How to restart a program if a button is pressed in java?
Question
I'm programing a game using JFrame, JPanel, JButton and actionListener and I'd like to have a button that when pressed restarts the game. Basically I want the the current Jframe to close and to reopen a new different one. I want it to be like a button you press to start a new game. Here is my code:
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) {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.YELLOW);
// gumbi[i][j].addActionListener(new Listener(gumbi));
polje.add(gumbi[i][j]);
gumbi[i][j].setEnabled(false);
} else {
if (Math.random() <= 0.5) {
a += 1;
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.WHITE);
gumbi[i][j].setForeground(Color.RED);
// gumbi[i][j].addActionListener(new Listener(gumbi));
gumbi[i][j].setText("3");
polje.add(gumbi[i][j]);
} else {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.WHITE);
gumbi[i][j].setForeground(Color.WHITE);
// gumbi[i][j].addActionListener(new Listener(gumbi));
gumbi[i][j].setText("4");
polje.add(gumbi[i][j]);
}
}
}
}
for (int i = 0; i < 15; i++) {
for (int j = 0; j < 15; j++) {
gumbi[i][j].addActionListener(new Listener(gumbi));
}
}
int[] array = new int[105];
for (int i = 5; i < 15; i++) {

}
}
int[] array2 = new int[105];
for (int i = 0; i < 100; i++) {
array2[i] = -2;
}
for (int i = 0; i < 100; i++) {
if (array[i] == array[i + 1] && array[i] == 3 && (i + 1) % 10 != 0) {
b += 1;
} else if ((array[i] == 3 && array[i] != array[i + 1] && i < 99)
|| ((i + 1) % 10 == 0 && array[i] == 3)) {
array2[i] = b;
b = 1;
}
if ((i + 1) % 10 == 0) {

}
}
int x = 0;
int y = 0;
for (int i = 0; i <= 100; i++) {
// if(array2[(i-4) + (10*(j - 5))] != -2){

}
}
for (int i = 0; i < 101; i++) {
// System.out.println(array[i]);
if (array2[i] != -2)
System.out.print(array2[i] + " ");
}
for (int i = 5; i < 15; i++) {
for (int j = 5; j < 15; j++) {

gumbi[1][1].setText("?");
gumbi[1][2].setText("C");
for (int i = 5; i < 15; i++) {
for (int j = 5; j < 15; j++) {
// gumbi[i][j].setText(null);
}
}
}
}
and the actionListener:

import java.awt.event.ActionListener;
import javax.swing.JButton;

public class Listener implements ActionListener {

JFrame vprasaj = new JFrame("Navodila");
JPanel navodila = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
JLabel restart = new JLabel("Za zaceti novo igro pritisnite tipko R(restart)");
JLabel pregled = new JLabel("Za pregled veljavnosti trenutne pozicije pritisnite tipko C(check)");
public Listener(JButton[][] gumbi) {
this.gumbi = gumbi;
}
public void actionPerformed(ActionEvent e) {
JButton gumb = (JButton) e.getSource();
if (gumb.getBackground() == Color.WHITE) {
gumb.setBackground(Color.BLACK);

}
if(e.getSource() == gumbi[1][1]){
vprasaj.setVisible(true);
vprasaj.setSize(450, 200);
vprasaj.add(navodila);
c.gridx = 0;
c.gridy = 0;
navodila.add(restart, c);
c.gridx = 0;
c.gridy = 1;
navodila.add(pregled, c);;
}
if(e.getSource() == gumbi[1][2]){
for(int i = 5; i < 15; i++){
for(int j = 5; j < 15; j++){
if(gumbi[i][j].getBackground() == Color.BLACK && gumbi[i][j].getForeground() == Color.WHITE){

}
}
}

gumb.setBackground(Color.WHITE);
}
if (gumb.getBackground() == Color.WHITE && gumb.getForeground() == Color.RED) {
Start.a += 1;
gumbi[0][0].setText("" + Start.a);
} else if (gumb.getBackground() == Color.BLACK && gumb.getForeground() == Color.RED) {

gumbi[0][0].setText("" + Start.a);
if(Start.a == 0){

}
}
cestitke.add(bravo);
cestitke.setVisible(true);
cestitke.setSize(100, 100);
}
}
if (gumb.getBackground() == Color.BLACK && gumb.getForeground() == Color.WHITE) {

gumbi[0][0].setText("" + Start.a);
} else if (gumb.getBackground() == Color.WHITE && gumb.getForeground() == Color.WHITE) {

gumbi[0][0].setText("" + Start.a);
if(Start.a == 0){
for(int i = 5; i < 15; i++){
for (int j = 5; j < 15; j++){
gumbi[i][j].setEnabled(false);
}
}
cestitke.add(bravo);
cestitke.setVisible(true);
cestitke.setSize(100, 100);
}
}
}
}
thanks for your time.
