簡單工廠模式：由一個工廠對象決定創建出哪一種類的實例。
1.抽象類
public abstract class People { public abstract void doSth();}2.具體類
public class Man extends People{ @Override public void doSth() { System.out.println("I'm a man,I'm coding."); }}3.具體類
public class Girl extends People{ @Override public void doSth() { System.out.println("I'm a girl,I'm eating."); }}4.工廠
public class PeopleFactory { public static People getSpecificPeople(String type){ if("A-Man".equals(type)){ return new Man(); }else if("B-Girl".equals(type)){ return new Girl(); }else { return null; } }}5.測試代碼
public class PeopleTestDemo { public static void main(String[] args) { People man = PeopleFactory.getSpecificPeople("A-Man"); Objects.requireNonNull(man,"對象不存在."); man.doSth(); People girl = PeopleFactory.getSpecificPeople("B-Girl"); Objects.requireNonNull(girl,"對象不存在"); girl.doSth(); People foodie = PeopleFactory.getSpecificPeople("Foodie"); Objects.requireNonNull(foodie,"對象不存在"); foodie.doSth(); }}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VeVb武林網。
