如何使用JButton关闭JFrame并无限地打开同一帧的新帧

Question

我正在用Java制作我的课程游戏，我想要它，这样当游戏结束时，这就是＃34;开始新游戏＆＃34;按钮关闭当前窗口并创建一个新窗口，这样我就可以无限制地玩游戏。问题是，它打开了一个新窗口，但它并没有关闭旧窗口。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？我对这些东西很陌生，我真的很想学。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`
    }
}
