Question

2. Activity Directions: Create a UML diagram and then write the code for the object classes
needed for your UNO game. You will need a minimum of three classes:
a. A Card class (models an individual UNO card)
b. A Hand class (models a player's hand)
c. A Deck class (models the entire UNO deck)
You may add other classes as you see fit.
Test your program by writing a console application (a driver program) that creates a deck
of UNO cards, deals the cards to two or more players, and displays the contents of each
player's hand.

I am using Java 8 and the ide eclipse for testing
