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 Hello extends Applet implements MouseListener{ 

public void init(){
    addMouseListener(this);
}
public void mouseEntered(MouseEvent e){
     au.play();
     setBackground(Color.blue);
} 



public void mouseExited(MouseEvent e){
setBackground(Color.black);
} 

public void mousePressed(MouseEvent e){} 


public void mouseReleased(MouseEvent e){} 



public void mouseClicked(MouseEvent e){} }

 首先在小程序中实现事件监听器，再实现鼠标用户接口
如何小程序中处理鼠标双、三击？

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
        }
    }
}
