2简单工厂实现(静态工厂)-java

package com.mfz.factory;

//接口设计
public interface Car {
    void run();
}

//接口实现者
package com.mfz.factory;

public class Audi implements Car {
    @Override
    public void run() {
        System.out.println("奥迪再跑");
    }
}


//接收实现者
package com.mfz.factory;

public class Byd implements Car {
    @Override
    public void run() {
        System.out.println("比亚迪再跑");
    }
}

//工厂类
package com.mfz.factory;

public class CarSimpleFactory {

    public  static Car makeCar(String type){
        switch (type){
            case "奥迪":{
                return new Audi();
            }
            case "比亚迪":{
                return new Byd();
            }
            default:{
                return null;
            }
        }
    }
}

package com.mfz.factory;

public class CarSimpleFactory2 {

    public static Car Audi(){
        return new Audi();
    }

    public static Car Byd(){
        return new Byd();
    }
}


//调用者
package com.mfz.factory;

public class Client {

    public static void main(String[] args){

        Car audi = CarSimpleFactory.makeCar("奥迪");
        Car byd = CarSimpleFactory.makeCar("比亚迪");
