Rock, Paper, Scissors is a two-player game in which each player chooses one of three items. If both players choose the same item, the game is tied. Otherwise, the rules that determine the winner are:

(a) Rock always beats Scissors (Rock crushes Scissors)

(b) Scissors always beats Paper (Scissors cut Paper)

(c) Paper always beats Rock (Paper covers Rock) Implement function rps() that takes the choice ('R', 'P', or 'S') of player 1 and the choice of player 2, and returns −1 if player 1 wins, 1 if player 2 wins, or 0 if there is a tie.

>>> rps('R', 'P') 1

>>> rps('R', 'S') -1

>>> rps('S', 'S') 0

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student.java, undergraduatestudent.java, graduatestudent.java, studentatlarge.java, and studentdemo.java.
