I got smth wrong?

Question about the task

Under discussion

I d'ont understand it it seems to me that the output is correct, the checks are in place and I use the run method as a recursive threag generator. I am not very clear on what I am missing here. Could you give a hand? :)

1. Change the GenerateThread class to make it a thread.
2. Create a GenerateThread constructor, which must:
2.1. Call the superclass's constructor, passing the created thread's number as a String. Use createdThreadCount.
2.2. Start the current thread.
2.3. The thread numbers must start with 1.
3. Override the toString method: inside GenerateThread, use Alt+Insert -> Override Methods. Start typing "toString".
3.1. The toString method must return the current thread number and the word "created". Use getName().

Example:
8 created

4. If the number of created threads is less than Solution.count, the run method must:
4.1. Create a new GenerateThread.
4.2. Display the thread created in Item 4.1.
5. In the end, 15 lines should be output to the console.

Requirements:

The GenerateThread class should inherit the Thread class.
The GenerateThread class must have a public no-argument constructor.
The GenerateThread class constructor should increment createdThreadCount and pass it as a string to the superclass constructor.
The GenerateThread class constructor must start the thread.
The GenerateThread class's toString method must return the thread name and the word " created". Example: "8 created".
If the number of created threads is less than Solution.count, the run method must create a new GenerateThread.
If the number of created threads is less than Solution.count, the run method must display the created thread.
The program's output must match the task conditions and indicate that all 15 threads have been created.

package com.codegym.task.task16.task1623; /* Creating threads recursively */ import java.awt.*; public class Solution { static int count = 15; static volatile int createdThreadCount = 0; public static void main(String[] args) throws InterruptedException { new GenerateThread(); } public static class GenerateThread extends Thread{ public GenerateThread() { super(String.valueOf(++createdThreadCount)); start(); } @Override public void run() { if(Solution.count >= createdThreadCount){ System.out.println(this); new GenerateThread(); } } @Override public String toString() { return this.getName() + " created"; } } }

I'm not sure if they have updated the task since this was originally posted, but I note that the line in the Main method is supposed to be

System.out.println(new GenerateThread());

This is also what needs to be in the run() method. 1 statement inside the if block is all it needs. Use the Main method to get the correct statement.

Try by removing the equals symbol at lin 28. It just asked to check less than not less than or equals to, i'm not sure.

Thanks mate but that did not help. I really have no idea what went wrong with that one.
