Java Program to create two threads which will display numbers from 1 to 10 with delay of 1 second

Write a Java program to create two threads, which alternately displays numbers from 1 to 10. Each thread sleeps for 1 second before displaying next number.

Source Code

class One extends Thread {
	
	public void run() {
		
		for(int i=1; i<=10; i++) {
			System.out.println("One : "+i);
			
			try {
				Thread.sleep(1000);
			}
			catch (InterruptedException ie) { }
		}
	}
}

class Two extends Thread {
	
	public void run() {
		
		for(int i=1; i<=10; i++) {
			System.out.println("Two : "+i);
			
			try {
				Thread.sleep(1000);
			}
			catch (InterruptedException ie) { }
		}
	}
}

public class AlternateTwoThreads {

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

}

Output

One : 1
Two : 1
Two : 2
One : 2
One : 3
Two : 3
One : 4
Two : 4
One : 5
Two : 5
One : 6
Two : 6
One : 7
Two : 7
One : 8
Two : 8
One : 9
Two : 9
One : 10
Two : 10
