Java program for creating multiple threads

Editorial Team — Sun, 04 Oct 2009 15:10:08 +0000

class NewThread implements Runnable
{
	String name;
	Thread t;
	NewThread(String threadname)
	{
		name=threadname;
		t=new Thread(this,name);
		System.out.println("New Thread:"+t);
		t.start();
	}
	public void run()
	{
		try
		{
			for(int i=5;i>0;i--)
			{
				System.out.println(name+ ":"+i);
				Thread.sleep(1000);
			}
		}
		catch(InterruptedException e)
		{
			System.out.println(name+" Interrupted");
		}
		System.out.println(name+" exiting");
	}
}
class MultiThreadDemo
{
	
public static void main(String[] args)
	{
		new NewThread("One");
		new NewThread("Two");
		new NewThread("Three");
		try
		{
			Thread.sleep(10000);
		}
		catch(InterruptedException e)
		{
			System.out.println("Main Thread Interrupted");
		}
		System.out.println("Main Thread Exiting");
	}
}

Output:

New Thread :Thread[One,5,main]
New Thread : Thread[Two,5,main]
One:5
Two:5
New Thread : Thread[Three,5,main]
Three:5
One:4
Three:4
Two:4
One:3
Three:3
Two:3
One:2
Three:2
Two:2
One:1
Three:1
Two:1
One exiting
Three exiting
Two exiting
Main Thread Exiting
