java-我如何解决我的方法不能应用于给定类型错误为我的TicTacToe游戏？

Question

  public boolean addMove(int row, int column) {
  boolean nonacceptable = true;
  while (nonacceptable) {
     System.out.println("Which row and column would you like to enter your mark? Enter the row and column between 0 and 2 separated by a space.");
     row = input.nextInt();
     column = input.nextInt();
     if ((row >= 0 && row <=2) && (column >= 0 && column <=2)) { //make sure user entered a number between 0 and 2
        if (gameBoard[row][column] != ' ') 
           System.out.println("Sorry, this position is not open!");

        else {
           gameBoard[row][column] = currentMark;
           nonacceptable = false;
        }
     }   
     else 
        System.out.println("That position is not between 0 and 2!");
     }
     return nonacceptable;     

  public void letsPlay() {
  while (true) {
     displayBoard();
     gameOptions();
     int choice = input.nextInt();
     if (choice == 1) {
        if (addMove()) {
           displayBoard();
           checkWinner();
           System.exit(0);
        }
        else if (!boardFull()) {
           displayBoard();
           System.out.println("Board full!");
           System.exit(0);
        }
        else {
           whoseTurn();
        }
     }
     else if (choice == 2) 
        restart();
     else if (choice == 3) 
        System.exit(0);
     else 
        System.out.println("Try again!");
  }
}

当我编译时，我得到了这个错误：TicTacToe.java:110:error：TicTacToe类中的方法addMove不能应用于给定的类型；if（addMove（））{^required:int,int found：无参数原因：实际和正式参数列表长度不同1错误

我怎么才能修好这个？

Answer 1

很清楚。

addMove函数签名接受两个参数

public boolean addMove(int row, int column) { 
                         ^          ^

无论何时要调用或使用addMove函数，都必须遵循在签名函数中定义的规则。
