java - 如何正确更新我的String数组？

public static String[][] possibleOutcomes(Scanner fileScan,int weaponNumber)
   {
      int numberOfOutcomes = (int)Math.pow(weaponNumber,2);
      String[][] outcomes = new String[numberOfOutcomes][numberOfOutcomes];
      String line = fileScan.nextLine();
      Scanner lineScan = new Scanner(line);
      fileScan.nextLine();
      fileScan.nextLine();
      while (fileScan.hasNextLine())
      {
         String userWeapon = lineScan.next();
         String computerWeapon = lineScan.next();
         String possibleTie = lineScan.next();
         if (possibleTie.equals("ties"))
            outcomes[userWeapon][computerWeapon] = possibleTie;
         else
            outcomes[userWeapon][computerWeapon] = lineScan.next();
      }
      return outcomes;
   }

错误消息：我认为这是我的输入是整数，即使它们设置为String。我该怎么办？


  RPSL.java:57：错误：类型不兼容：字符串无法转换为
  整型
                  结果[userWeapon] [computerWeapon] =可能的领带；

最佳答案

您将userWeapon和computerWeapon声明为字符串，无法使用它们来访问数组。而是从扫描仪读取一个整数（请参见Scanner#nextInt）。

int userWeapon = lineScan.nextInt();
int computerWeapon = lineScan.nextInt();
String possibleTie = lineScan.next();
if (possibleTie.equals("ties"))
    outcomes[userWeapon][computerWeapon] = possibleTie;
else
    outcomes[userWeapon][computerWeapon] = lineScan.next();
