Example: thread join java

class ThreadJoining extends Thread 
{ 
    @Override
    public void run() 
    { 
        for (int i = 0; i < 2; i++) 
        { 
            try
            { 
                Thread.sleep(500); 
                System.out.println("Current Thread: "
                        + Thread.currentThread().getName()); 
            } 
  
            catch(Exception ex) 
            { 
                System.out.println("Exception has" + 
                                " been caught" + ex); 
            } 
            System.out.println(i); 
        } 
    } 
}
