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.测试代码
public class PeopleTestDemo {
public static void main(String[] args) {
People man = PeopleFactory.getSpecificPeople("A-Man");
Objects.requireNonNull(man,"对象不存在.");
man.doSth();
People girl = PeopleFactory.getSpecificPeople("B-Girl");
Objects.requireNonNull(girl,"对象不存在");
girl.doSth();
People foodie = PeopleFactory.getSpecificPeople("Foodie");
