package ddd;/**/
/* Represents an air Wing */
/**/public class Wing extends AirUnit{public static final String FEATURES A Wing with 216 aircrafts;Airforce[] fighters new Airforce[162];Airforce[] bombers new Airforce[18];Airforce[] transporters new Airforce[18];Airforce[] eAircrafts new Airforce[18];public Wing(){for(int k0;k162;k){fighters[k] new F22();super.attach(fighters[k]);// need 162 fighters}for(int k0;k18;k){bombers[k] new B52();super.attach(bombers[k] );// need 18 bombers}for(int k0;k18;k){transporters[k] new C130J();super.attach(transporters[k]);// need 18 transporters}for(int k0;k18;k){eAircrafts[k] new E9A();super.attach(eAircrafts[k]);// need 18 eAirplanes}}public String getDescription(){return FEATURES;}public String fight(){return super.fight();}
}2、添加GUI:红色部分是添加进去的

}【运行截图】 【实验小结】 通过本次实验学会了使用组合器方法模式。组合器方法模式的适用性如下 我们这样来简单的理解组合模式组合模式就是把一些现有的对象或者元素,经过组合后组成新的对象新的对象提供内部方法,可以让我们很方便的完成这些元素或者内部对象的访问和操作。我们也可以把组合对象理解成一个容器,容器提供各种访问其内部对象或者元素的API我们只需要使用这些方法就可以操作它了。
