线程中断和ActionListener Java

我有一个函数graphics（），它创建我的JFrame和两个JRadioButton，并向它们添加ActionListener。此图形从main（）调用，图形本身调用game（）

在文本区域显示“这是私有信息”后，我希望程序执行暂停40秒，或者直到用户按下JRadioButton，以较早者为准。所以我添加了一个ActionListener，并在其中调用了t.interrupt（）

private void jRadioButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     t.interrupt();
    jRadioButton1.setVisible(false);
    jRadioButton2.setVisible(false);
    //System.out.println(t.interrupted());
    jTextArea1.setText("Please wait...");

    }

但是，即使在选择了应该触发中断的JRadioButton之后，也不会发生这种情况，并且t.interrupted返回false

任何帮助都将不胜感激。

永远不要调用Swing事件线程上的

线程。睡眠（…）

，因为您将冻结线程并有效地冻结程序。解决方案是考虑使用摆动定时器来满足您的需求的时间依赖部分，并使用SelectionListener作为JCHECKBOX或JRADIONButt需求。 例如：

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;

import javax.swing.*;

public class PausingExecution extends JPanel {
   private static final String SELECTED_TEXT = "Snafus are Better!!!";
   private static final String UNSELECTED_TEXT = "Fubars Rule!!";
   private static final String TIMES_UP = "Time's Up!!!!";
   private static final int TIMER_DELAY = 10 * 1000;

   private JTextField messageField = new JTextField(UNSELECTED_TEXT, 10);
   private JCheckBox checkBox = new JCheckBox("Click Me");

   public PausingExecution() {
      add(messageField);
      add(checkBox);

      checkBox.addItemListener(new ItemListener() {

         @Override
         public void itemStateChanged(ItemEvent iEvt) {
            if (iEvt.getStateChange() == ItemEvent.SELECTED) {
               messageField.setText(SELECTED_TEXT);
            } else {
               messageField.setText(UNSELECTED_TEXT);
            }
         }
      });

      Timer mySwingTimer = new Timer(TIMER_DELAY, new ActionListener() {

         @Override
         public void actionPerformed(ActionEvent e) {
            messageField.setText(TIMES_UP);
            checkBox.setEnabled(false);
         }
      });

      mySwingTimer.setRepeats(false);
      mySwingTimer.start();
   }

   private static void createAndShowGui() {
      PausingExecution mainPanel = new PausingExecution();

      JFrame frame = new JFrame("PausingExecution");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}
