Using the example from the previous lesson doesn't work

Question about the task

How do I choose the right one?

Java Multithreading, Level 3, Lesson 6

Under discussion

In the previous lesson, they have the line:

Zoo.Mouse mouse = new Zoo.Mouse();

Why isn't the solution:

obj = new Solution.TEST();

This won't compile, it says it doesn't know what TEST is.

Try inputting the code into the IDE on codegym instead of using intellij

should work that way, even new TEST(); should work as main is inside the Solution class. So without the entire code it's hard to guess where the problem might be. Have you maybe changed given code?

I haven't changed anything else. Here is the code I have:

public class Solution
{
    public static final String TEST = "test";

    public static class TEST
    {
        @Override
        public String toString()
        {
            return "test class";
        }
    }

    static Object obj;

    public static void main(String[] args)
    {
        obj = new Solution.TEST();
        System.out.println(obj);
    }
}

Intellij underlines Solution.TEST in red, saying "can't resolve symbol TEST".

weird, I copy/ pasted your code into my IntelliJ and compiled it. Got the expected output: test class

my entire solution (that I validated)

package com.codegym.task.task23.task2307;

/*

*/

public class Solution {
    public static final String TEST = "test";

    public static class TEST {
        @Override
        public String toString() {
            return "test class";
        }
    }

    static Object obj;

    public static void main(String[] args) {
        // obj = Solution.TEST;

        obj = new Solution.TEST();
        System.out.println(obj);
    }
}
