这部分数据的长度在32位和64位的虚拟机(暂不考虑开启压缩指针的场景)中分别为32个和64个bits。 对象需要存储的运行时数据很多,其实已经超出了32、64位Bitmap结构所能记录的限度,但是对象头信息是与对象自身定义的数据无关的额外存储成本,考虑到虚拟机的空间效率,Mark Word被设计成一个非固定的数据结构以便在极小...

int 占用四个字节,也就是 32 位,1 int = 32 bits,默认值是 0 ; long 占用八个字节,也就是 64 位,1 long = 64 bits,默认值是 0L; 所以整数型的占用字节大小空间为 long > int > short > byte 浮点型 浮点型有两种数据类型:float 和 double float 是单精度浮点型,占用 4 位,1 float = 32 bi...
