這篇文章主要介紹了java設計模式之簡單工廠模式的相關資料，具有一定的參考價值，有興趣的小夥伴們可以參考一下
簡單工廠模式：由一個工廠物件決定建立出哪一種類別的實例。
1.抽象類別
public abstract class People {
public abstract void doSth();
}#2.具體類別
public class Man extends People{
@Override
public void doSth() {
System.out.println("I'm a man,I'm coding.");
}
}3.具體類別
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,"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");
Objects.requireNonNull(foodie,"对象不存在");
foodie.doSth();
}
