  1. What will be the output of the program?

     public class CommandArgs 
 {     
    public static void main(String [] args)              
    {       
         String s1 = args[1];         
         String s2 = args[2];         
         String s3 = args[3];         
         String s4 = args[4];         
         System.out.print(" args[2] = " + s2)        

   } 
 
 }

    Answer : Option D

    Explanation :

    An exception is thrown because in the code String s4 = args[4];, the array index (the fifth element) is out of bounds. The exception thrown is the cleverly named ArrayIndexOutOfBoundsException.
