   {
       int x;  
       x = argh.length;   
       for (int y = 1; y " " + argh[y]);
      }

    Answer : Option D

    Explanation :

    An exception is thrown because at some point in (System.out.print(" " + argh[y]);), the value of x will be equal to y, resulting in an attempt to access an index out of bounds for the array. Remember that you can access only as far as length - 1, so loop logical tests should use x as opposed to x .
