两个对象使用同一个方法的内存图与两个引用指向同一个对象的内存图

本文主要是介绍两个对象使用同一个方法的内存图与两个引用指向同一个对象的内存图，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

两个对象使用同一个方法的内存图

public class PhoneDemo02 {
    public static void main(String[] args) {
        phone phone = new phone();
        System.out.println(phone.brand);
        System.out.println(phone.color);
        System.out.println(phone.price);
        System.out.println("******************");
        phone.brand = "苹果";
        phone.color = "土豪金";
        phone.price =1.3;
        System.out.println("******************");
        System.out.println(phone.brand);
        System.out.println(phone.color);
        System.out.println(phone.price);
        System.out.println("******************");
        phone.call("秦始皇");
        phone.sendMessage();
        System.out.println("******************");
        phone phtow = new phone();
        System.out.println(phtow.brand);
        System.out.println(phtow.color);
        System.out.println(phtow.price);
        System.out.println("******************");
        phtow.brand = "oppo";
        phtow.color = "金色";
        phtow.price =9.9;
        System.out.println("******************");
        System.out.println(phtow.brand);
        System.out.println(phtow.color);
        System.out.println(phtow.price);
        System.out.println("******************");
        phtow.call("汉高祖");
        phtow.sendMessage();

    }
}

public class PhoneDemo03 {
    public static void main(String[] args) {
        phone phone = new phone();
        System.out.println(phone.brand);
        System.out.println(phone.color);
        System.out.println(phone.price);
        System.out.println("******************");
        phone.brand = "苹果";
        phone.color = "土豪金";
        phone.price =1.3;

        System.out.println(phone.brand);
        System.out.println(phone.color);
        System.out.println(phone.price);
        System.out.println("******************");
        phone.call("秦始皇");
        phone.sendMessage();
        System.out.println("******************");
        phone phtow =phone;
        System.out.println(phtow.brand);
        System.out.println(phtow.color);
        System.out.println(phtow.price);
        System.out.println("******************");
        phtow.brand = "oppo";
        phtow.color = "金色";
        phtow.price =9.9;
        System.out.println("******************");
        System.out.println(phtow.brand);
        System.out.println(phtow.color);
        System.out.println(phtow.price);
        System.out.println("******************");
        phtow.call("汉高祖");
        phtow.sendMessage();

    }
}
