主要语言是用PHP做的哦。当然会有什么JAVA脚本，DOM，还有异步交换啥的，
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
class Car
{
// 车辆属性
private String brand; // 品牌
private double engineDisplacement;// 排气量
private double speed;// 当前速度
private boolean status;// 启动状态
private double maxSpeed;// 最大速度
public double getSpeed () {
return this.speed;
}
public Car(String brand, double engineDisplacement, double maxSpeed) {
this.brand = brand;
this.engineDisplacement = engineDisplacement;
this.maxSpeed = maxSpeed;
// 其他属性也要有初始值，不然执行出错。
this.speed = 0;
this.status = false;
}
/** 启动 */
public void start() {
this.status = true;
printNowStatus ();
}
/** 关闭（熄火） */
public void stop() {
// 只在速度为0时关闭（貌似楼上两位没仔细看题…）
if (this.speed == 0)
{
this.status = false;
}
printNowStatus ();
}
/** 加速 */
public void speedUp() {
// 只在启动时可以加速
if (this.status)
{
this.speed = this.speed + 20;
if (this.speed this.maxSpeed)
{
this.speed = this.maxSpeed;
}
}
printNowStatus ();
}
/** 减速 */
public void slowDown() {
// 只在启动时可以减速
if (this.status)
{
this.speed = this.speed - 10;
if (this.speed 0)
{
this.speed = 0;
}
}
printNowStatus ();
}
/** 状态打印，在每次启动，加减速，关闭时调用 */
private void printNowStatus () {
System.out.println("轿车【" + this.brand + "】现在的启动状态是：" + this.status + "速度是：" + this.speed +"。");
}
}
public class TestCar
{
public static void main(String[] args)
{

//启动
myCar.start();
// 循环加速到120
while (myCar.getSpeed() 120)
{
myCar.speedUp();
}
//循环减速
while (myCar.getSpeed() 0)
{
myCar.slowDown();
}
//关闭
myCar.stop();
}
}
/* 直接拿文本写的，我用的电脑没装jdk，楼主自己到Java开发环境下调试，应该没什么问题… */
