lass Car{
private String brand;//品牌
private String type;//颜色
private String money;//价格

//空参

public  Car(){
	System.out.println("无参方法被调用");
}
//重写构造函数

public Car(String b,String t,String m){
this.brand = b;
this.type = t;
this.money = m;
}

//显示信息

public void show(){
System.out.println("品牌为："+this.brand+" 颜色为："+this.type+"尺寸为："+this.money);
     }
public void run(){
System.out.println("汽车跑了");
     }
}

//测试类

public class QIChe {
public static void main(String[] args){
Car c = new Car("BugattiChiron","红色","3000K $");//初始化信息
