Написать программу на Java без текстовых редакторов?

Программу на java можно создать, используя одну командную строку. (по крайней мере на windows, хз что там у других систем)

Познакомимся с некоторыми командами:

echo - команда для вывода текста. Она будет записывать код в файл;

javac - компилятор. Переведёт код в байт-код;

java - загрузчик приложений. Запускает код.

Открываем cmd. Пишем:

echo class CmdHi { public static void main(String[] args) { System.out.println("I am a good programmer!"); } } > CmdHi.java

Создастся файл CmdHi.java, внутрь запишется код, который при выполнении выведет строчку "I am a good programmer!".

Чтобы посмотреть содержимое файла, можно использовать команду more:

more CmdHi.java Вывод: class CmdHi { public static void main(String[] args) { System.out.println("I am a good programmer!"); } }

Далее программу надо скомпилировать:

javac CmdHi.java

После чего можем запустить код, указав скомпилированный класс:

java CmdHi

Результат:

I am a good programmer!

Скрин для наглядности

Кстати, с 11 версии джавы простейшие программы не требуют компиляции, поэтому сразу после echo можно сделать так

java Hi.java

Наблюдение: русские символы при выводе в командной строке могут не читаться

Hello!

This might be a weird question, but since you work in IT, do you use AI tools like ChatGPT or Claude a lot, or not at all? I’ve been learning programming for a few months, and honestly, it’s super hard. I’m definitely not a genius, so I use AI a lot to help me figure out what I’m doing and generate code.

The problem is that other students kind of judge and look down on people who use these tools, and it’s making me feel bad about it. Should I stop using AI altogether? I just don’t know how to manage without help or researching all the time.

If you have any tips, they'd really help me out 🙏

Thanks for reading this!

Hey anon! Well, the thing is that the IT industry in its entirety is pushing for AI integration as a whole into their products, so industry-wise it has become sort of inevitable. That being said, because we are still early into the adoption of AI I personally don't use it as I don't have much of a need for it in my current projects. However, Github Copilot is a tool that a lot of my colleagues like to use to assist with their code, and IDEs like IntelliJ have also begun to integrate AI coding assistance into their software. Some of my colleagues do use ChatGPT to ask very obscure and intricate questions about some topics, less to do with getting a direct answer and moreso to get a general idea of what they should be looking at which will segway into my next point. So code generation. The thing is, before the advent of ChatGPT, there already existed plenty of tools that generate boilerplate templates for code. As a software engineer, you don't want to be wasting time reinventing the wheel, so we are already accustomed to using tools to generate code. Where your work actually comes in is writing the logic that is very specific to the way that your project functions. The way I see ChatGPT is that it's a bit smarter than the general libraries and APIs we already use to generate code, but it still doesn't take the entire scope of your project into consideration. The point I am getting at here is that I don't necessarily think there is a problem in generating code, whether you are using AI or anything else, but the problem is do you understand what the code is doing, why it works, and how it will affect your project? Can you take what ChatGPT gives you and actually optimize it to the specifics of your project, or do you just inject it, see that it works, and go on your merry way without another thought as to why it worked? So, I would say, as a student, I would suggest trying not to use ChatGPT to generate code, because it defeats the purpose of learning code. Software engineering as a whole is tough! It is actually the nature of the beast that, at times, you will spend hours trying to solve a specific problem, and often times the solution at the end is to add one line in one very specific place which can feel anticlimactic after so much effort. However, what you get from all those hours of debugging, researching, and asking questions is a wealth of knowledge that you can add to your toolbox, and that is what is most important as a software developer. The IT landscape is rapidly changing; you might be expected to pick up a different programming language and different framework within weeks, you might suddenly be saddled with a new project you've never seen in your life, or you might suddenly have something new like AI thrown at you where you suddenly have to take it into consideration in your current work. You can only keep up with this sort of environment if you have a good understanding of programming fundamentals. So, try not to lean too much on things like ChatGPT because it will get you through today, but it will hurt you down the line (like in tech interviews, for example).

Common (Lisp) gaslighting

TLDR I am a fucking noob and I wasted a lot of time on Lisp.

Also Tumblr has terrible text markup.

Common Lisp has many implementations, but

More like many incompatible implementations - they may implement all, but have different ideas about non-standards like FFI, threads, and what not

Libraries like Bordeaux-Threads, CFFI, Closer-MOP actually tries to provide a baseline for ALL implementations, just look at all the #+ in the code - reading the libraries feels like reading how every implementation does things

When they say there's a lot of libraries, this is not what I have in mind - if standardising features across implementations is a library, then I have nothing much to say

If you are creating an application (not designing a library), the libs above are actually not helpful as they are another layer on top of the implementation itself

Other implementations are problematic

https://www.reddit.com/r/Common_Lisp/comments/15maush/clozure_cl_1122/

https://gitlab.com/gnu-clisp/clisp no Windows binary release since 2010, developer refuses to support MingW 64bit, GPL program

On Lispworks

Lispworks has GUI, tree shaker, ability to create shared libraries, and good support, but..

It costs way too much - USD 3,000 for 64-bit Windows, or about MYR 14,000. Daylight robbery. If I want a great GUI designer, there is JFormDesigner, one time purchase of USD 179. Intellij reaches price parity at 29 years.. the entire Jetbrains suite reaches price parity at 17 years..

Lispworks have Hobbyist starting at USD 750.. but anyone trying to justify that other hobbies also cost this much is missing a huge point - most hobby allows them to resell their stuffs, and you can even do commercial stuffs with it. I am pretty sure that you cannot sell back your license, and can only upgrade, which is paying another USD 2250..

Whereas Jetbrains has Intellij and PyCharm community edition - awesome products, free, and can be used for commercial purposes

All Lisp follows a standard, so it is portable/stable/etc

More like dead. No one bothers to standardise threads, C ffi, etc

The language has a lot of unnecessary nesting thanks to let/flet and friends - I can also use https://quickdocs.org/serapeum and use the macro local, but this library pulls 19 libraries, one of them Slime, which is used for .. I actually don't know why it is needed, isn't Slime used for interacting with Emacs???

https://portability.cl/ doesn't seem portable to me

Library situation is still bad

No implementation comes with GUI. Quite bad considering how having many implementations is considered a good thing (actually there are ABCL but that's cheating)

I am looking for https://docs.python.org/3/library/cmd.html, I see that https://github.com/vindarel/replic is a good library, and is MIT licensed. But it uses GNU Readline, which is definitely GPL. replic depends on cl-readline, which is GPL. So.. isn't replic supposed to be GPL because of its dependency on GNU Readline? The author owns the code for replic and cl-readline, but not GNU Readline

Out of the box, almost all the implementations doesn't come with batteries. (Racket included, as a user say it comes with a retrofittable fusion battery pack)

When I think of batteries included, I think of this.

I am looking for game development

I see xelf, it asks for SDL.dll, and a bunch of other dlls, which I have to supply. SDL1 last update was around 2013

This is one where "stable" or "will work for decades" fails badly

I see SDL2, it asks for SDL2.dll

I see raylib, it wants to compile C stuffs (which I did not install). Why??

I see Trial, I see the docs, I feel dumb

On the other hand

pip install pygame-ce, look at docs, viola

pip install raylib, copy starter code, viola

Download gdx-liftoff, generate project, open in Intellij, viola

The docs for these game libs are so easy to read, and all of them includes the DLLs required

Why don't Common Lisp stuffs include the DLLs? You expect me to put it in the Systems folder? Expect me to use Linux and apt install sdl/whatever? The idea that I "use Linux for easy development and then compile using Wine" is insane

And best practices..

https://google.github.io/styleguide/lispguide.xml

I might as well use C++ and read http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines, even Lisps programs eventually need to interface C stuffs, and Python can use nanobind with great effect

As to why I say C++ when talking about interfacing C, it is because these days, the world is built in C++

Please don’t assume Lisp is only useful for Animation and Graphics, AI, Bio-informatics, B2B and Ecommerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list. – Kent Pitman

Where?? Please show me where it is. Otherwise it feels like gas lighting.
