类的定义与对象的创建使用

定义类：

///定义手机类/属性：创建品牌、颜色、价格//行为：打电话给xxx        群发短信publiclicch class phone {    String brand;    String color;    int price;    public void call(String name){        System.out.println("给"+ name +“打电话”;    }    public void sendMessage(){        System.out.println(“输出群发短信”;    }}///编写手机测试类，创建两个对象并赋值public class phoneTest {    public static void main(String[] args) {        phone ph1=new phone();        ph1.brand="小米";        ph1.color="白色";        ph1.price=4999;        System.out.println(ph1.brand);        System.out.println(ph1.color);        System.out.println(ph1.price);        ph1.call(张三);        ph1.sendMessage();        System.out.println("------------");        phone ph2=new phone();        ph2.brand="华为";        ph2.color="黑色";        ph2.price=6999;        System.out.println(ph2.brand);        System.out.println(ph2.color);        System.out.println(ph2.price);        ph2.call(李四);        ph2.sendMessage();    }}
