Question

You may earn additional 5 extra points if you simulate the real lottery "MEGA MILLIONS". If you create a good GUI you would be able to receive additional 3 points The rule of the game is (from Internet): The Lottery game in which the ticket purchaserselects, or has the computer randomly assign five (5)" different "numbers from Field 1 which includes a range of consecutive numbers from one (1) to fifty-six (56) and one (1) number from Field 2 which includes a range of consecutive numbers from one (1) to forty-six (46), shall be called MEGA MILLIONS" For example, the winning numbers from Field 1 may be (03, 05, 10, 20, 43) and from Field 2 105). As you can see the number from Field 2 may be the same as one of the numbers of Field 1. You have different ways to develop your algorithm and code. One of the ways is to use ArrayList. You are free to select some other way. Please give UML diagrams for all classes.
