Question

Looking for some Java Code. My code is still producing errors UGH!!

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'S MY CODE:

import java.util.Scanner;

public class PlayerRoster {
public static void main(String[] args) {

int[] jerseyNumber = new int[5];
int[] rating = new int[5];
Scanner sc = new Scanner(System.in);

for (int i = 0; i < jerseyNumber.length; i++) {
System.out.println("Enter player " + (i + 1) + "'s jersey number: ");
jerseyNumber[i] = sc.nextInt();
System.out.println("Enter player " + (i + 1) + "'s rating: ");
rating[i] = sc.nextInt();
System.out.println("");
}
for (int i = 0; i < jerseyNumber.length; i++) {
System.out.println("Player " + (i + 1) + " -- Jersey number: " + jerseyNumber[i] + ", Rating: " + rating[i]);
}
while (true) {
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 ");
System.out.println(" Choose an option: ");
char choice = sc.next().charAt(0);
if (choice == 'u') {
System.out.println("Enter a jersey number: ");
int number = sc.nextInt();

for (int i = 0; i < jerseyNumber.length; i++) {
if (jerseyNumber[i] == number) {
System.out.println("Enter a new rating for player: ");
rating[i] = sc.nextInt();
}
}
}
if (choice == 'a') {
System.out.print("Enter a rating: ");
int rate = sc.nextInt();
System.out.println("ABOVE " + rate);

for (int i = 0; i < jerseyNumber.length; i++) {
if (rating[i] > rate) {
System.out.println("Player " + (i + 1) + "-- Jersey number: " + jerseyNumber[i] + ", Rating: " + rating[i]);
}
}
}
if (choice == 'r') {
System.out.println("Enter a jersey number: ");
int number = sc.nextInt();

for (int i = 0; i < jerseyNumber.length; i++) {
if (jerseyNumber[i] == number) {
System.out.println("Enter a new jersey number: ");
jerseyNumber[i] = sc.nextInt();
System.out.println("Enter a rating for the new player: ");
rating[i] = sc.nextInt();
}
}
}
if (choice == 'o') {
System.out.println(" ROSTER ");
for (int i = 0; i < jerseyNumber.length; i++) {

}
}
if (choice == 'q') {
System.exit(0);
}
}
}
}

//The code is more or less the same. I found that you have to print "ROSTER" even the first time and you missed a space in the output option of the loop. The undelying logic of your code is flawless.
