinite canvas" in which you can drop objects, text boxes, or handwriting. I don't know that Freeform would be measurably different to just using Word and a macro, since I'd still have to input/format all the text and then be stuck with the same "fixed text" setup -- and it's also iOS only -- but for some folks it might be more helpful. Nebo is a similar infinite-canvas with unfortunately the same issues, though on the plus it's available for Android, which is where most of my mobile property resides.

@bloodbright suggested that I was looking for a CAT tool, a professional translation tool mainly used by translators working in the field. This was a concept I'd encountered, but I hadn't found a good starting place. They suggested Smartcat and OmegaT. Smartcat bills itself as an AI translation platform and is HARD pushing the "don't translate it yourself, hire a translator or let AI do it" angle, so it's difficult to tell what it offers in terms of actual tools for translators, and it's also cagey about pricing, so I can't really evaluate it. OmegaT is free and gives off big "some weirdo homebrewed this in their basement" vibe (which I am here for) but I also recognized it from screengrabs that were the reason I veered away from professional-grade software: it looked too complex. Realistically, the major downside of OmegaT is that I don't think I can put it on my phone. One thing I did find interesting is that once you translate a portion of the text, the original language goes away, though I assume you can turn that off if needed. I do kind of like that because it means my distractable brain is looking at Less Stuff.

So where did I end up?

Well, it looked like I was going to have to try a homebrew myself. I had the idea of trying some of the initial suggestions but in reverse -- designing a document where every other line was a single-cell table fixed to the page. You could paste in the Italian, which would wrap around the cells, and then enter the English in the cells.

You can fix a table in place in Google Docs -- you click on the table, then under Table > Style select Wrap Text, Both Sides, and Fix On Page. Getting the whole page set up is a little labor intensive but once you did that, you could just save it as a template and make a duplicate of it each time. And this actually works….on desktop.

Unfortunately, if you open it in the mobile Docs app, the app can't handle the fixed tables and automatically moves them all to after the text that's been pasted in. I tried redesigning it so that it's a table within a table -- one for the Italian, then within that a series of them for the English -- but when you nest a table in Google Docs, it doesn't let you fix the second table in place. And you are also still dealing with the wrap issue, although you can resize the page and add a large right-hand margin as a kludge of a fix for that.

You can build this same kind of document in Word, so I tried building one in Word and then uploading it to Drive, but when you open the Word file in Docs (or in Microsoft Word for Android), it still strips the fixed positioning -- there's just some functionality missing from both apps that doesn't allow them to handle fixed-position tables.

So, the design is sound, just not the final execution. If I could program an app, I could probably remedy the issues with it -- it's simply a series of text boxes nested inside one another with different formatting. I would imagine that's relatively basic to set up, although given that neither Docs nor Word can handle fixed tables in mobile, perhaps I've stumbled on a much bigger problem that everyone is ignoring because nobody actually needs or wants fixed tables in mobile. :D

Experimentation is ongoing, anyway. I might simply have to resign myself to the fact that my translation study is going to have to be in front of a computer, which might be for the best anyway when I inevitably want to compare my translation to an auto-translate to see where I might have read something wrong.

LAB PREP + PRACTICALS WEEK [1st Jan - 9th Jan]

a quick summary!

happy belated new YEARRRR (we're six weeks into the new year time is so slippery and for what T_T)

I finished like 10 pens writing assignments and record books this week and didn't study at all so I failed an html mock assessment thing lol but its cool

the events of each lab: math: it was python, but they taught us jack-shit so I ended up memorizing the programs 2 hours before the lab, and passed with flying colours 👍 there was no viva thank god c lang: they gave us 10 programs to study and I'd actually pre-prepared for this because our professor tricked us into thinking it was a week before. I spent like 20 hours straight learning these programs a week ago and it didn't even happen T_T it went fking amazing though, and so did viva!! I got full marks!! :D physics: studied the experiment write-ups the night before and kind of forgot some of it because the experiment I ended up getting had some heavy content - there were so many tables and so many graphs T_T - I persevered though and breezed through the actual experiment conduction because I'd been teaching it to my lab-mates the past week! I thought my viva went disastrously BUT I passed with a 0.4 deduction only!!

my uni's tea is the best tea 👍

Hi! You mentioned there are online tutorials/sites for learning Comp Sci and OSINT - any recommendations? Thanks!

Hi! You got lucky that today is the day I check my inbox lol. So. For comp-sci: - CS50X from Harvard is a public avaiable course on youtube I'd 100% recommend. These are the undedited (so far) lectures of 2024: https://www.youtube.com/watch?v=3LPJfIKxwWc&list=PLhQjrBD2T381WAHyx1pq-sBfykqMBI7V4&ab_channel=CS50

This gives you all the basics you need to understand how coding and pcs in general works. (I had comp sci in my university course)

- Freecodecamp is a website full of FREE tutorials on several programming language. Advice: learn python. You will understand later on.

- The rest really depends on what you actually want to learn and why - each programming language has its own purpose and application. OSINT: -There is this full course: https://www.youtube.com/watch?v=qwA6MmbeGNo&t=205s&ab_channel=TheCyberMentor (But you can find more on youtube.) - Bellingcat's resources: https://www.bellingcat.com/category/resources/ -IntelTecniques: https://inteltechniques.com/ - Osint Newesletter: https://osintnewsletter.com/

But here is the catcher: if you plan to do osint it heavily depends on where you live. I'm in Europe, so it means I'm under GDPR, therefore I must abid to stricter regulations than a US OSINT analyst. A lot of data that might be considered public domain in the US(big one: conviction records) are not in europe, and you won't be able to access it unless you are a registered private investigator at least (but in my case it's rare that I go after people, that's not a part of any task I might encounter at work). Not only that, but a lot of the avaiable tools are designed to work only with specific countries in mind for various reasons and there is a big bias on US-based investigations. If youre' not in the US I recommend you reach out to your local OSINT or cybersecurity professionals association, they usually have resources and specific information, a lot of times for free. Also keep in mind: OSINT has a lot of different applications and it depends on what you're doing with it. Journalists might work more with satellites and images (a thing I know nothing about), debunkers will definitely understand social media more, if you do business intelligence you will look more at news sites, trademarks and deposits and so on to reach your conclusion. You did your course... Now what? I recommend getting on CTFs, like tracelabs that I've linked above, but there many of them (osint dojo for example) or Kase Scenarios. These are safe environments to practice on (except for tracelabs since it deal with actual cases of missing people and it can lead to... not so good leads, allow me to leave it there) You should also understand how intelligence (as the discipline) works. There are several resources, but my favourite is definitely Psychology of Intelligence Analysis. It's a series of declassified training documents from CIA analyst Richard Bauer, that was based on Daniel Kahneman (yes, the "thinking fast and slow" author, and I also do recommend this book) research on euristics. Intelligence is fundamental because OSINT might be helpful to gather the data, but the data then needs to be processed, analysed and you also need to get a conclusion from that analysis. Studying intelligence will help you avoid a lot of pitfalls that happens when you do an investigation, such as not understanding when you know enough, if you're being a victim of your own bias, if you're missing something or if you're going with the right approach. But I have to admit that the best of training I've received so far is from my local OSINT association because I've been able to train with people that work(ed) in the military, get their advice and have a deep understand of the work itself (and the reason why I have decided to actually make cyber threat intelligence my job, even if I work for a private company and I have no interest in working for the government). And yes ethics is a big thing for the OSINT community.

I hope this is helpful enough!

Hot take : books have too many words

Now that I have your attention, I'm talking about instructional books. Non-fiction books with the purpose of teaching a skill.

Representative example : Automate The Boring Stuff With Python by Al Sweigart. Ostensibly, this is an application-(pun intended)-forward approach to teaching/learning how to program.

Guess on what page, excluding indexes, excluding the forward, you're asked to actually write a single program.

Page 56. Question 9 of the practice questions on the final page of chapter two. And it's a simple if, elif, else decision tree. I bought this book used and the previous owner stopped bookmarking and highlighting on page 41. They didn't write a single line of code themselves.

This isn't a problem unique to this book, it's a criticism I have of most books like this. My criticism of this book is in how similar it is to every other programming book for beginners. But this isn't just true of this domain, it's true of music, it's true of drawing, it's true of painting, it's true of creative writing, second languages, any skill you can learn. I've spent the last year and a half just trying to learn how to do new things as an adult and it's been more and more of this schlock.

I am a firm and committed believer in books, and I think digital learning tools are at best a poor substitute in a pinch. But this is not the way.

Fact of the matter is that humans are really bad at high-level concepts. We are bad at making them, we are bad at communicating them, and we are bad at learning them and drawing conclusions from them. So many highly educated people I know in my field are dumb as rocks because of this.

Learning a new skill happens from repetition. It's a training regimen that involves frequent direct instruction, but it should be at least 50% training.

Imagine if I were your personal trainer (gym) and our first week I just spent every day talking about proper form, nutrition, muscle groups, etc., without you actually doing anything. It may or may not be useful information but you won't have retained much and you wouldn't have grown at all in your fitness!

Gotta put my money where my mouth is and write books...
