5.13 Ch 5 Program: Soccer team roster (Java)

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)

Ex:

Here is what I have so far:

import java.util.Scanner;

public class PlayerRoster {
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);
      final int NUM_PPL = 5;
      int[] jerseyNum = new int[NUM_PPL];
      int[] ratingNum = new int[NUM_PPL];
      int i = 0;
      char menuChar = 'b';
      int changedPlayer = 0;
      int newRating = 0;
      int ratingAbove = 0;
     
      for (i = 0; i < NUM_PPL; ++i) {
         System.out.println("Enter player " + (i + 1) + "'s jersey number:");
         jerseyNum[i] = scnr.nextInt();
         System.out.println("Enter player " + (i + 1) + "'s rating:");
         ratingNum[i] = scnr.nextInt();
         System.out.println("");
      }
     
      System.out.println("ROSTER");
      for (i = 0; i < NUM_PPL; ++i) {
         System.out.println("Player " + (i + 1) + " -- Jersey number: " + jerseyNum[i] + ", Rating: " + ratingNum[i]);
      }
     
      System.out.println("");
     
      while (menuChar != 'q') {
         if (menuChar == 'o') {
            System.out.println("ROSTER");
            for (i = 0; i < NUM_PPL; ++i) {
               System.out.println("Player " + (i + 1) + " -- Jersey number: " + jerseyNum[i] + ", Rating: " + ratingNum[i]);
            }
         }
        
           
         System.out.println("MENU");
         System.out.println("u - Update player rating");
         System.out.println("a - Output players above a rating");
         System.out.println("r - Replace player");
         System.out.println("q - Quit");
         System.out.println("");
         System.out.println("Choose an option:");
         menuChar = scnr.next().charAt(0);
      }
    
     
  
      return;
   }
}
