创建对象内存分析

Pet.java

package com.oop.demo03;

public class Pet {
    public String name;
    public int age;

    //无参构造
    public void shout(){
        System.out.println("叫了一声");
    }
}

Application.java

package com.oop;

import com.oop.demo03.Pet;

public class Application {
    public static void main(String[] args) {
        Pet dog = new Pet();
        dog.name = "旺财";
        dog.age = 3;
        dog.shout();

        System.out.println(dog.name);
        System.out.println(dog.age);

        Pet cat = new Pet();


    }   
}

结果是：

叫了一声
旺财
