java第二季的达达租车软件模拟

标签：
Java 产品

花了一晚上，和大家比较后发现我的方法太复杂，，分别构造了一堆子类。
不过效果基本上达到了要求。
抽象类Cars

package com.projectrent;

public abstract class Cars {
    protected int rent=0;
    protected String name="";
    protected int num=0;
    protected boolean forMan=false;
    protected int numOfPassengers;
    protected boolean forGoods=false;
    protected int tonsOfGoods;
    protected int totalRent;
    protected int totalNumOfPassengers;
    protected int totalTonsOfGoods;
    public abstract void setRent();
    public abstract void setName();
    public abstract void setNum();
    public abstract void display();
    public abstract void dispARentInfo(int[] nums,int[] days);
}

Car1
