int和integer 占用内存一样,都是4个字节。int与Integer的不同点:1、int类基本数据类型,而Integer为引用数据类型。2、int占4个字节,用于存储int类型的值, Integer占4个字节,用于存储Integer对象的内存地址。3、作为成员变量时,int的默认值为0,Integer的默认为null。4、Integer使用null表示没有创建...

Integer在内存中有一个指向方法区里边类信息的指针,这个指针占用4bytes,另外Integer中实例变量只有一个int类型的字段,所以为32位,4bytes。在不考虑lock、waitset、gc相关信息占用的时候,有4bytes的指向对象池的指针,一共是3*4=12bytes。integer,整数/整型数,与小数/浮点数相对,是编程语言的基本...
