      int result;

      System.out.print( "Enter first integer: " );
      x = input.nextInt();

      System.out.print( "Enter second integer: " );
      y = input.nextInt();
      
      System.out.print( "Enter third integer: " );
      z = input.nextInt();

      result = x * y * z;

      System.out.printf( "Product is %d\n", result );
