1. 用java定义一个汽车类Automobile，



classAutomobile
{
	privateString发动机型号;

	privateint座位数;

	publicStringget发动机型号()
	{
		return发动机型号;
	}

	publicvoidset发动机型号(String发动机型号)
	{
		this.发动机型号=发动机型号;
	}

	publicintget座位数()
	{
		return座位数;
	}

	publicvoidset座位数(int座位数)
	{
		this.座位数=座位数;
	}

	@Override
	publicStringtoString()
	{
		returnString.format("[发动机型号=%s,座位数=%s]",发动机型号,座位数);
	}
}

interface收费
{
	publicvoid收费方法();
}

interface调速
{
	publicvoid调速方法();
}

class公共汽车extendsAutomobileimplements收费,调速
{
	@Override
	publicvoid调速方法()
	{
		System.out.println("速度非常慢");
	}

	@Override
	publicvoid收费方法()
	{
		System.out.println("天价呢");
	}
}

class出租车extendsAutomobileimplements收费,调速
{
	@Override
	publicvoid调速方法()
	{
		System.out.println("速度是20公里每小时");
	}

	@Override
	publicvoid收费方法()
	{
		System.out.println("出租车的收费是便宜的");
	}
}

publicclassMain
{
	publicstaticvoidmain(String[]args)
	{
		出租车czc=new出租车();
		czc.set发动机型号("abc");
		czc.set座位数(4);
		System.out.println(czc);
		czc.调速方法();
		czc.收费方法();
		
		公共汽车ggqc=new公共汽车();
		ggqc.set发动机型号("ddf");
		ggqc.set座位数(30);
		System.out.println(ggqc);
		ggqc.调速方法();
		ggqc.收费方法();
	}
}

2. 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

3. Java编写汽车类car

publicclassCar{
	
	privateintnum;//编号
	privateStringname;//型号
	privatedoubleprice;//单价
	
	/**
	*无参构造
	*/
	publicCar(){
		super();
	}
	
	/**
	*有参构造
	*@paramnum
	*@paramname
	*@paramprice
	*/
	publicCar(intnum,Stringname,doubleprice){
		super();
		this.num=num;
		this.name=name;
		this.price=price;
	}

	publicintgetNum(){
		returnnum;
	}

	publicvoidsetNum(intnum){
		this.num=num;
	}

	publicStringgetName(){
		returnname;
	}

	publicvoidsetName(Stringname){
		this.name=name;
	}

	publicdoublegetPrice(){
		returnprice;
	}

	publicvoidsetPrice(doubleprice){
		this.price=price;
	}

	publicStringinforShow(){
		return"Car[num="+num+",name="+name+",price="+price+"]";
	}
	
	

}publicclassPriCarextendsCar{

	privateintPersonNum;//最大载客量

	publicPriCar(intpersonNum){
		super();
		PersonNum=personNum;
	}

	publicPriCar(){
		super();
	}

	publicintgetPersonNum(){
		returnPersonNum;
	}

	publicvoidsetPersonNum(intpersonNum){
		PersonNum=personNum;
	}

	@Override
	publicStringinforShow(){
		return"PriCar[PersonNum="+PersonNum+"]";
	}
	
	
}publicclassVanCarextendsCar{

	privatedoubleweight;//最大载重

	publicVanCar(doubleweight){
		super();
		this.weight=weight;
	}

	publicVanCar(){
		super();
	}
	
	@Override
	publicStringinforShow(){
		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

4. 大神们怎么用java画汽车

1.最简单的方法：
publicstaticStringreverse1(Stringstr)
{
returnnewStringBuffer(str).reverse().toString();
}
2.最常用的方法：
publicstaticStringreverse3(Strings)
{
char[]array=s.toCharArray();
Stringreverse="";//注意这是空串，不是null
for(inti=array.length-1;i>=0;i--)
reverse+=array[i];
returnreverse;
}
3.常用方法的变形：
publicstaticStringreverse2(Strings)
{
intlength=s.length();
Stringreverse="";//注意这是空串，不是null
for(inti=0;i<length;i++)
reverse=s.charAt(i)+reverse;//在字符串前面连接，而非常见的后面
returnreverse;
}
4.C语言中常用的方法：
publicstaticStringreverse5(Stringorig)
{
char[]s=orig.toCharArray();
intn=s.length-1;
inthalfLength=n/2;
for(inti=0;i<=halfLength;i++){
chartemp=s[i];
s[i]=s[n-i];
s[n-i]=temp;
}
returnnewString(s);//知道char数组和String相互转化
}

5. java定义一个汽车类car

你好，很高兴回答你的问题。
题目要求的代码如下:
public class Car{
private String carNumber;
private int speed;
}

6. JAVA 建立一个汽车AutoMobile类......

publicclassAutoMobile{
protectedintnumbersOfWheels;
;
protectedintautoMobileWeight;
protectedintspeed;

publicAutoMobile(){
this(4,"黑色",100);
}

publicAutoMobile(intnumbersOfWheels,StringautoMobileColor,intautoMobileWeight){
this.numbersOfWheels=numbersOfWheels;
this.autoMobileColor=autoMobileColor;
this.autoMobileWeight=autoMobileWeight;
this.speed=0;
}
publicvoidspeedUp(){
speed++;
System.out.println("这是AutoMobile的加速方法，当前速度："+speed);
}
publicvoidspeedDown(){
speed--;
System.out.println("这是AutoMobile的减速方法，当前速度："+speed);
}
publicvoidstop(){
speed=0;
System.out.println("这是AutoMobile的停车方法，当前速度："+speed);
}
publicintgetNumbersOfWheels(){
returnnumbersOfWheels;
}
publicvoidsetNumbersOfWheels(intnumbersOfWheels){
this.numbersOfWheels=numbersOfWheels;
}
(){
returnautoMobileColor;
}
publicvoidsetAutoMobileColor(StringautoMobileColor){
this.autoMobileColor=autoMobileColor;
}
publicintgetAutoMobileWeight(){
returnautoMobileWeight;
}
publicvoidsetAutoMobileWeight(intautoMobileWeight){
this.autoMobileWeight=autoMobileWeight;
}
publicintgetSpeed(){
returnspeed;
}
publicvoidsetSpeed(intspeed){
this.speed=speed;
}
}
{
protectedStringairConditioner;
protectedStringcd;
publicCar(){
super();
this.airConditioner="空调A";
this.cd="sony";
}
publicvoidspeedUp(){
speed+=2;
System.out.println("这是Car的加速方法，当前速度："+speed);
}
publicvoidspeedDown(){
speed-=2;
System.out.println("这是Car的减速方法，当前速度："+speed);
}
publicStringgetAirConditioner(){
returnairConditioner;
}
publicvoidsetAirConditioner(StringairConditioner){
this.airConditioner=airConditioner;
}
publicStringgetCd(){
returncd;
}
publicvoidsetCd(Stringcd){
this.cd=cd;
}
}
publicclassTest{

publicstaticvoidmain(String[]args){

Carcar=newCar();

car.speedUp();

car.speedUp();

car.speedDown();

car.stop();

}

}

7. JAVA汽车

import java.awt.Color;

class Car {
Color color; //颜色
double price; //价格
String licensePlate; //车牌

public void start() {}
public void stop() {}
}

class BMW extends Car {
Color color = Color.BLACK;
}

不满意的话，随便回改。答

8. 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;
}

}
