这是一个tic tac toe计划，这是董事会成员：

public class board {
    private char[] board;

    public board() {
        board = new char[]
                {'0', '1', '2',
                '3', '4', '5',
                '6', '7', '8'};
                }
    public void setSpot(char player, int position) {
        if (board[position] == position+48) {
            board[position] = player;
        }else {
            System.out.println("Incorrect move, turn skipped");
        }
    }

    public boolean detectWin(char player){
        if((board[0] == player && board[1] == player && board[2] == player) 
|| (board[3] == player && board[4] == player && board[5] == player) || 
(board[6] == player && board[7] == player && board[8] == player) || 
(board[0] == player && board[3] == player && board[6] == player) || 
(board[1] == player && board[4] == player && board[7] == player) || 
(board[2] == player && board[5] == player && board[8] == player) || 
(board[0] == player && board[4] == player && board[8] == player) || 
(board[2] == player && board[4] == player && board[6] == player))
            return true;
        else
            return false;
    }
    public boolean detectTie() {
        for (int i = 0; i > board.length; i++) {
            if (board[i] == i+48)
                return false;
        }
        return true;
    }

    public void printBoard() {
        System.out.println(board[0] + " | " +board[1] +" | " +board[2]);
        System.out.println("---------");
        System.out.println(board[3] + " | " + board[4] + " | " + board[5]);
        System.out.println("--------");
        System.out.println(board[6] + " | " + board [7] + " | " + board[8]);

    }
}

它一直被终止，我无法找到原因。没有错误消息。

代码中的简单拼写错误，更改detectTie如下：

public boolean detectTie() {
    for (int i = 0; i < board.length; i++) {
        if (board[i] == i+48)
            return false;
    }
    return true;
}

你应该好。你使用int i = 0;我＆gt; board.length; i ++，所以我从0开始，并且这不超过板数组长度所以它从不执行循环并且只返回true，这反过来导致！b.detectTie（）返回false，这意味着主while循环是从未执行过。

Java程序在运行之前终止
