      A Java servlet class ?

      Hey everyone, I'm trying to generate two random numbers between 1 and 5 inclusive and displays the result of their addition, subtraction, multiplication and division?

      For example, something such as:

      4 + 4 = 8

      4 - 4 = 0

      4 * 4 = 16

      4 / 4 = 1
