大神来看看
public class Bus {//汽车类
int seat;//座位数
float price;
public void showSeat(){
this.seat=47;
System.out.println("Bus的座位数为:"+seat);
}
public Bus(int seat){
System.out.println("父类的构造方法");
this.seat=seat;
}
}public class car extends Bus { //子类轿车类
public void showSeat(){ //方法重写
this.seat=4;
System.out.println("子类car的座位数为"+seat);
System.out.println("父类的Bus的座位数为"+super.seat);
}
public car(int seat){ //带参构造方法
super(seat);
System.out.println("子类的构造方法");
}
}public class test {
public static void main(String[] args){
car honda=new car(55);
honda.showSeat();
}
}问下大神 为什么输出是：
子类car的座位数为4
父类的Bus的座位数为4
我只是在构造方法里面给seat赋了一个值55吧
