奇妙日常
2015-03-31 21:40
我就学了前两季,实在是不知道要怎么搞了,谁可以告诉我怎么把数据保存然后在用么Orz!!(不管如何我都做不到让车的类型在账单中显示)
显示车类及价目表我是借鉴了别人的方法的.......主要是我自己弄的那个在容量那接不上.......
求指导Orz
车的父类
package com.imooc; public class Car { //序号 private int num; public int getNum() { return num; } public void setNum(int num) { this.num = num; } //汽车的类型 private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } //租金 private double price; public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } }
载人汽车类
package com.imooc; public class Salooncar extends Car implements ISeat { //载人数量(座位) private int seat; @Override public int getSeat(){ // TODO Auto-generated method stub return seat; } public void setSeat(int newSeat) { this.seat = newSeat; } //构造初始化 public Salooncar(int newNum,String newName,double newPrice ,int newSeat) { this.setNum(newNum); this.setName(newName); this.setPrice(newPrice); this.seat =newSeat; } }
皮卡车类
package com.imooc; public class Pickup extends Car implements ISeat,IBurden{ //载人数量(座位) private int seat; @Override public int getSeat() { return seat; } public void setSeat(int newSeat) { this.seat = newSeat; } //载货量 private double burden; @Override public double getBurden() { return burden; } public void setBurden(double newSurden) { this.burden = newSurden; } //构造初始化 public Pickup(int newNum,String newName,double newPrice,int newSeat,double newSurden){ this.setNum(newNum); this.setName(newName); this.setPrice(newPrice); this.seat = newSeat; this.burden = newSurden; } }
货车类
package com.imooc; public class Wagon extends Car implements IBurden { //载货量 private double burden; @Override public double getBurden() { return burden; } public void setBurden(double newBurden) { this.burden = newBurden; } //构造初始化 public Wagon(int newNum,String newName,double newPrice,double newBurden){ this.setNum(newNum); this.setName(newName); this.setPrice(newPrice); this.burden = newBurden; } }
座位(载人数人数)的接口
package com.imooc; public interface ISeat { public int getSeat(); }
载货量的接口
package com.imooc; public interface IBurden { public double getBurden(); }
主函数
