JAVA小练习7

代码如下：
public interface Car {
void speak();

void start();

void run();

void stop();

}

代码如下：
public class Driver {
class Benz implements Car {
private String model;
private double price;
private String color;

    public String getModel() {
        return model;
    }

    public void setModel(String model) {
        this.model = model;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    @Override
    public void start() {
        System.out.println("奔驰[" + model + "]起步");
    }

    @Override
    public void run() {
        System.out.println("奔驰[" + model + "]行驶");
    }

    @Override
    public void stop() {
        System.out.println("奔驰[" + model + "]停止");
    }
    
    public void speak() {
        System.out.println(color + "色奔驰[" + model + "]单价：" + price +"万~");
    }
}

}
