Java - 將用戶輸入分配給變量並顯示Scoreboard

Question

我知道這是非常基本的Java，但我正在嘗試學習。有人能幫我理解我的錯誤，我該怎麼做來解決它？

package com.company; 

import java.util.Scanner; 

public class Main { 

    public static void main(String[] args) { 
     int teamA = 0; 
     int teamB = 0; 


     //asks for the team selection 
     System.out.println("Would you like to be in Team A or Tema B? Write A for team A and B for team B"); 
     Scanner input = new Scanner(System.in); 
     int result = input.nextInt(); 

     public String scoreBoard() { 
      String displayScoreBoard = "No Score"; 
      if (result.toString == "A" || result.toString == "a"){ 
       teamA++; 
       displayScoreBoard = "Score of TeamX is" + teamA; 
      } else if (result.toString == "B" || result.toString == "b"){ 
       teamB++; 
       displayScoreBoard = "Score of TeamY is" + teamB; 
      } System.out.println(displayScoreBoard.toString); 
     } 


     // write your code here 
    } 
}

你犯了幾個錯誤。例如，你在一個函數中寫了一個函數。你最好不要那樣做。看看我的代碼。如果您有任何問題，請詢問;）

更新：由於評論應該有一個循環，我已經調整了代碼。

import java.util.Scanner; 
public class Main{ 

    public static void main(String[] args) { 
     int teamA = 0; 
     int teamB = 0; 


     //asks for the team selection 
     while(true) { 
      System.out.println("Would you like to be in Team A or Tema B? Write A for team A and B for team B. Type anything else to quit."); 
      Scanner input = new Scanner(System.in); 
      String result = input.next(); 


      if (result.toUpperCase().equals("A")) { 
       System.out.println("Score of TeamX is" + ++teamA); 
      } else if (result.toUpperCase().equals("B")) { 
       System.out.println("Score of TeamY is" + ++teamB); 
      } 
       else { 
        break; 
       } 

      } 

     } 

}
