问题描述:
使用抽象工厂模式,完成下述产品等级结构:
类图:
Java代码:
抽象工厂类——AbstractFactory类: package com.shiyan4; public interface AbstractFactory { public Man produceMan(); public Woman produceWoman(); } 具体工厂类——YellowFactory类: public class YellowFactory implements AbstractFactory{ public Man produceMan() { return new YellowMan(); } public Woman produceWoman() { return new YellowWoman(); } } 具体工厂类——BlackFactory类: public class BlackFactory implements AbstractFactory{ public Man produceMan() { return new BlackMan(); } public Woman produceWoman() { return new BlackWoman(); } } 具体工厂类——WhiteFactory类: public class WhiteFactory implements AbstractFactory{ public Man produceMan() { return new WhiteMan(); } public Woman produceWoman() { return new WWoman(); } } 抽象产品类——Man类: public interface Man { public void show(); } 抽象产品类——Woman类: public interface Woman { public void show(); } 具体产品类——YellowMan类: public class YellowMan implements Man{ public void show() { System.out.println("黄皮肤的男性"); } } 具体产品类——BlackMan类: public class BlackMan implements Man{ public void show() { System.out.println("黑皮肤的男性"); } } 具体产品类——WhiteMan类: public class WhiteMan implements Man{ public void show() { System.out.println("白皮肤的男性"); } } 具体产品类——YellowWoman类: public class YellowWoman implements Woman { public void show() { System.out.println("黄皮肤的女性"); } } 具体产品类——BlackWoman类: public class BlackWoman implements Woman { public void show() { System.out.println("黑皮肤的女性"); } } 具体产品类——WhiteWoman类: public class WhiteWoman implements Woman { public void show() { System.out.println("白皮肤的女性"); } } 测试类——Main类: public class main { public static void main(String args[]) { try { AbstractFactory fac; Man m; Woman w; fac=new WhiteFactory(); m=fac.produceMan(); m.show(); w=fac.produceWoman(); w.show(); } catch(Exception e) { System.out.println(e.getMessage()); } } }
运行结果:
