我今天的问题是你。当我在我的程序中完成一个游戏并询问我是否想要玩另一个游戏时。我会输入是。什么都不会发生。我必须输入Yes两次才能继续进行另一场比赛，然后当我的“clearTable（）;”方法启动，它只替换我的程序中的X而不是O.
有人可以向我解释为什么它不会从我的程序和x中删除O？无论如何，我的方法对我来说非常有意义。
static void clearTable(){
for(int i = 0; i < table.length; i++){
table[i][i] = ' ';
}
}
它将循环直到所有内容都在其中。我不知道为什么它现在不包括O.
我所担心的另一个问题是，在我完成游戏后输入“No”以便我的程序退出。我必须两次输入“No”，然后再次显示我的表，表格也不会被清除。这不应该是发生的事情。我的程序应该打印玩家的统计数据然后退出。有什么想法吗？
答案 0 :(得分：2)
据我所知，table是一个二维数组，如果你只使用for循环并使用table.length();，它将无法通过整个数组。您的clearTable功能只有在通过整个阵列时才能通过table[0][0]，table[1][1]和table[2][2]。您应该创建另一个内部for循环并使用table[0].length，它将返回数组中第二个维度的大小。
static void clearTable(){
for(int i = 0; i < table.length; i++)
for(int j=0; j< table[0].length; j++)
table[i][j] = ' ';
}
我希望它有效。
至于双＆＃34;是＆＃34;由于你在s.next()中调用了if函数，并且在你回答了第一个函数后，它会调用s.next()，因此导致了＃34;否＃34;功能再次。相反，将答案保存在字符串中并将其比较如下：
string ans = s.next();
if(ans.equals("Yes"))
break;
else if(ans.equals("No")) {
continuePlaying = false;
System.out.println("Statistitcs:");
System.out.println(p1 + p1Wins + "/" + gamesCounter);
System.out.println(p2 + p2Wins + "/" + gamesCounter);
break;
}
