我正在使用Java进行编码，我将在星期五之前完成一个最终项目，并且我完成了所有工作，但我无法在最后修复括号，所以整个事情都搞砸了。由于某种原因，标签列表将无法在我的代码中使用。请看下面。我知道他们都很容易修复，但我似乎无法搞清楚！任何帮助表示赞赏。谢谢！我需要添加/修复哪些括号？
编辑！ 到处都没有回到我班级的位置 我定义了它们。 bestMove gameEnd 赢得 移动

您在代码中错过了相当多的匹配/右括号。不知道你想在哪里放置方法possibleMoves（），但是发布的原始代码应该如下工作：
public class Game {
position position = new position();
// the word button has a red mark next to the semicolon
protected Component button;
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
private Game game;
private int idx;
public void run() {
JFrame frame = new JFrame("Java TTT");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new GridLayout(3, 3));
game = new Game();
final JButton[] buttons = new JButton[9];
for (int i = 0; i < 9; i++) {
idx = i;
final JButton button = new JButton();
buttons[i] = button;
button.setPreferredSize(new Dimension(100, 100));
button.setBackground(Color.BLACK);
button.setOpaque(true);
button.setFont(new Font(null, Font.PLAIN, 100));
button.addMouseListener(new MouseListener() {
public void mouseReleased(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mouseEntered(MouseEvent e) {}
@Override
public void mouseClicked(MouseEvent e) {
button.setText("" + game.position.turn);
game.move(idx);
if (!game.position.gameEnd()) {
int best = game.position.bestMove();
buttons[best].setText("" + game.position.turn);
game.move(best);
}
if (game.position.gameEnd()) {
String message = "";
if (game.position.win('x')) {
message = "You won! (Mr. Lebron I made the game let you win, I think that deserves an A [Quit to play again])";
} else if (game.position.win('o')) {
message = "Computer won! (I think I still deserve an A [Quit to play again])";
} else {
message = "It's a tie! (Good try though [Quit to play again])";
}
JOptionPane.showMessageDialog(null, message);
}
}
});
frame.add(button);
}
// realize components
frame.pack();
frame.setVisible(true);
}
}
}
protected void move(int idx)
{
// the words position
position = position.move(idx);
//the following bracket
}
}

下载sublime之类的编辑器，然后在该编辑器中打开该文件。
当您将光标移动到括号位置时，它会显示每个对应的括号。
如果你更正了文件中的缩进，你会发现。
你也可以给jsFormat一个：https://stackoverflow.com/a/12867043/1069083

对于列表错误，您必须导入java.util。*
import java.util.*
导入LinkedList不包括使用列表。
