所以我正在制作一个有3个难度的游戏：
在专家级别中，我想在60秒后关闭JFrame，无论是点击按钮开始还是任何其他方式，都不需要花哨。我已经尝试了很多方法，但我保持 得到我想要的东西。
这是我的代码：
package battleship;
import static battleship.Countdown.interval;
import static battleship.Countdown.timer;
import java.util.Timer;
import java.util.TimerTask;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GridBagLayout;
import java.awt.Image;
import java.awt.Toolkit;
import java.io.IOException;
import java.util.Scanner;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JToggleButton;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class Test {
static int interval;
static Timer timer;
public static void main(String[] args) {
new Test();
Scanner sc = new Scanner(System.in);
System.out.print("Input seconds => : ");
String secs = sc.nextLine();
int delay = 1000;
int period = 1000;
timer = new Timer();
interval = Integer.parseInt(secs);
System.out.println(secs);
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
System.out.println(setInterval());
}
}, delay, period);
}
private void setIcon1() {
setIconImage(Toolkit.getDefaultToolkit().getImage(getClass().getResource("ramboo.png")));
}
public Test() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
setInterval();
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new JFrame("BATALLA NAVAL - NIVEL PRINCIPIANTE" );
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.getContentPane().setPreferredSize(new Dimension(900, 700));
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
void setVisible(boolean b) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
private void setIconImage(Image image) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
public class TestPane extends JPanel {
public TestPane() {
try {
for (int i=0; i<=1; i++){
add(crearespacios());
}
for (int i=0; i<=1; i++){
add(crearbombas());
}
//agregar frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
catch (IOException exp) {
exp.printStackTrace();
}
}
protected JToggleButton crearbombas() throws IOException {
JToggleButton btn = new JToggleButton();
btn.setModel(new StickyModel());
btn.setIcon(new ImageIcon(ImageIO.read(getClass().getResource("botondefault.png"))));
btn.setSelectedIcon(new ImageIcon(ImageIO.read(getClass().getResource("bombaa.png"))));
return btn;
}
protected JToggleButton crearespacios() throws IOException {
JToggleButton btn = new JToggleButton();
btn.setModel(new StickyModel());
btn.setBounds(5, 5, 50, 50);
btn.setIcon(new ImageIcon(ImageIO.read(getClass().getResource("botondefault.png"))));
btn.setSelectedIcon(new ImageIcon(ImageIO.read(getClass().getResource("botondefault.png"))));
return btn;
}
protected JButton Instructions() throws IOException {
JButton btnX = new JButton();
btnX.setModel(new StickyModel());
btnX.setIcon(new ImageIcon(ImageIO.read(getClass().getResource("rambofinal.png"))));
btnX.setSelectedIcon(new ImageIcon(ImageIO.read(getClass().getResource("rambofinal.png"))));
return btnX;
}
protected JTextField Instrucciones() throws IOException {
JTextField jtxt = new JTextField();
JTextField jtxt2 = new JTextField();
jtxt.setText("Existen 18 espacios, 5 barcos ocupan 6 de ellos.");
jtxt2.setText("Tenes 16 clicks.");
return jtxt;
}
}
private static final int setInterval() {
if (interval == 1)
timer.cancel();
return --interval;
}
public class StickyModel extends JToggleButton.ToggleButtonModel {
public void reset() {
super.setSelected(false);
}
@Override
public void setSelected(boolean b) {
if (!isSelected()) {
super.setSelected(b);
}
}
}
}
在这里尝试使用System.exit(0)和System.runfinalization;，但它只显示了＆＃34;控制台输出（？）＆＃34;而不是框架
没有计时器：

}
}
public class StickyModel extends JToggleButton.ToggleButtonModel {
public void reset() {
super.setSelected(false);
}
@Override
public void setSelected(boolean b) {
if (!isSelected()) {
super.setSelected(b);
}
}
}
}
顺便说一句......游戏是战舰，我在该代码中创建了一个自定义按钮，这就是为什么我需要与按钮在同一个Frame.java中的计时器。
