Java实现答答租车系统
这篇文章主要为大家详细介绍了Java实现答答租车系统，具有一定的参考价值，感兴趣的小伙伴们可以参考一下本文实例为大家分享了java实现答答租车系统的具体代码，供大家参考，具体内容如下
项目需求：
基本界面需求：
and:
最后是把账单打印出来：
个人代码实现
基本思路：考虑到车辆之间的共性，设置一个父类car, 子类mannedcar(载人), truck(载货)，bothcary(既载人又载货)，三者继承父类car的price, name属性, getname()方法, 同时重写getpersonnum, getgoodsnum方法。
car.java:
package car;
public abstract class car {
protected int price;
protected string name;
protected int getprice() {
return price;
}
protected string getname() {
return name;
}
public int getpersonnum() {
// todo auto-generated method stub
return 0;
}
public int getgoodsnum() {
// todo auto-generated method stub
return 0;
}
}
mannedcar.java:
package car;
public class mannedcar extends car {
private int personnum;
public mannedcar() {
this.personnum = 0;
this.price = 0;
this.name = "";
}
public mannedcar(int personnum, int price, string name) {
this.personnum = personnum;
this.price = price;
this.name = name;
}
@override
public int getpersonnum() {
return personnum;
}
}
truck.java:
package car;
public class truck extends car{
private int goodsnum;
public truck() {
this.price = 0;
this.goodsnum = 0;
this.name = "";
}
public truck(int price, int goodsnum, string name) {
this.price = price;
this.goodsnum = goodsnum;
this.name = name;
}
@override
public int getgoodsnum() {
return goodsnum;
}
}
bothcarry.java:
package car;
public class bothcarry extends car {
private int personnum;
private int goodsnum;
public bothcarry() {
this.personnum = 0;
this.goodsnum = 0;
this.name = "";
this.price = 0;
}
public bothcarry(int price, int personnum,
int goodsnum, string name) {
this.personnum = personnum;
this.goodsnum = goodsnum;
this.price = price;
this.name = name;
}
public int getpersonnum() {
return personnum;
}
public int getgoodsnum() {
return goodsnum;
}
}
系统：
carsystem.java:
package car;
import java.util.scanner;
import java.util.arraylist;
public class carsystem {
private static string goodbyeinfo = "欢迎再次使用本系统，再见！";
private static int dayborrow;
public static void beginsystem() {
carsystem.systemwelcome();
scanner scanner = new scanner(system.in);
string usercommand = scanner.next();
switch(usercommand){
case "1":
carsystem.getuserinput();
break;
case "0":
system.out.println(goodbyeinfo);
break;
default:
system.out.println("输入错误..end running..");
system.exit(0);
break;
}
}
public static void systemwelcome() {
system.out.println("欢迎使用答答租车系统:");
system.out.println("您是否要租车: 1-是 0-否");
}
public static void getuserinput() {
int numcarborrow = 0;
arraylist<car> carlist = new arraylist<car>(6);
carlist.add(new mannedcar(4,500,"奥迪a4"));
carlist.add(new mannedcar(4,400,"马自达6"));
carlist.add(new bothcarry(450,4,2,"皮卡雪6"));
carlist.add(new mannedcar(20,800,"金龙"));
carlist.add(new truck(400,4,"松花江"));
carlist.add(new truck(1000,20,"依维河"));
system.out.println("请输入您要租汽车的数量:");
scanner sr = new scanner(system.in);
numcarborrow = sr.nextint();
int[] carnumlist = new int;
for(int i=0;i<numcarborrow;i++) {
system.out.println("请输入第" + (i+1) + "辆车的序号:");
if (sr.hasnext()) {
carnumlist = sr.nextint();
}
}
system.out.println("请输入租车天数:");
if (sr.hasnext()) {
dayborrow = sr.nextint();
}
sr.close();
stringbuilder manned = new stringbuilder();
int numofmanned = 0;
stringbuilder goods = new stringbuilder();
int numofgoods = 0;
int totalcost = 0;
for(int i = 0;i < carnumlist.length;i++) {
if(carnumlist>0 && carnumlist < 3 || carnumlist==4) {
manned.append("");
manned.append(carlist.get(carnumlist-1).getname());
numofmanned += carlist.get(carnumlist-1).getpersonnum();
}
else if(carnumlist==3) {
manned.append("");
manned.append(carlist.get(carnumlist-1).getname());
goods.append("");
goods.append(carlist.get(carnumlist-1).getname());
numofmanned += carlist.get(carnumlist-1).getpersonnum();
numofgoods += carlist.get(carnumlist-1).getgoodsnum();
}
else {
goods.append("");
goods.append(carlist.get(carnumlist-1).getname());
numofgoods += carlist.get(carnumlist-1).getgoodsnum();
}
totalcost += carlist.get(carnumlist-1).getprice();
}
//output
system.out.println("您的账单:\n***可载人的车有:");
system.out.println(manned + "共载人: " + numofmanned);
system.out.println("***载货的车有:\n" + goods + "共载货 : " + numofgoods + "吨");
system.out.println("***租车总价格: " + totalcost * dayborrow + "元");
}
}
主程序:
package car;
public class carsystemtest {
public static void main(string[] args) {
// todo auto-generated method stub
carsystem.beginsystem();
}
}
