Java 对井字游戏没有意义

Question

这是我过去几周在 APCS 中的副项目，我几乎完成了。我基本上是在用 swing 制作一个简单的 gui，它有一个按钮网格并显示像井字游戏这样的图像。但是，我就是无法让获胜序列发挥作用。我已经使用了我在网上找到的方法，但仍然无法正常工作；事实上，它甚至没有意义。我有 1 个打印语句来测试值，它打印了 4 次。我完全迷路了。需要注意的是，我是在我的家用电脑上执行此操作的，所以我没有这台电脑上的图像，但我认为这不会影响程序...？

这是代码（我认为问题出在gameover()）

int XgoesFirst=0;
int[] press= {0,0,0,0,0,0,0,0,0};
int count=0;
int over=0;
String Xmess=("Cross for you laymens out there");
String Omess=("Naught for you laymens out there");
String rowWinner="";
String diagWinner="";
String columnWinner="";

private class CellButtonHandler implements ActionListener{
    public void actionPerformed(ActionEvent e)
    {

        ImageIcon xImage = new ImageIcon("images.jpg");

        JButton pressed=(JButton)(e.getSource());       
            if(gameover()){
                if(XgoesFirst==0){
                    pressed.setIcon(xImage);

                    pressed.setText(Xmess);
                    XgoesFirst=XgoesFirst+1;
                    press[count]+=1;
                    over++;
                }else if(XgoesFirst==1){
                    pressed.setIcon(new ImageIcon("O.jpg",""));

                    pressed.setText(Omess);
                    XgoesFirst=XgoesFirst-1;
                    press[count]+=1;
                    over++;
                }
            }
            count++;
            System.out.println(gameover());
        }
    }
}


public boolean gameover(){
    if(cells[0].getText().equals(cells[1].getText()) && cells[1].getText().equals(cells[2].getText())){
        return true;

                return true;
            }else{

                                return true;
                            }else{
                                if(cells[2].getText().equals(cells[4].getText()) && cells[4].getText().equals(cells[6].getText())){
                                    return true;
                                }else{
                                    if (over>7){

                                    }

            }
            return temp2;
    }
//  private class restart implements ActionListener
}

现在我使用的旧方法仍然存在，重启部分还没有完成，但这就是一切。 （我只是无法让逻辑工作的旧方法。我试图让它检测其中一个跳棋是否获胜或游戏是否结束，但我就是无法正确逻辑）

编辑获胜画面

NVM 我现在让它工作了，我只需要知道将它放在哪里，以便它在结束时激活。

Answer 1

这是您的代码，其中包含一些附加项和 cmets。我现在没有时间解释所有内容，但我稍后会编辑此答案并添加解释。看看看看，如果有什么令人困惑或错误的地方，请告诉我。

目前只支持玩一个游戏，然后你必须关闭并重新运行应用程序。哦，按钮只能按下一次，因为我在按下按钮后删除了按钮的MouseListener。
