 填零 Explanation:同意以上二位的翻译，补充一些解释。 >> 和 << 是计算机语言中常用的位运算符。 是在二进制数上进行操作的运算符号。 多数计算语言，例如 C 和 C++ 等，只有 << 和 >> 两个位运算符，分别称为“左移”运算符和“右移”运算符。JAVA等新的计算语言，由于所有的整形数据类型都是带符号的，所以增添了一个新的位运算符 >>> ，通常译为“无符号右移”。<< 的作用相当于原数乘以2 ，>> 的作用相当于原数除以2 。 在 JAVA 中，整形数的最左面一位是代表符号的，即规定该数是正数还是负数。 在 JAVA中，<< 和 >> 的作用是一个二进制数的每一位都向左或向右移动若干位，同时保留最左位上的符号，就是说，原来是正数的，移动后还是正数。 >>> 的作用将原数的所有位都向右移动若干位，同时在最右边添加若干个零。 与它相对照，>> 在右移时，左面或填０或填１，视该数的正负而定。 这句话似可译为： 以无符号右移运算符>>> 进行“右移填零”。--------------------------------------------------Note added at 2002-04-01 09:23:53 (GMT)--------------------------------------------------更正： >>> 的作用将原数的所有位都向右移动若干位，同时在最*右*边添加若干个零。 应为： >>> 的作用将原数的所有位都向右移动若干位，同时在最*左*边添加若干个零。
