∟Managing Bit Strings in Byte Arrays

This chapter provides tutorial notes and tutorial examples on managing bit strings in byte arrays. Topics include setting a bit value into a byte array; getting a bit value back from a byte array; rotating all bits in a byte array.

setBit() - Storing a Bit into a Byte Array

getBit() - Retrieving a Bit from a Byte Array

rotateLeft() - Left Rotating All Bits in a Byte Array

bitStringTest.java - Testing Program

Takeaways:

Java has no built-in support for bit strings.
Bit strings can be stored in byte arrays.
getBit() and setBit() are easy to implement on byte arrays.
rotateLeft() is easy to apply on byte arrays also.
