Question

I need a little bit of help on this one Need JAVA code. Thanks guys!

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team.

(1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int array and the ratings in another int array. Output these arrays (i.e., output the roster). (3 pts)

Ex:

(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing. (2 pt)

Ex:

(3) Implement the "Output roster" menu option. (1 pt)

Ex:

(4) Implement the "Update player rating" menu option. Prompt the user for a player's jersey number. Prompt again for a new rating for the player, and then change that player's rating. (1 pt)

Ex:

(5) Implement the "Output players above a rating" menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. (2 pts)

Ex:

(6) Implement the "Replace player" menu option. Prompt the user for the jersey number of the player to replace. If the player is in the roster, then prompt again for a new jersey number and rating. Update the replaced player's jersey number and rating. (2 pts)

CODE :
