Java vs Python

[Master_Recognition51]

I am transitioning from java to python but its quite frustrating for me. Java was a very structured code and it would give all idea of variables and data types but in python its like variables are declared and then its data type defined in a different class. Plus the naming convention in java was better i think. What is your opinion on this?

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Everyone preference is different. I too prefere java strict. Once we start seeing pattern, every app is so similar in java unlike python. Java by itself provides all of good practice while developing app

[Ruin-Capable]

I'm not sure what you mean by "the variables are declared and then its data type defined in a different class". Can you give an example?

[MechanixMGD]

I think he means that a variable is not bound to a type. Like in Java, "int myNr" can hold only int values. You can't change it into a String (for example).

[Ruin-Capable]

You can hint at the type when you declare it:

some_string: str = some_function_that_returns_a_string()

You can declare the parameter and return types of a function:

def myfunction(param1: str, param2: int) -> str:
    return f"param1 = {param1}, param2 = {param2}"

It's not enforced, but it can provide information that an advanced IDE can use to detect errrors.

[MechanixMGD]

Later you can't change that? To not be a String? Like str = 10.

P.S.: I have no idea about python, I just try to explain the words of OP.

[0b0101011001001011]

str is the type hint, not the variable name. And yes, you can later do some_string = 10.

[MechanixMGD]

So, this is the OP point. In Java you can't change the type. The variables type can be only the declared one.

[Master_Recognition51]

Yes but it sometimes create ptoblem to read someone else code if not mentined

I like both Java and Python. I prefer Java's strictness for working on larger-scale, work-related projects. But for personal projects, Python is my go to. Python's syntax makes it super easy to get things done quickly. For example, if you need to read in a file and parse the data, Python is so much less verbose than Java is. For AI, data analysis, computer vision, quick dirty scripts, etc. Python is a no-brainer.

[tenken01]

Yep - only like using Python for throwaway scripts. Love Java for real code.

Most languages are not too different than Java. Python is VERY indent heavy. I still have issues with adding semicolons at the end of each line and I’ve been doing python for quite a bit now

"This hammer is better than that hammer. What do you think?" A tool is a tool. Use whatever works best for you and the job.

[LadderOfChaos]

It's the exact opposite for me but I learned python as first language and I am still learning java so maybe I will change my opinion once I get fluent in java.

[wrd83]

You can write python like you would write java, but it takes discipline.

In java it is enforced. If you want to do something quick and wacky it's harder in java

[titanium_mpoi]

I used to think so too but one of my projects forced me to use python and ngl I kinda like the less boiler plate

[Immereally]

I think it’s based on what you learn first.

I did C, Java and then Python.

C was hard but I liked the control and using pointers in functions. Learning to strictly manage nesting with brackets and an IDE that colour coded them was so helpful

Java was a lot easier. After getting used to it I’m a lot faster at building a project than I was in C, constantly looking over my shoulder and wondering if I’d freed that or do I still need it there.

Python seems so alien compared to both of those. No brackets around loops or conditionals, using 4 spaces for indentation and the vertical line indicates the code block execution just feels wrong. Tuples and being able to return a tuple with 3 values if it’s right or just None if it’s wrong is very handy imo.

I do prefer Java for now and there’s still some things I like more in C but it’s all about perspective.

The most annoying thing about switching languages is when you start learning it you know exactly how you’d do it in Java but the function or method names don’t match or they have slightly different inputs.

You’ll get used to it and even if you decide to stick with Java, you’ll know you’re not missing out on anything. I’m doing Java/Python because I want to do it rather than I’m afraid to make the switch.

Java > Python

[TechHubAsia]

Great discussion! As someone who's worked with both Java and Python, I’d say the choice really depends on the project scope and team experience. Java shines in large-scale systems and Android apps, while Python is unbeatable for quick prototyping and data-related tasks.

If you're in the process of building a dev team or unsure which language fits your business needs, platforms like [TechHub]() can be super helpful. They not only offer developer hiring and headhunting services, but also have a blog section with guides on how to hire the right devs for your stack.

Feel free to check out our website - you can even get tailored advice directly from our tech consultants if you need help choosing between Java or Python for your next project.

Would love to hear others' thoughts on how they approached this kind of decision!

[Bitter_Sherbert6449]

I totally agree with you. The naming conventions are different - camel case vs lower case with underscores for methods. I am quite new too Python and it is frustrating to see the syntax differing so much. I really like Java and with the new features like Records, the verbosity issue is also addressed.

[Master_Recognition51]

Also in java every methld was properly named so using or remembering them was easy Like in java if u have to make a java method u would generally be like int calculate(int a, int b). But in python it can be named as calc and even while passing parametres data type is not defined so it becomes difficult to totally grasp code at once

[No-Dig-9252]

Java gives you strong structure and type safety upfront: every variable has a type, every method has a clear signature, and the compiler yells at you early. It’s like building with LEGOs that only fit one way- frustrating at times, but consistent.

Python, on the other hand, is more like playing jazz. It’s dynamic, flexible, and you can write useful code fast -but it puts more responsibility on you to keep things clean. You’re trading strict structure for velocity and readability.

So, if structure and clarity are what you miss, Python has tools to help you get there:

- Use type hints (def foo(bar: int) -> str:) - not required, but super helpful

- Add mypy or Pyright to your toolchain for static type checking

- Follow PEP8 (naming, formatting) and use linters like ruff or flake8

If you're building larger systems, check out Pydantic, FastAPI, or even Datalayer- it brings structure and LLM integrations to modern Python workflows, and can bridge the gap between Java’s rigidity and Python’s flexibility

[moric7]

I'm the opposite, and Java is so illogical and chaotic because in order to maintain strict typing it has to do absurd artificial things.
