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!

请问如何用Java编写一个汽车类Car

public class Car {

private String color;//颜色

private int door;//车门数量

private float speed;//车速

public Car(){

this.color = "红色";

this.door = 3;

this.speed = 110;

}

public Car(String color, int door, float speed) {

this.color = color;

this.door = door;

this.speed = speed;

}

public void start(){

//汽车启动。输出汽车已启动,并输出汽车的各个属性

System.out.println("汽车已启动,汽车颜色为"+color+",车门数为"+door+",车速为"+speed);

}

public void speedUp(float speed){

//加速

System.out.println("汽车加速到"+speed+"km/h");

}

public void shutDown(float speed){

//减速

System.out.println("汽车减速到"+speed+"km/h");

}

public void brake(){

//刹车

System.out.println("已刹车");

}

}

public class Test {

public static void main(String[] args){

Car car = new Car();

car.start();

car.speedUp(100);

car.shutDown(60);

car.brake();

Car car1 = new Car("白色",4,20.2F);

car1.start();

car1.speedUp(100);

car1.shutDown(60);

car1.brake();

}

}

运行结果

JAVA代码编写!求帮忙!求教

第一题:

Car.java

public class Car {

public String num;

public float price;

public Car(String num,float price){

this.num = num;

this.price=price;

System.out.println("车牌号为:"+num+",价格为:"+price);

}

}

测试类:

public class CarTest {

public static void main(String[] args) {

Car car = new Car("京P34E68", 100000.23f);

}

}

输出为:车牌号为:京P34E68,价格为:100000.23

第二题:

Student.java

public class Student {

private String num;

private String name;

private int age;

private String sex;

public String getNum() {

return num;

}

public void setNum(String num) {

this.num = num;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

public String tell() {

return "Student [num=" + num + ", name=" + name + ", age=" + age+ ", sex=" + sex + "]";

}

public static void main(String[] args) {

Student student = new Student();

student.setAge(18);

student.setNum("001");

student.setName("COLD");

student.setSex("男");

System.out.println(student.tell());

}

}

输出:Student [num=001, name=COLD, age=18, sex=男]

希望能帮到你,望采纳

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
