关键词：对象-----在java中任何东西都被看做是对象；在程序中是指一组变量和相关方法的集合；其中变量表示对象的属性，方法表明对象所具有的行为。

比如汽车类所具有的一部分属性和行为：

package com.lovo;/** * 汽车类 * @author 李睿 * */public class Car {private String brand;private double price;private String material;private double speed;public Car(String brand, double price, String material, double speed) {super();this.brand = brand;this.price = price;this.material = material;this.speed = speed;}public void race(String compitition){System.out.println(brand + "正在进行" + compitition);}public void translate(String cargo){System.out.println(brand + "正在运送" + cargo);}public void showAbout(){System.out.println(brand + "售价为：" + price + "万元");System.out.println(brand + "主要由：" + material + "构成");System.out.println(brand + "时速为：" + speed + "km/h");}}

package com.lovo;public class Text02 {public static void main(String[] args) {Car c1 = new Car("Ferrari F12", 575, "复合材料", 380);Car c2 = new Car("Audio S5", 75, "合金材料", 285);c1.race("芒勒赛");c1.showAbout();c2.translate("冰冻大虾");c2.showAbout();}}
