(Java Only)

Design a class BallGame that has the following instance variables and properties:

Name of first team and name of second team

Number of players in each team (one single variable)

Number of substitutes (one single variable)

Score of first and second team

- Provide a default constructor that sets names of teams to Unknown, number of players, substitutes and scores to 0.

- Provide a constructor that accepts specific values for each of the private members. Throw an exception (of your design) if the numbers are negative.

- Provide accessors for each of the members

- Provide mutators for each of the private members. Throw an exception (of your design) if the numbers are negative.

- Provide a method TeamAScored and TeamBScored that increases the score of the appropriate team by a specified value (i.e TeamAScored accepts an integer). Throw an exception (of your choice) if the values are negative.

- A method display that displays all attributes of an object

- Povide a method Equal that accepts an object BallGame and returns true if the object is equal to current object and false otherwise.

- Provide a method WhoIsWinning that returns the name of the winning team or Draw if both have same score.

B. Derive a class SoccerGame that has in addition the following:

Principal Referees name

Number of players substituted

- Provide a default constructor that sets team names and referees name to unknown, number of payers to 11, number of substitutes to 5 and the score of each team as well as number of players substituted to 0.

- Provide a constructor that accepts the names of the teams and the referees name.

- Provide accessors and mutators for referees name and number of players substituted. Throw an exception (of your design) if the numbers are negative.

- Override the method display to display all private attributes.

- Override the method Equal to compare two SoccerGames

- Override TeamAScored and TeamBScored that accepts an integer to increase the score of the appropriate team by 1 even if the number specified is larger than 1.

- Overload TeamAScored and TeamBScored (no input parameter) to increase the score of the appropriate team by 1.

- Provide a method SubstitutionA, SubstitutionB that increases the number of players substituted for the appropriate team by 1 if it is less than 3, otherwise it displays No more substitutions allowed.

C. Write a class tester (main) where you test every method and constructor of both classes. Print the output of your program.
