Abstract Problem

Create an abstract class called AbstractProblem. That class should have the following:

  • A private variable to hold the start time.
  • A constructor that initializes the start time using System.currentTimeMillis()
  • A public method called completion that accepts a long variable that prints out the following to the console:
  • “Answer L in X seconds.”, where L is the long variable that was passed into it and X is the difference between now and the saved start time. Hint: millis need to be divided by 1000 to get seconds.

Do you have a start to this? I'd be glad to help out, but this sounds like homework ;)
