MouseEvent

MouseListener
mousePressed()
mouseReleased()
mouseEntered()
mouseExited()
mouseClicked()

MouseMotionListener
mouseDragged()
mouseMoved()

ActionEvent

ActionListener

假设一个event source注册有以上3个listener，且产生了MouseEvent和ActionEvent，它怎么知道MouseListener、MouseMotionListener和ActionListener有那些方法？

具体地，当发生mouse pressed，它怎么知道要调用的是MouseListener的mousePressed()方法，而不是MouseMotionListener的，更不是ActionListener的？

如果我创建新的event怎么办？
