java中byte a =(byte)为什么输出成-求大
这里没涉及原码补码反码吧,byte a =(byte)意思是反码把一个整形的转换为一个byte型的,由于byte类型的补码ccp 协议源码取舍范围只有-~,超出byte的源码取舍范围了,就从最小值-开始循环,反码蓝鸟棋牌源码比如(byte)比大1,补码源码修改视频接着就再取一位,源码也就是反码-,所以(byte)打印出来就是补码-了。(byte)打印出来就是源码-,这样循环轮回地取舍,反码byte a =(byte)输出成- 也一样道理。补码
至于原码补码反码这些,源码享物源码个人觉得,反码有些基本了解即可,补码比邻棋牌源码平时接触得不多,可以在用到的时候再深入学习,否则很容易忘记。
