哒哒租车系统

Cars类为父类

重写Cars类toString方法

三种车型3个子类继承父类

Cars.java

package com.xk;

public class Cars \{

public int id;

public String name;

public float price;

public float carryingCapacity;

public int seatingCapacity;

@Override

public String toString() \{

if(seatingCapacity==0) \{

return id+".\\t"+name+"\\t"+price+"元/天\\t载货"+carryingCapacity+"吨";

\}else if(carryingCapacity==0)\{

return id+".\\t"+name+"\\t"+price+"元/天\\t载客"+seatingCapacity+"人";

\}else\{

return id+".\\t"+name+"\\t"+price+"元/天\\t载货"+carryingCapacity+"吨\\t载客"+seatingCapacity+"人";

Truck.java

package com.xk;

public class Truck extends Cars\{
