  1. What will be the output of the program?

      public class WaitTest
  {  
     public static void main(String [] args)    
      {     
         System.out.print("1 ");           
         synchronized(args)   
         {      
            System.out.print("2 ");                 
            try   
            {                     
               args.wait(); /* Line 11 */               
            }               
          catch(InterruptedException e){ }           
      }       
      System.out.print("3 "); 
    } 
 }

    2. A.

    It fails to compile because the IllegalMonitorStateException of wait() is not dealt with in line 11.
    B.

    1 2 3
    C.

    Answer : Option D

    Explanation :

    1 and 2 will be printed, but there will be no return from the wait call because no other thread will notify the main thread, so 3 will never be printed. The program is essentially frozen at line 11.

    A is incorrect; IllegalMonitorStateException is an unchecked exception so it doesn't have to be dealt with explicitly.

    B and C are incorrect; 3 will never be printed, since this program will never terminate because it will wait forever.
