java %= java自行车

属性:轮子个数,轮子颜色
行为:跑(输出语句模拟:”瞪着跑”,输出语句中要有自行车的属性)
电动车类:
属性:轮子个数,轮子颜色,电池(布尔类型:真代表有电,假代表没电)
行为:跑(如果电池有电就骑着跑,如果电池没电只能瞪着跑)
注意:骑着跑用输出语句模拟,瞪着跑需要调用自行车类的跑方法

package kehouzuoye.zuoye04;

public  class Bicycle {
    public String getWheel() {
        return wheel;
    }

    public void setWheel(String wheel) {
        this.wheel = wheel;
    }

    public  String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }
        // 属性:轮子个数,轮子颜色
        //      行为:跑(输出语句模拟:”瞪着跑”,输出语句中要有自行车的属性)
        //  电动车类:
        //      属性:轮子个数,轮子颜色,电池(布尔类型:真代表有电,假代表没电)
        //      行为:跑(如果电池有电就骑着跑,如果电池没电只能瞪着跑)
        //      注意:骑着跑用输出语句模拟,瞪着跑需要调用自行车类的跑方法
    private String wheel;
    private String color;
    public void go(){
        System.out.println("蹬着"+this.getWheel()+"轮子的"+this.getColor()+"的车");
    }
}

上面是自行车类

package kehouzuoye.zuoye04;

public class ElectricVehicle extends Bicycle{
    private boolean battery;
    public void run() {
        if(battery==true){
            System.out.println("骑着"+this.getWheel()+"轮子的"+this.getColor()+"的车");
        }else{
            go();
        }
    }
    public boolean isBattery() {
        return battery;
    }
    public void setBattery(boolean battery) {
        this.battery = battery;
    }
}

上面是电动车类
下面是测试类

package kehouzuoye.zuoye04;
public class Test{
    public static void main(String[] args) {
        ElectricVehicle electricVehicle = new ElectricVehicle();
        System.out.println("没电了");
        electricVehicle.setColor("白色");
        electricVehicle.setWheel("2个");
        electricVehicle.setBattery(false);
        electricVehicle.run();
        Bicycle bicycle=(Bicycle) electricVehicle;
        bicycle.setColor("黑色");
        bicycle.setWheel("2个");
        System.out.println("电充好了");
        electricVehicle.setBattery(true);
        electricVehicle.run();

    }
}
