设计模式之工厂模式 Factory实现

simpleFactory

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

//两个实现类
public class Audi implements Car{

    public void run() {
        System.out.println("奥迪在跑");
    }
    
}

public class Byd implements Car{

    public void run() {
        System.out.println("Byd在跑");
    }
    
}
