Simora [160]

Answer:

// Scanner class is imported to allow program receive user input

import java.util.Scanner;

// class is defined

public class PlayerRoster {

   // main method that begin program execution

  public static void main(String[] args) {

   // Scanner object scan is defined

     Scanner scan = new Scanner(System.in);

   // multi-dimensional array to hold the jersey number and rating

     int[][] players = new int[5][2];

   // boolean flag to keep program alive

     boolean keepAlive = true;

   // the user input is declared as input of type char

     char input;

     

   // for loop that receive 5 player jersey number and ratings

   // it assigns the received input to the already initialized array

     for (int i = 0; i < 5; i++) {

        System.out.println("Enter player " + (i+1) + "'s jersey number: ");

        players[i][0] = scan.nextInt();

        System.out.println("Enter player " + (i+1) + "'s rating: ");

        players[i][1] = scan.nextInt();

        System.out.println();

     }

   // a blank line is printed

     System.out.println();

   // a method is called to display players array

     outputRoster(players, 0);

     

   // while the flag is true

   // display the Menu by calling the outputMenu method

     while (keepAlive) {

        outputMenu();

       // user input is assigned to input

        input = scan.next().charAt(0);

       //  if user input is 'q' then program will quit

        if (input == 'q') {

           keepAlive = false;

           break;

        }

       //  else if input is o, then outputRoaster is called to display players

        else if (input == 'o') {

           outputRoster(players, 0);

        }

       //  else if input is 'u', then user is allowed to edit a player rating

        else if (input == 'u') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           System.out.println("Enter a new rating for the player: ");

           int newRating = scan.nextInt();

           for (int l = 0; l < 5; l++) {

              if (players[l][0] == jerseyNum) {

           }

        }

       //  else if input is 'a', user is allowed to add a new rating

        else if (input == 'a') {

           System.out.println("Enter a rating: ");

           int rating = scan.nextInt();

           outputRoster(players, rating);

        }

        // else if input is 'r', user is allowed to replace a player

        else if (input == 'r') {

           System.out.println("Enter a jersey number: ");

           int jerseyNum = scan.nextInt();

           boolean exists = true;

           for (int l = 0; l < 5; l++) {

              if (players[l][0] == jerseyNum) {

                 System.out.println("Enter a new jersey number: ");

                 players[l][0] = scan.nextInt();

                 System.out.println("Enter a rating for the new player: ");

                 players[l][1] = scan.nextInt();

              }

           }

           

        }

     }

     

     return;

  }

 

// this method take two parameters, players and min

// it then returns player with ratings greater than min

  public static void outputRoster(int[][] players, int min) {

     System.out.println(((min>0) ? ("ABOVE " + min) : ("ROSTER")));

     int item = 1;

     for (int[] player : players) {

        if (player[1] > min) {

           System.out.println("Player " + item + " -- Jersey number: " + player[0] + ", Rating: " + player[1]);

        }

        item++;

     }

     System.out.println();

  }

 

// outputMenu method to display the program menu

  public static void outputMenu() {

     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("o - Output roster");

     System.out.println("q - Quit\n");

     System.out.println("Choose an option: ");  

  }

}
