2、類是觀察該目標的觀察者們。正因為該模式是基于“一對多”的關(guān)系，所以該模式一般是應(yīng)用于由一個目標對象和 N 個觀察者對象組成（當然也可以擴展為有多個目標對象，但我們現(xiàn)在只討論前者）的場合。當目標對象的狀態(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 代理模式-追女友實例： 適配器模式-清潔系統(tǒng)： 遠程方法調(diào)用： 2 程序的源代碼 代理模式-追女友實例： package Gift; public interface GiveGift public void G
