我没有遇到任何编译错误，但是由于我的checkWinner方法甚至没有遇到，所以必须有一个逻辑错误。
这是我的checkWinner方法的代码：
public boolean checkWinner() {
for (int i=0;i<3;i++){
if ((gameBoard[i][0] == gameBoard[i][1]) && (gameBoard[i][1] == gameBoard[i][2])) { //check every row to find a match
System.out.println(currentMark + "wins!");
}
else if ((gameBoard[0][i] == gameBoard[1][i]) && (gameBoard[1][i] == gameBoard[2][i])) { //checks every column to find a match
System.out.println(currentMark + "wins!");
}
}
if ((gameBoard[0][0] == gameBoard[1][1]) && (gameBoard[1][1] == gameBoard[2][2])) { //checks first diagonal
System.out.println(currentMark + "wins!");
}
else if ((gameBoard[0][2] == gameBoard[1][1]) && (gameBoard[1][1] == gameBoard[2][0])) { //checks second diagonal
System.out.println(currentMark + "wins!");
}
else
System.out.println("Tie!");
return true;
}
这是我的游戏方法，在用户输入动作后，我每次都使用checkWinner检查赢家。
public void letsPlay() {
while (true) {
displayBoard();
gameOptions();
int choice = input.nextInt();
if (choice == 1) {
if (addMove(input.nextInt(),input.nextInt())) {
displayBoard();
checkWinner();
whoseTurn();
System.exit(0);
}
我不确定我的checkWinners方法是否应该是我的addMove方法的一部分...这是addMove
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;
}
我如何将其合并到addMove方法中或对其进行更改，以使其作为自己的方法工作？
最佳答案
看起来当用户输入有效答案时，nonacceptable设置为false，从而退出while(nonacceptable)循环。但是然后您返回nonacceptable（这是错误的），这意味着检查if (addMove())将不通过（因此不会调用checkWinner）。您可以尝试将if语句向下移动，如下所示：
addMove();
displayBoard();
if (checkWinner()) {
System.exit(0);
}
whoseTurn();
但是，只有在比赛获胜或平局的情况下，您才需要更改
checkWinner以返回true，否则返回false。
