java学习第二季租赁系统

程序大体分三块：
车辆类、显示类、租赁类
租赁类（具体运行）：
`package com.carrent;

import java.util.Scanner;

public class Rent {
private static Scanner input;
private static int s,m,n ;
public static void main(String[] args) {
// TODO Auto-generated method stub
input=new Scanner(System.in);
System.out.println("是否希望开始租赁选择：是则输入1,否则输入2:");
if(input.nextInt()==1){
Carlist aCarList =new Carlist();
aCarList.sort();//库存展示

            //类型选择
            System.out.println("请选择想要租赁的车型编号：");
            s = input.nextInt();
            switch (s) {
            case 1:
                System.out.println("您选择的是"+aCarList.carlists[0].getBrand()+"汽车");
                break;
            case 2:
                System.out.println("您选择的是"+aCarList.carlists[1].getBrand()+"重型货车");
                break;
            case 3:
                System.out.println("您选择的是"+aCarList.carlists[2].getBrand()+"轻型货车");
                break;
            case 4:
                System.out.println("您选择的是"+aCarList.carlists[3].getBrand()+"皮卡车");
                break;
            case 5:
                System.out.println("您选择的是"+aCarList.carlists[4].getBrand()+"轿车");
                break;

            default:
                System.out.println("类型名不存在，出错。");
                break;
            }
            System.out.println("请输入租赁数量：");
            m = input.nextInt();
            System.out.println("请输入租赁时间：(单位/天)");
            n = input.nextInt();
            System.out.println("是否确定租赁，是则输入1，否则0.");
            if (input.nextInt()==1) {
                YourRent[] your = {
                        new YourRent(aCarList,m,n,s-1)
                };
                System.out.println("您的租赁列表如下：");
                System.out.println("\t型号"+"\t品牌"+"\t载货重"+"\t载客量"+"\t日租赁价格"+"\t待租数量"+"\t租赁时间");
                for (YourRent x:your) {
                    x.show();
                }
            }else {

            }
            System.out.println("是否结束租赁系统：1表示继续租赁，0表示退出.");  
            System.exit(input.nextInt());
        }
}

}
车辆父类：
package com.carrent;

public class Car {
private String name="车";
private String brand;
private int burden ;
private int busload;
private int price;
private int num;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public int getBurden() {
return burden;
}
public void setBurden(int burden) {
this.burden = burden;
}
public int getBusload() {
return busload;
}
public void setBusload(int busload) {
this.busload = busload;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
}
子类，轿车、公交、小货车、大卡车、皮卡：
轿车子类：
package com.carrent;

public class Sedan extends Car {

public Sedan(String aBrand, int aburden, int abusload, int aprice,int anum) {
    this.setName("轿车");
    this.setBrand(aBrand);
    this.setBurden(aburden);
    this.setBusload(abusload);
    this.setPrice(aprice);
    this.setNum(anum);
}

}
公交子类：
package com.carrent;

public class Bus extends Car {

public Bus(String aBrand, int aburden, int abusload, int aprice,int anum) {
    this.setName("公交");
    this.setBrand(aBrand);
    this.setBurden(aburden);
    this.setBusload(abusload);
    this.setPrice(aprice);
    this.setNum(anum);
}

}
小货车：
package com.carrent;

public class LightTruck extends Car {

public LightTruck(String aBrand, int aburden, int abusload, int aprice,int anum) {
    this.setName("轻型货车");
    this.setBrand(aBrand);
    this.setBurden(aburden);
    this.setBusload(abusload);
    this.setPrice(aprice);
    this.setNum(anum);
}

}
大卡车：
package com.carrent;

public class HeavyTruck extends Car {

public HeavyTruck(String aBrand, int aburden, int abusload, int aprice,int anum) {
    this.setName("重型货车");
    this.setBrand(aBrand);
    this.setBurden(aburden);
    this.setBusload(abusload);
    this.setPrice(aprice);
    this.setNum(anum);
}

}
皮卡子类：
package com.carrent;

public class PickUp extends Car{

public PickUp(String aBrand, int aburden, int abusload, int aprice,int anum) {
    this.setName("皮卡");
    this.setBrand(aBrand);
    this.setBurden(aburden);
    this.setBusload(abusload);
    this.setPrice(aprice);
    this.setNum(anum);
}

}
列表显示类，库存列表，客户租赁表：
库存显示类：
package com.carrent;

public class Carlist {
Car[] carlists ={
new Bus("YUTONG",0,24,3500,12),new HeavyTruck("解放",20,2,5000,5),
new LightTruck("长安之星", 4, 2, 2000,6),
new PickUp("Ford福特", 3, 5, 3000,7),new Sedan("大众", 0, 5,2000,2)
};
public void sort(){
System.out.println("待租车辆列表：");
System.out.println("\t型号"+"\t品牌"+"\t载货重"+"\t载客量"+"\t日租赁价格"+"\t待租数量");
int i = 1;
for(Car x:carlists)
{
System.out.print(i+".\t"+x.getName());
System.out.print("\t"+x.getBrand());
System.out.print("\t"+x.getBurden()+"吨");
System.out.print("\t"+x.getBusload()+"人");
System.out.print("\t"+x.getPrice()+"$");
System.out.println("\t"+x.getNum()+"辆");
i++;
}
}
}
客户租赁类：
package com.carrent;
/*

• 个人租赁列表
  */
  public class YourRent {
  String name;
  String brand;
  int burden ;
  int busload;
  int price;
  int rentNum;
  int rentDay;
  public YourRent(Carlist a,int x,int y,int z) {
  // TODO Auto-generated constructor stub
  //aCarList.carlists[0].brand;
  name = a.carlists[z].getName();
  brand = a.carlists[z].getBrand();
  burden = a.carlists[z].getBurden();
  busload = a.carlists[z].getBusload();
  price = a.carlists[z].getPrice();
  rentNum = x;
  rentDay = y;
  }
  public void show() {
  System.out.print("\t"+this.name);
  System.out.print("\t"+this.brand);
  System.out.print("\t"+this.burden+"吨");
  System.out.print("\t"+this.busload+"人");
  System.out.print("\t"+this.price+"$");
  System.out.print("\t"+this.rentNum+"辆");
  System.out.println("\t"+this.rentDay+"天");
  }
  }
