The first thread shows proper result, but it seems to run infinitely after that, i cant really get where is the mistake in the code, tried to put currentThread.join() method in other places but its not helping.
package com.codegym.task.task16.task1622;
/*
Consecutive threads
*/
public class Solution {
public volatile static int COUNT = 4;
public static void main(String[] args) throws InterruptedException {
for (int i = 0; i < COUNT; i++) {
new SleepingThread();
Thread.currentThread().join();
}
}
public static class SleepingThread extends Thread {
private static volatile int threadCount = 0;
private volatile int countdownIndex = COUNT;
public SleepingThread() {
super(String.valueOf(++threadCount));
start();
}
public void run() {
while (true) {
System.out.println(this);
if (--countdownIndex == 0) return;
try{
Thread.sleep(10);
}
catch (InterruptedException e){
System.out.println("Thread interrupted");
}
}
}
public String toString() {
return "#" + getName() + ": " + countdownIndex;
}
}
}
