What's the use of
What's the use of "& 0xff" in programming? - Oscar Liang

The & operator performs a bitwise AND operation. a & b will give you an integer with a ,bit, pattern that has a 0 in all positions where b has a 0, while in all positions where b has a 1, the corresponding ,bit, value froma is used (this also goes the other way around). For example, the bitwise AND of 10110111 and00001101 is 00000101.

This is a general question, but let's talk ,Java, for the example. Primitive types byte and short are signed. If I'm not too wrong, the sign ,bit, is the leftmost. Here's some code (in ,Java,) with simple ,masking,: 1 byte b = -100; 2 short s = -100; 3 System.out.println(b); 4 System.out.println(s);

Bits, that are set to 0 in the flag will be unchanged in the ,mask,. public void SetToggle(Flag flg) { ,Mask, ^= ( ulong )flg; } Since a flag has exactly one digit with a value of 1, and the rest of the digits 0, this will leave the ,mask, unchanged, except for the position where there is a value 1:

Bit Shifting (left shift right shift) | Interview Cake

When shifting right with an arithmetic right shift, the least-significant ,bit, is lost and the most-significant ,bit, is copied. Languages handle arithmetic and logical right shifting in different ways. ,Java, provides two right shift operators: >> does an arithmetic right shift and >>> does a logical right shift.
