Playing With Cards Write a class that defines an enumerated type named Rank with values ace, two, three, four, five, six, seven, eight, nine, ten, jack, queen, king. The main method should do the following: 1. Declare variables highCard , faceCard , card1 , and card2 of type Rank. 2. Assign highCard to be an ace, faceCard to be a jack, queen or king (your choice), and card1 and card2 to be two different numbered cards (two through ten - your choice). 3. Print a line, using the highCard and faceCard objects, in the following format: A blackjack hand: ace and ..... The faceCard variable should be printed instead of the dots. 4. Declare two variables card1Val and card2Val of type int and assign them the face value of your card1 and card2 objects. Use your card1 and card2 variables and the ordinal method associated with enumerated types. Remember that the face value of two is 2, three is 3, and so on so you need to make a slight adjustment to the ordinal value of the enumerated type. 5. Print two lines, using the card1 and card2 objects and the name method, as follows: A two card hand: (print card1 and card2) Hand value: (print the sum of the face values of the two cards) 35 Chapter 3: Using Classes and Objects

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
