2、目標對象的狀態(tài)發(fā)生改變或做出某種行為時，正在觀察該目標對象的觀察者們將自動地、連鎖地作出相應(yīng)的響應(yīng)行為。 通過本次實驗了解觀察者模式的原理。并能夠運用觀察者模式來進行編程。實驗內(nèi)容1 UML類圖迭代器模式：組合模式：外觀模式?jīng)_茶2 程序的源代碼 迭代器： package Iterator;import java.util.Enumeration;public class MyEnumeration private Enumeration me;private int step;public Enumeration getMe() return me;public void setMe(Enum
