创建对象的内存分析

代码示例

1. 创建一个Pet类

public class Pet {

    String name;
    int age;

    public void shot(){
        System.out.println("叫了一声");
    }
}

2. 实例化对象

public class Demo {

    public static void main(String[] args) {

        Pet dog = new Pet();
        dog.name = "旺财";
        dog.age = 1;
        dog.shot();

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

    }
}
