jframe - 如何使用 JButton 关闭 JFrame 并无限打开同一框架的新框架

Question

我正在用 Java 为我的班级制作一个游戏，我希望它在游戏结束时，这个“开始新游戏”按钮关闭当前窗口并创建一个新窗口，这样我就可以无限玩游戏。问题是，它会打开一个新窗口，但不会关闭旧窗口。我无法访问内部类中的静态变量，因此无法使用 .setVisible(false);。有任何想法吗？我是新手，我真的很想学习。谢谢！

        start.addActionListener( new game() );
        top.add( start );

    }
}

和我的主要方法：

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class GameApp
{
    public static void main ( String args[] )
    {
        JFrame f = new GameGUI();
        f.setLocation( 400, 230 );
        f.setSize( 640, 120 );
        f.setResizable( true );
        f.setVisible( true );`enter code here`
    }
}
