Java tic tac toe，计算机can'；t温（爪哇）

我正在用java编写一个井字游戏。我还没做完，但我已经做了一些事情，应该可以玩了。问题是，我已经完成了代码，所以计算机应该能够赢，但它不工作。当电脑连续三次显示“电脑赢了”时，它会继续播放

代码如下：

import java.util.Scanner;
import java.util.concurrent.ThreadLocalRandom;;

public class Main {

static int[][] gameBoard = new int[3][3];
static Scanner userInput = new Scanner(System.in);


public static void main(String[] args) {

    //initialize game board
    for(int x=0;x<3; x++){
        for(int i=0;i<3;i++){
            gameBoard[x][i] = 0;
        }
    }

    gameLoop();




}

static void gameLoop(){
    boolean loop = true;

    while(loop==true){
    displayBoard();
    playerMove();
    if(checkIfWin() == true){
        loop = false;
    }

    if(checkIfLose() == true)
        loop = false;

    computerInput();
    }

}

static void playerMove(){
    String playerInput;

    System.out.println();
    System.out.print("Your move: ");
    playerInput = userInput.next();

    if(playerInput.equals("a1")){
        if(gameBoard[0][0] == 0){
            gameBoard[0][0] = 1;
        }else{
            System.out.println("That one is already taken!");
        }

    }else if(playerInput.equals("a2")){
        if(gameBoard[1][0] == 0){
            gameBoard[1][0] = 1;
        }else{
            System.out.println("That one is already taken!");
        }
    }else if(playerInput.equals("a3")){
        if(gameBoard[2][0] == 0){
            gameBoard[2][0] = 1;
        }else{
            System.out.println("That one is already taken!");
        }
    }else if(playerInput.equals("b1")){
        if(gameBoard[0][1] == 0){
            gameBoard[0][1] = 1;
        }else{
            System.out.println("That one is already taken!");
        }
    }else if(playerInput.equals("b2")){
        if(gameBoard[1][1] == 0){
            gameBoard[1][1] = 1;
        }else{
            System.out.println("That one is already taken!");
        }
    }else if(playerInput.equals("b3")){
        if(gameBoard[2][1] == 0){
            gameBoard[2][1] = 1;
        }else{
            System.out.println("That one is already taken!");
        }
    }else if(playerInput.equals("c1")){
        if(gameBoard[0][2] == 0){
            gameBoard[0][2] = 1;

为计算机输入添加循环检查，以确保如果游戏已在该迭代中完成，则不会触发新的移动@Sh4d0wsPlyr他们在那里？由于计算机输入在循环设置为false后运行，它肯定会在决策后发挥更大的作用，因为循环将完成其迭代。如果你用If（循环）包装计算机移动，它可能会解决你的问题。我刚刚使用了你的代码，得到了“计算机赢！”？问题是什么？谁对这个问题投了赞成票？！这是一个很好的例子，通过调试他自己的代码可以很容易地解决问题。@redFIVE:这是在我的手机上写的，所以请给我至少两分钟的时间，在你开始投反对票之前，在尝试预览代码后添加评论rt是从最初的帖子中复制出来的，只是添加它以显示正确的上下文。
