How do shift operators work in Java? [duplicate]
...the right. For example, the following program converts a byte value to its hexadecimal string representation. Notice that the shifted value is masked by ANDing it with 0x0f to discard any sign-extended bits so that the value can be used as an index into the array of hexadecimal characters.

What is the purpose of base 64 encoding and why it used in HTTP Basic Authentication?
...s stream is too exaggerated. It is better to compare it to storing data in hex format. Because hex would only make x2 more bytes than original stream, and 1s,0s - makes x8 times more bytes. (And Base64 makes x1.3 more data than original byte array). So sometimes it is acceptable to encode binary str...

...tc. where each byte is represented by 3 bytes. The data bloats three-fold.
Hexadecimal: store the bytes as hex pairs: AC 47 0D 1A etc. where each byte is represented by 2 bytes. The data bloats two-fold.
Base-64 maps 3 bytes (8 x 3 = 24 bits) in 4 characters that span 6-bits (6 x 4 = 24 bits). The...
