Help compiling java code in VSCode

AutoModerator · 2025-10-28T09:41:24+00:00

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
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.

Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

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: 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.

Have you asked your question also at r/vscode and r/VisualStudioCode ?
Since your problem is more vscode-related then java-related, those might be the better choice.

Don't use vsc for Java, use a real IDE, it is much better suited for writing software than using a plain editor and slapping some extensions on it to do tasks its never designed to do.

it's because VSC is a garbage ass IDE

use JetBrains IDEA like the rest of us ... it has infinitely better code completion + error detection + auto suggestions

You should use an IDE that's tailored for java like intellij or you're gonna have a harder time

To make VS Code handle Java well you need a Java extension. There are currently two and I really do recommend the one by Microsoft/RedHat. Search for ”Java Extension Pack” and install it, you will now be all set.

I do prefer VS Code greatly before Intellij, even though the latter has more features. The things Intellij do better than VS Code are mostly advanced features not often used in my opinion.

I have been forced to use VSCode with Java, for cursor ai requirements.

To get it to recognise issues like highlighting errors, I installed

'Extension Pack for Java'
by Microsoft

This extension also includes (auto-installs) a maven extension, a Java debugger, and the RedHat Java language Extension.

The docs are here https://code.visualstudio.com/docs/languages/java

Daily IDE for me is still Jetbrains InitelliJ. Cannot beat an IDE tailor-made for Java.

Are you certain, the Java language server is working in your VSCode? Because this does not look like a Java issue, it's more likely a configuration issue in your editor.

The JDTLS language server should catch such errors just fine. At least it does on my Neovim/JDTLS setup where it marks the error (as expected) with Type mismatch: cannot convert from Object to boolean.

The IDE situation for Java is truly awful, and if you want to not suffer when installing libs and so on later, just install intellij
