10. Expanding the Class a. Write a concise and precise class invariant for the games instance variable in terms of the other instance variables. b. Write the prototype (method header) for a numWins method that returns the number of wins as its integer return value. It has no parameters. Write prototype only. c. You want to print a win-loss-tie record (such as 3-1-1) in Game.java. Describe in precise words (not code) the best way to go about doing this. What would change where? Two possibilities: 1) Create accessor methods for numWins, numLosses, num Ties on Record class. Call these from Game.java 2) Create a String method on Record class that returns formatted record. Call this from Game.java
