Write java program that creates three threads. The first thread displays "Good Morning" for every one second, the second thread displays "Hello" for every two seconds and third thread displays "Welcome" for every three seconds.

class A extends Thread
{
     public void run()
     {
    try
    {
        while(true)
        {
           sleep(1000);
           System.out.println("good morning");
        }
    }
    catch(Exception e)
    { }
      }
}
class B extends Thread
{
      public void run()
      {
    try
    {
        while(true)
        {
        sleep(2000);
        System.out.println("hello");
        }
        }
      catch(Exception e)
    { }
      }
}
class C extends Thread
{
    public void run()
     {
    try
    {
        while(true)
        {
            sleep(3000);
            System.out.println("welcome");
        }
    }
    catch(Exception e)
    { }
     }
}
class ThreadDemo13
{
    public static void main(String args[])
    {
        A t1=new A();
        B t2=new B();
        C t3=new C();
        t1.start();
        t2.start();
        t3.start();
    }
}
