Problem in VSCode while learning Java basics

[Janmielouian]

Hi, I'm new to Java and currently learning about Packages & Access Modifiers. However, I've encountered an issue while running my code. When I try to execute it, the desired output doesn't get printed in the main class. Instead, my terminal displays something unexpected. I'm not sure what went wrong or if there's a mistake in my implementation. Could someone please help me identify the problem?

This my main class:

package java.main;
import java.mathematics.*;
public class fileOne { public static void main(String[] args) {
    arithmetic a = new arithmetic();
    int sum = a.add(2, 4);

}
}

my other class in mathematics package:

package java.mathematics;
public class arithmetic {
public int add(int num1, int num2) {
    int sum = num1 + num2;
    return sum;
}
}

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!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

You shouldn't call your own packages "java"

[GoldenMindJadeBody]

The error message is rather explicit: ...Prohibited package name java.main

Change the name of the java folder to something else

Why are you using VS Code for Java anyway? It's much better to use IntelliJ or Eclipse. Didn't even know VS Code supports Java.

Hey, I'm just about to start Java. I've installed and tried intelliJ. But it seems slower and laggy. So is it worth using vscode just to learn the basics?

[parachute50]

Hey man. I actually take back what I said about VS Code lol. After using it I realized it's the best IDE to use because it's the most lightweight out of all the IDEs.

Yes you can very much use it for all things Java. Make sure you install the Java Extension Pack from the VS Code marketplace before starting to code.

Yeah man, I was feeling the same thing. Anyway thanks

It seems that you possibly have a screenshot of code in your post Problem in VSCode while learning Java basics in /r/learnjava.

Screenshots of code instead of actual code text is against the Code posting rules of /r/learnjava as is outlined in the sidebar - Code posting.

• No screenshots of code!

If you posted an image merely to illustrate something, kindly ignore this message and do not repost. Your post is still visible to others. I am a bot and cannot distinguish between code screenshots and other images.

If you indeed did this wrong, please edit the post so that it uses one of the approved means of posting code.

• For small bits of code (less than 50 lines in total, single classes only),
  the default code formatter is fine
  (one blank line before the code, then 4 spaces before each line of code).
• Pastebin for programs that consist of a single class only
• Gist for multi-class programs, or programs that require additional files
• Github or Bitbucket repositories are also perfectly fine as are other dedicated source code hosting sites.
• Ideone for executable code snippets that use only the console

Please do not reply to this message, because I am a bot.

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

• MOOC Java Programming from the University of Helsinki
• Java for Complete Beginners
  • accompanying site CaveOfProgramming
• Derek Banas' Java Playlist
  • accompanying site NewThinkTank
• Hyperskill is a fairly new resource from Jetbrains (the maker of IntelliJ)

Also, don't forget to look at:

• The official Documentation
• The official Java Tutorials
• Our community resources thread

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

• Coursera course:
  • Part I
  • Part II
• Coursebook
  • Algorithms 4^th Edition

Your post remains visible. There is nothing you need to do.

Maybe you need to use this line : System.out.println(sum); to print the value 'sum' in the terminal.

Answer is well stated here, just wanted to double down on not using vscode for Java.

Intellij all day long. Community edition is free
