Int b 298 a byte b
Netteta=（byte）b；楼上的很对 这个是类型转换。 补充下、如果把b转换为byte类型、首先b必须是byte类型的值举个例子 int a;string b;如果b=值是“aaa”那么a=int (b)这样会出错的。 只有b的值是int类型才会转换成功。 1 评论 分享 举报 匿名用户 2013-09-23 (类型）这是一个强制转换的用法。 比如float f = 3.2f; int a = (int)f; 就可以把f强制转换成int赋值给a。 … Nettet5. nov. 2024 · The byte data type has min value -128(=-2^7) and max value 127(=2^7-1).

Nettet当一个int和 0xff进行与运算时， 即表示提取这个int的最低八位 。 例如： int a = 10000;// a的二进制为 10011100010000 int b = a & 0xff;// a和0xff 与运算后，b的二进制为 10000，即十进制的16 System.out.println ("b的十进制="+b);// 输出16 n >>> 8（位运算）： >>8表示右移8位，如果该数为正，则高位补0，若为负数，则高位补1； 例如： Nettet14. apr. 2024 · a = -128 b = 127 分析：首先byte的范围为-128~127。 字节长度为8位，最左边的是符号位，而127的二进制为：0111 1111，所以执行++a时，0111 111变为1000 0000，而128的二进制为：1000 0000，即为127+1=-128；而add (b)其实为add (127)，而b=b++其实为b=127,b++;则b=127。 愿你悄悄的努力，遇见更好的自己~ 分类: 基础 好 …
