Question

我正在使用JFrame，JPanel，JButton和actionListener对游戏进行编程，并且我希望有一个按钮，当按下该按钮时会重新启动游戏。基本上我希望当前的Jframe关闭并重新打开一个新的不同的Jframe。我希望它就像你按下开始新游戏的按钮一样。这是我的代码：

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Start {
public static int a;
public static JButton[][] gumbi = new JButton[15][15];
public static JFrame okno = new JFrame("Nonogram");
public static void main(String[] args) {

    okno.setVisible(true);
    okno.setSize(800, 800);
    okno.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel(new BorderLayout());
    okno.add(panel);

    JPanel polje = new JPanel(new GridLayout(15, 15));
    panel.add(polje, BorderLayout.CENTER);

    a = 0;
    int b = 1;
    // String I = I;
    for (int i = 0; i < 15; i++) {
        for (int j = 0; j < 15; j++) {
            if (i < 5 && j < 5) {
                gumbi[i][j] = new JButton();
                gumbi[i][j].setBackground(Color.GREEN);
                // gumbi[i][j].addActionListener(new Listener(gumbi));
                polje.add(gumbi[i][j]);
            } else if (i < 5 || j < 5) {
