汽车租赁系统的实现
一、使用技术
javaSE
二、实现功能
汽车租赁系统
具体要求如下：
使用面向对象的知识实现一个汽车租赁系统
1.汽车租赁信息表如下
2.类和属性
三、运行效果图如下：
1.先创建一个汽车类作为父类，这里有汽车的公共属性：
public class Automobile {
//汽车类
private String licensePlate;//车牌
private String brand;//品牌
private int rent;//租金
public Automobile() {
}
public Automobile(String licensePlate, String brand, int rent) {
this.licensePlate = licensePlate;
this.brand = brand;
this.rent = rent;
}
public String getLicensePlate() {
return licensePlate;
}
public void setLicensePlate(String licensePlate) {
this.licensePlate = licensePlate;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public int getRent() {
return rent;
}
public void setRent(int rent) {
this.rent = rent;
}
}
2.创建一个轿车类，继承汽车类的属性
public class Car extends Automobile{
//轿车
private String model;//型号
public Car(String model) {
this.model = model;
}
public Car(String licensePlate, String brand, int rent, String model) {
super(licensePlate, brand, rent);
this.model = model;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
}
3.创建一个客车类，继承汽车类的属性
public class Passengercar extends Automobile{
//客车
private String seatingCapacity;//座位数
public Passengercar(String seatingCapacity) {
this.seatingCapacity = seatingCapacity;
}
public Passengercar(String licensePlate, String brand, int rent, String seatingCapacity) {
super(licensePlate, brand, rent);
this.seatingCapacity = seatingCapacity;
}
public String getSeatingCapacity() {
return seatingCapacity;
}
public void setSeatingCapacity(String seatingCapacity) {
this.seatingCapacity = seatingCapacity;
}
}
4.创建测试类，用于实现这个系统
import java.util.Scanner;
public class TestAutomobile {
public static void main(String[] args) {
Car c1 = new Car("京NY28588", "宝马X6", 800, "1");
Car c2 = new Car("京CNY3284", "宝马550i", 600, "1");
Car c3 = new Car("京NT37465", "别克林荫大道", 300, "1");
Car c4 = new Car("京NT969968", "别克GL8", 600, "1");
Passengercar p1 = new Passengercar("京6566754", "金杯,16座", 800, "2");
Passengercar p2 = new Passengercar("京8696997", "金龙,16座", 800, "2");
Passengercar p3 = new Passengercar("京9696996", "金杯,34座", 1500, "2");
Passengercar p4 = new Passengercar("京8696998", "金龙，34座", 1500, "2");
Scanner sc = new Scanner(System.in);
System.out.println("***********************欢迎光临秋名山守望者汽车租赁公司***********************");

String a=sc.next();

double a3=sc.nextInt();
System.out.println("分配给您的汽车牌号是："+c2.getLicensePlate());
System.out.print("您需要支付的租赁费用是：");
if (a3>7&&a3<=30){
System.out.println(c2.getRent()*a3*0.9+"元");
}else if(a3>30&&a3<=150){
System.out.println(c2.getRent()*a3*0.8+"元");
