The example in this article briefly describes the Java List double-click event implementation method, which has good reference value. Share it with everyone for your reference. The specific method is as follows:

1. Define a MouseListener;

2. Add mouseClicked event in mouseListener;

3. Obtain the List object from MouseEvent's getSource();

4. Obtain the Index of the clicked item from the getSelectedIndex() event of List;

5. According to the Index, use the getItem() method of List to obtain the clicked item;

6. Finally, use addMouseListener() to add the defined MouseListener to the List.

// 双击鼠标事件
MouseListener mouseListener = new MouseAdapter() {
   public void mouseClicked(MouseEvent mouseEvent) {
 List theList = (List) mouseEvent.getSource();
 if (mouseEvent.getClickCount() == 2) {
   int index = theList.getSelectedIndex();
   if (index >= 0) {
  String s = theList.getItem(index);
   }
 }
   }
};
lstRoster.addMouseListener(mouseListener);

I hope this article will be helpful to everyone’s Java programming.
