'How to use java .class file in Visual Studio Code?

I'm currently studying a Java course, and one of the assignments requires me to use (import) a class inside a .class file.

I'm currently using Visual Studio Code, and I can't seem to find a way to import the class into my Java code.

We are not given the .java code. From what I can tell, Visual Studio Code does not support the use of .class files.

Solution 1:[1]

as I know, intellij idea can decompile the .class file depends on the build in decompile plugin, while the extension named 'Java Decompiler' in vscode marketplace works a little complex. maybe you can take a try, use the 'Java Decompiler' extension or take a look in the intellij idea.

The easiest way is to have both classes in the same directory, like in this example. Say you have class A

public class A {
    public int fun() {
        return 0;
    }
}

to use class A from class B in the same directory, you just declare a type A in your B

class B {
    public static void main(String[] args) {
        A a = new A();
        int i = a.fun();
        System.out.println(i);
    }
}

this will print 0.

This works because both classes are in the same directory, and class A is declared public.

Being in the same directory, with no package declaration, means that both classes are in the default package, this is the easiest case.
