Syntax of sleep() method in java

The Thread class provides two methods for sleeping a thread: public static void sleep(long miliseconds)throws InterruptedException public static void sleep(long miliseconds, int nanos)throws InterruptedException

Example sleep method in java

class TestSleepMethod1 extends Thread{  

 public void run(){  

  for(int i=1;i<5;i++){  

    try{Thread.sleep(500);}catch(InterruptedException e){System.out.println(e);}  

    System.out.println(i);  

  }  

 }  

 public static void main(String args[]){  

  TestSleepMethod1 t1=new TestSleepMethod1();  

  TestSleepMethod1 t2=new TestSleepMethod1();  

   

  t1.start();  

  t2.start();  

 }  

}

As you know well that at a time only one thread is executed. If you sleep a thread for the specified time,the thread shedular picks up another thread and so on.
