Question

Write a java program with the following classes:

Class Player
Method Explanation:

play : will use a loop to generate a series of random numbers and add them to a total, which will be assigned to the variable score.
decideRank: will set the instance variable rank to “Level 1”, “Level 2”, “Level 3”, “Level 4” based on the value of score, and return that string.
getScore : will return score.
toString: will return a string of name, score and rank.
Must have all the accessors and mutators.

Class: Game:
The instance variable is an array of Player.
Method Explanation:

constructor Game (Player player[]): it will instantiate the instance variable with the passed Player array.
start: will use a loop to go through each Player of the instance variable player (the array player[]) and have each element (which is a Player object) call the play method.
end: print out “Game Ended…”
decideWinner: use the score method of Player to get the score of each Player object in the instance variable player. Compare and decide the winner. Return the Player object.
Must have all the accessors and mutators.

GameDriver: main method will declare and instantiate an array of Player and create a Game object with it. Then it will start the game (call the start method), end the game (call the end method). It will show the rank of each Player object and show the winner (you can call decideWinner in the print statement since this method returns the winning Player object). Here is a summary: in this main method, you are to call

( start(), end(), and decideWinner() through the Game object you declared at the beginning. All three methods are from the Game class.)

Thanks for the question, here are the 3 classes - Player, Game and GameDriver.

Let me know for any question or for any further help!
