LOL I can imagine for vampire au Lando starting to third wheel Carcar and so even though turning Franco is a complete accident he can’t feel too guilty bc he uses it as an excuse to hang around someone else, and somehow he learns more about vampirism lore through a human grad student than he’s learned in his whole life (he’s lived a long time, lots of info to absorb). Then also, if you don’t mind my ask, what do they all do for jobs/how do they get money and would Franco keep studying ?

HELP this is so cute. ok. norpinto-frando vampire au for those who aren't up to speed...

Lando starting to third wheel Carcar and so even though turning Franco is a complete accident, [Lando] can’t feel too guilty bc he uses it as an excuse to hang around someone else -> screaming cus, absolutely. random associated headcanons for this... i'll rewind a bit:

carlos is the oldest vampire, like, moorish/medieval era. he met lando while they were both at a masquerade ball in the early 1600s and smelled each other right away (carlos like wood and ink, lando like gas lamps and wet stone).

lando is an tudor era vampire. like he actually knew shakespeare and said he was one of the best viral marketers of the era

oscar was turned in the early days of the australian penal colony, he's like first or second generation white australian but he refuses to be called british. he moved in to the house because the rent was cheap and he doesn't feel the need to live extravagantly -- even though he, too, is $$ loaded $$

oscar didn't move in until about two decades ago - very short by vampire standards, to them it feels like yesterday - but carlos and oscar are basically They Were Roommates atp even though they squabble con-stant-ly

their neighbours think they are a new age-y polyam group but because the people who live opposite them are students, nobody ever hangs around longer than a year to remember them or dig deeper

so franco definitely brings a fun funky fresh dynamic

he learns more about vampirism lore through a human grad student than he’s learned in his whole life (he’s lived a long time, lots of info to absorb) -> things that baby vamp!franco teaches lando include

tiktok trends, like how to make ur teeth comically large in photos. lando finds this hilarious

how to use venmo

creating a roster on google docs for who needs to do what house chores

jailbreaking an apple watch so it doesn't read their pulses (they don't have any), but it will remind them of the moon phases and when they might be extra hungry to feed

at one point franco actually puts his academic skills to use and helps lando hunt down some of his family tree, because since lando was turned and it's been so long, he doesn't remember much about them : ( so one of franco's little gifts to lando is helping him trace his heritage

what do they all do for jobs/how do they get money and would Franco keep studying ? -> i love how practical-minded you are. um well let's say this fictional supernatural creatures' market mostly runs on barter trades and goodwill agreements. the entire house sometimes just gets lazy tbh so lando or carlos will just dig into one of the old chests of random shit and pull out an antique and go: "do we think this is worth anything?" then they take it to an antiques dealer who is also a mage (alex albon) and there is a 1 in 25 chance that the antique is actually is worth something, so that bankrolls them for another half a year or whatever.

carlos makes a lot of noise about being "an art dealer" just because he sold a goya painting to a museum once.

oscar is a man of industry, of the "newer" world (australia) etc etc so he spent the 80s and 90s learning C++ and Java and Python so he legit just codes for a living. or when he feels like it. oscar has helped launch at least a dozen startups under various pseudonyms and one of them is even a blue chip company by now. he doesn't do it for money tho. he just does it cus he likes a challenge, and otherwise fights with carlos too much. when he isn't coding he likes to tinker and fix things just for fun. like, he legit knows how to fix a boiler and stuff. his familiar is definitely a grumpy orange neighbourhood cat.

franco keeps studying!! he is such a nerd that he's like "i can totally learn everything about anything now, and i could in theory do like 20 masters degrees, and nobody can stop me"!! then lando is like, "well you might get bored of it after a while or burn out". but franco insists he will not. in fact with his enhanced neurological abilities he goes on an academic bender trying to fast forward through an entire harvard's undergrad degree's worth of material in a week, and he ends up faceplanting on his desk. and then poor lando has to go and find a fresh chicken or something to kill and revive franco 'cus franco wore himself out too fast being a bb vampire with accelerated mind powers.

franco promises never to do that again (but of course he will continue to do it once in a while, and everyone still looks after him in his lil study hangovers because he is so very nice. also he taught them how to use venmo.)

and. one time. franco is like. "i can't find this rare sonnet do you know what library i could maybe locate it in" and lando is like "wait i know that one" and pulls out an honest to god original copy that he at some point got laminated in the early 80s. and franco is like. "um i think this should be in a museum??" and lando is like "yeah but i gave them a copy of this, cus i spilled ink on the corner of this in 1603 after a really good night out" and franco is like "???? ok ????"

then lando swans off to moodily stare at the moon or some shit.

What advice could you give someone learning Java as a first language?

The best advice I can give to new programmers is:

Programming utilizes different problem solving skills that what you are likely used to. It will likely be overwhelming. This normal. It will get better as you grow more familiar with programming and learn new techniques, algorithms and best practices. Remember that this is Skill, and you improve your skill through practice.

DO NOT USE CHATGPT OR OTHER AI TOOLS TO START. If all you're doing is pasting what ChatGPT spits out then you are not really learning. It is more important to understand why you did something over getting a correct answer. You have to be able to defend your code and though process in a corporate setting if you are looking to pursue a career in software. (Think about this like showing your work in math class). When I took AP Comp Sci many moons ago, we used JGrasp a Java editor which is basically fancy notepad with a great debugger. No auto-complete, no code generation, not even spellchecking. When learning a new language you should learning the language, not the tools.

There are multiple correct answers any given problem. Programming is not like math where there is only 1 right answer for the problem. Solving the same problem in multiple ways is great way to expand your toolbox.

Some Java specific things:

If you're just starting, there is lots of AP Comp Sci course material out there. (books, quizzes, youtube, etc). You can surely find one that speaks to you.

If you have the language basics down make small graphical games like checkers, chess, etc in Swing. Its a great way to learn while doing something fun.

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.
