Answer 2

您可以使用MouseListener接口的类，或者它是有用的抽象实现，MouseAdapter：

public class MyMouseListener extends MouseAdapter { 
    private boolean pressed = false; 

    public void mousePressed(MouseEvent e) { 
     this.pressed = true; 
    } 

    public void mouseReleased(MouseEvent e) { 
     this.pressed = false; 
    } 

    public boolean isPressed() { 
     return pressed; 
    } 
}
