You will need to do the following things:

  1. Get a String of input from the user.
  2. Depending on whether the input is valid, announce the number’s value; otherwise, let the user know it is bad input.
  3. Write a method to verify whether or not the user’s input string is valid.
  4. Write a method to calculate the value of the user’s input string.
