车辆二手车java项目，java二手车管理系统怎样收藏车

1，java二手车管理系统怎样收藏车

哈哈哈，给你一个表 uid（用户id），cid（车id）收藏就加一行（前提是是否收藏了此车）当然这是web的解决方案，如果是一个用户的话，就直接在车的表里面加一个列

学到java什么部分了？

2，在瓜子二手车上面买车后他们都提供哪些整备服务呢

瓜子二手车平台对车辆提供深度的全面体检测和车内的健康清洗等多项整备服务，可以说，经过了层层检测的这些车辆，性价比还是很高的。另外，在瓜子二手车平台上购车还可享受2年或4万公里售后保障，30天无忧退等服务。

瓜子二手车已经在200多个城市开设了站点，规模大，发展速度也很快。重点是他们采取的是直卖的形式，个人对个人，中间没有差价，买家可以直接跟买家交易。车辆检测很严格，对买车来说很放心。可以尝试下，完全是过来人对经验之谈。

3，编写一个java应用程序设计一个汽车类Vehile属性有车轮个数

这有什么难得，创建两个类public class Vehile{Double wheels;Double weight; //构造函数，set get方法 } public class Truck extend Vegile{//继承汽车类就好了这里加上Truck类的属性} public class Minibus extend Truck{//面包车继承Truck 添加他的特有属性} 上边两个类自定义一个方法汽车有onDrive（）方法 Truck 继承他自然要重写其onDrive（）方法再添加一个Truck独有的方法名字自己随便取；面包车类继承Truck自然会重写其他两个直接父类和间接父类的方法；再写一个带有main方法的Test测试类，在main方法里new 其中想要测试的对象就可以调用其中的方法和特有属性；

4，JAVA开发一个轿车类Car要求如下

class car { private int carNumber; private String color; public car(){}; public car(String color) { this.color=color; } public car(int carNumber) { this.carNumber=carNumber; } public void setcarNumber(int carNumber) { this.carN

public class car { private static int speed; public car(int speed){ this.speed = speed; } public static int getspeed(){ return speed; } } public class speedexception{ int speed = car.getspeed(); public void speedexception() throws exception{ system.out.println("speed:" + speed); if(speed > 200){ throw new exception("speed大于200"); } } } public class testcar { public static void main(string [] args) throws exception{ car car = new car(300); speedexception sexception = new speedexception(); sexception.speedexception(); } }

5，编写java程序设计一个汽车类

随便给你建了个，代码如下： package com.ask.test; public class Car { //颜色(黑色、白色等) private String color; //品牌(奔驰、宝马、东风等) private String brand; //类型（越野、普通汽车等） private String type; //构造方法 public Car(String color, String brand, String type) { super(); this.color = color; this.brand = brand; this.type = type; } public String getColor() { return color; } public void setColor(String color) { this.color = color; } public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public String getType() { return type; } public void setType(String type) { this.type = type; } }

public class carmanufactory { private string style; private string color; private string category; public carmanufactory(string style, string color, string category) { super(); this.style = style; this.color = color; this.category = category; } public carmanufactory() { super(); // todo auto-generated constructor stub } public string getstyle() { return style; } public string getcolor() { return color; } public string getcategory() { return category; } }

6，急高手请告诉我如何编写小汽车的java程序代码重赏

import java.lang.*; class Car{ public void safe(){ System.out.println("an quan xi shu gao !"); } } class Benz extends Car{ public void safe(){ System.out.println("che hao !"); } } class Santana extends Car{ public void safe(){ System.out.println("che hen bu hao hao !"); } } public class Test{ public static void main(String[]args){ Car s = new Car(); s.safe(); Benz s1 = new Benz(); s1.safe(); Santana s2 = new Santana(); s2.safe(); Car s3 = new Benz(); s3.safe(); Car s4 = new Santana(); s4.safe(); } } 这是一个命名为Test.java public class Car{ double price; String name; int id; //3个重载的构造方法(name)(id,name)(id,name,price) public Car(String name){ this(789,name); } public Car(int id,String name){ this(id,name,100000); } protected Car(int id,String name,double price){ this.price = price; this.name = name; this.id = id; } //3个重载的普通方法drive(int) drive(String) drive(int ,String) public void drive(int i){ System.out.println("i = " + i); System.out.println(price + "\n" + name + "\n" + id); } protected String drive(String s){ return "s is: " + s; } int drive(int i,String s){ return 2007; } } class Test{ public static void main(String[]args){ Car c1 = new Car(777,"Santana"); c1.drive(18); } } 这个命名为Car.java 希望有你要的!

7，用java编写一个程序由车牌号前2位知道车辆所属地浙江省的市就行

import java.util.Scanner; public class CarCard { //浙A 杭州，浙B 宁波，浙C 温州，浙D 绍兴，浙E 湖州，浙F 嘉兴，浙G 金华，浙H 衢州，浙J 台州，浙K 丽水，浙L 舟山 public static void main(String[] args) { System.out.println("请输入车牌号"); Scanner sc = new Scanner(System.in); String carno = sc.next(); String t = carno.substring(0,2); checkAddressByCarCard(t); } private static void checkAddressByCarCard(String no){ String a[]={"浙A","浙B","浙C","浙D","浙E","浙F","浙G","浙H","浙J","浙K","浙L"}; String b[]={"杭州","宁波","温州","绍兴","湖州","嘉兴","金华","衢州","台州","丽水","舟山"}; int index = 0; for(int i = 0;i<11;i++){ if(no.equalsIgnoreCase(a[i])){ index=i; System.out.println("车辆所在地为："+b[i]); } } } }

package demo; import java.util.Scanner; public class CarCard { //浙A 杭州，浙B 宁波，浙C 温州，浙D 绍兴，浙E 湖州，浙F 嘉兴，浙G 金华，浙H 衢州，浙J 台州，浙K 丽水，浙L 舟山 //网上搜的，应该是对的，这个东西应该管你要 public static void main(String[] args) { System.out.println("请输入车牌号"); Scanner sc = new Scanner(System.in); String carno = sc.next(); String t = carno.substring(0,2); checkAddressByCarCard(t); } private static void checkAddressByCarCard(String no){ String a[]={"浙A","浙B","浙C","浙D","浙E","浙F","浙G","浙H","浙J","浙K","浙L"}; String b[]={"杭州","宁波","温州","绍兴","湖州","嘉兴","金华","衢州","台州","丽水","舟山"}; int index = 0; for(int i = 0;i<11;i++){ if(no.equalsIgnoreCase(a[i])){ index=i; System.out.println("车辆所在地为："+b[i]); } } } } //不严谨，但是基本功能实现了

方法1：用hashtable键值对存储map("嘉兴","浙A");，以此类推方法2：存储到数据库、xml文件或者其他如果是练手就用1，项目就用2.

8，Java编写汽车类car

public class Car { private int num;//编号 private String name;//型号 private double price;//单价 /** * 无参构造 */ public Car(){ super(); } /** * 有参构造 * @param num * @param name * @param price */ public Car(int num, String name, double price) { super(); this.num = num; this.name = name; this.price = price; } public int getNum() { return num; } public void setNum(int num) { this.num = num; } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public String inforShow() { return "Car [num=" + num + ", name=" + name + ", price=" + price + "]"; } } public class PriCar extends Car{ private int PersonNum;//最大载客量 public PriCar(int personNum) { super(); PersonNum = personNum; } public PriCar() { super(); } public int getPersonNum() { return PersonNum; } public void setPersonNum(int personNum) { PersonNum = personNum; } @Override public String inforShow() { return "PriCar [PersonNum=" + PersonNum + "]"; } } public class VanCar extends Car { private double weight;//最大载重 public VanCar(double weight) { super(); this.weight = weight; } public VanCar() { super(); } @Override public String inforShow() { return "PriCar [num=" + super.getNum() + ", name=" + super.getName() + ", price=" + super.getPrice() +",weight=" + weight + "]"; } } 测试类不想写了应该可以自己写出来了吧

最简单的 import java.util.*; public class car cars = new arraylist(); cars.add(new car("aaa","ccc")); cars.add(new car("kkk","dss")); for(car car : cars)

9，1 编写一个Java应用程序设计一个汽车类Vehicle包含的成员属性

/* *编译运行均已通过 *直接复制黏贴即可 *文件名为：Test.java */ class Vehicle { private int wheels; private float weight; protected Vehicle(int wheels, float weight){ this.wheels = wheels; this.weight = weight; } public int getWheels() { return wheels; } public float getWeight() { return weight; } public void print(){ System.out.println("汽车："); System.out.println("共有"+this.getWheels()+"个轮子"); System.out.println("重量为"+this.getWeight()+"吨"); } } class Car extends Vehicle{ private int passenger_load; public Car(int wheels, float weight, int passenger_load) { super(wheels, weight); this.passenger_load = passenger_load; } public int getPassenger_load() { return passenger_load; } public void print(){ System.out.println("小车："); System.out.println("共有"+this.getWheels()+"个轮子"); System.out.println("重量为"+this.getWeight()+"吨"); System.out.println("载人数为"+this.getPassenger_load()+"人"); } } class Truck extends Vehicle{ private int passenger_load; private float payload; public Truck(int wheels, float weight, int passenger_load, float payload) { super(wheels, weight); this.passenger_load = passenger_load; this.payload = payload; } public int getPassenger_load() { return passenger_load; } public float getPayload() { return payload; } public void print(){ System.out.println("卡车："); System.out.println("共有"+this.getWheels()+"个轮子"); System.out.println("重量为"+this.getWeight()+"吨"); System.out.println("载人数为"+this.getPassenger_load()+"人"); System.out.println("载重量为"+this.getPayload()+"吨"); } } public class Test{ public static void main(String args[]){ Vehicle car = new Car(4, 3, 4); Vehicle truck = new Truck(6, 6, 2, 10); System.out.println("*****************************"); car.print(); System.out.println("*****************************"); truck.print(); } } /* *output: ***************************** 小车：共有4个轮子重量为3.0吨载人数为4人 ***************************** 卡车：共有6个轮子重量为6.0吨载人数为2人载重量为10.0吨 */
