Question

This is my simple program in Java:

public class Counter extends Thread {

    public static void main(String args[]) {    
        Thread t1 = new Thread();
        Thread t2 = new Thread();
        t1.start();
        t2.start();
    }
}

I am using Windows Operating System 32-bit. My question is, how can we know how many Threads are created in the program and how many Threads are running? Is there any such tool?

Answer 1

System.out.println(“Number of active threads from the given thread: ” + Thread.activeCount());
