对象内存分析

1,新建Application类，作为程序的入口

package oop;

import oop.demo03.Pet;

public class Application {
    public static void main(String[] args) {
        Pet pig = new Pet();
        pig.name="小朱佩奇";
        pig.age=3;
        pig.shout();

        System.out.println("name:"+pig.name);
        System.out.println("age:"+pig.age);
    }
}

2,新建Pet类

package oop.demo03;

/*

 */
//宠物类
public class Pet {
    public String name;
    public int age;

    public void shout() {
        System.out.println("宠物叫了！！");
    }
}

4,运行结果
