Java Swing中使用双击事件

今天自己写个小程序碰到了这个问题，在网上搜了一下人家的思路，整理了一下代码可以运行，感觉不错！
直接在JBuilder中新建一个应用程序，至于具体步骤就不描述了，此代码没有main函数无法直接运行。下面我贴出在Frame1中的代码：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;
import java.util.Date;

public class Frame1
    extends JFrame {
  JPanel contentPane;
  BorderLayout borderLayout1 = new BorderLayout();
  JPanel jPanel1 = new JPanel();
  XYLayout xYLayout1 = new XYLayout();
  JScrollPane jScrollPane1 = new JScrollPane();
  JList jList1 = new JList();
 //初始化的JList中的数据
  String[] strData = {
      "One", "Tow", "Three"};
 //保存点击按钮的时间
  long clickTime = 0;

  //Construct the frame
  public Frame1() {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);
    try {
      jbInit();
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }

  //Component initialization
  private void jbInit() throws Exception {
    contentPane = (JPanel)this.getContentPane();
    contentPane.setLayout(borderLayout1);
    this.setSize(new Dimension(532, 468));
    this.setTitle("Frame Title");

    jPanel1.setLayout(xYLayout1);
    jList1.addMouseListener(new Frame1_jList1_mouseAdapter(this));
    contentPane.add(jPanel1, BorderLayout.CENTER);
    jPanel1.add(jScrollPane1, new XYConstraints(18, 34, 209, 326));
    jScrollPane1.getViewport().add(jList1, null);
    jList1.setListData(strData);
  }

  //Overridden so we can exit when window is closed
  protected void processWindowEvent(WindowEvent e) {
    super.processWindowEvent(e);
    if (e.getID() == WindowEvent.WINDOW_CLOSING) {
      System.exit(0);
    }
  }

//具体实现按钮双击的功能的方法，  很简单的算法，不做解释了
public boolean checkClickTime() {
    long nowTime = (new Date()).getTime();

    if ( (nowTime - clickTime) < 300) {
      clickTime = nowTime;
      return true;
    }
    clickTime = nowTime;
    return false;

  }

  void jList1_mouseReleased(MouseEvent e) {
    //判断是否双击，是的话写你要实现的功能
     if (checkClickTime()) {
      System.out.println("Click Double");

    }
  }
}

class Frame1_jList1_mouseAdapter
    extends java.awt.event.MouseAdapter {
  Frame1 adaptee;

  Frame1_jList1_mouseAdapter(Frame1 adaptee) {
    this.adaptee = adaptee;
  }

  public void mouseReleased(MouseEvent e) {
    adaptee.jList1_mouseReleased(e);
  }
}
