工厂模式

应用场景：例如一辆车，有不同的品牌，每个品牌代表一个工厂，这就是典型的工厂模式。

代码：

public interface Car{
    public void start();
    public void stop();
}

 

public class BaseCar implements Car{
    private int maxSpeed;
    private String name;
    
    public void setMaxSpeed(int maxSpeed) {
        this.maxSpeed = maxSpeed;
    }
    public int getMaxSpeed(){
        return this.maxSpeed;
    }

    public void setName(String name) {
        this.name = name
    }
    public String getName() {
        return this.name;
    }

    public void start() {
        //TODO
    }

    public void stop() {
        //TODO
    }
}

 

public class Audi extends BaseCar {
 
    @Override
    public void start() {
        System.out.println("启动，name=" + this.getName() + ",speed=" + this.getMaxSpeed());
    }
    @Override
    puvlic void stop() {
       System.out.println("停止，name=" + this.getName() + ",speed=" + this.getMaxSpeed());
    }
}
