The Java programming language also provides operators that perform bitwise and bit shift operations on integral types. The operators discussed in this section are less commonly used. Therefore, their coverage is brief; the intent is to simply make you aware that these operators exist. The unary bitwise complement operator "~" inverts a bit pattern; it can be applied to any of the integral types, ...
If the directory permissions have the Sticky bit set, a file can be deleted only by the owner of the file, the owner of the directory, 看了这一段，有些不明白，普通的文件夹不需要使用Sticky bit，其他用户也不能删除，只有OWNER才能删除
