java小程序中鼠标事件的响应处理

如何在小程序中实现鼠标响应？

public class MyMouseListener extends MouseAdapter {    public void mouseClicked(MouseEvent evt) {        if (evt.getClickCount() == 3) {        // 处理鼠标三击        } else if (evt.getClickCount() == 2) {        // 处理鼠标双击        }    }} 处理鼠标右键 public mouseClicked(MouseEvent e){     if(e.isMetaDown()){           //检测鼠标右键单击     } }public class MyMouseListener extends MouseAdapter {    public void mouseClicked(MouseEvent evt) {        if ((evt.getModifiers() & InputEvent.BUTTON1_MASK) != 0) {            processLeft(evt.getPoint());            //处理鼠标左键单击        }        if ((evt.getModifiers() & InputEvent.BUTTON2_MASK) != 0) {            processMiddle(evt.getPoint());            //处理鼠标中间键单击        }        if ((evt.getModifiers() & InputEvent.BUTTON3_MASK) != 0) {            processRight(evt.getPoint());            //处理鼠标右键单击        }    }} ?
