   if ( number1 != number2)
    System.out.println( number1 + " not equal " + number2 );

   if ( number1 < number2)
    System.out.println( number1 + " less than " + number2 );

   if ( number1 > number2)
    System.out.println( number1 + " greater than " + number2 );

   if ( number1 <= number2)
    System.out.println( number1 + " less than or equal " + number2 );

   if ( number1 >= number2)
    System.out.println( number1 + " greater than or equal " + number2 );

            JOptionPane.showMessageDialog(one,"Enter Valid Integer Value");
