WebThe problem is that FileInputStream only allows you to read byte by byte. I need to convert that byte into something like a BitSet so I can read each bit in the byte. The solution I came up with was: 1. Read the byte 2. Convert it to String using Integer.toBinaryString (byte) 3. Pad the String with zeros so there is 8 bits that can be read from it. WebEach byte array of the BitSet is set is the interval of each byte (8 bit) space. The length of a byte space increases if the set bit is set above the previous byte size. In this example, …

WebA QBitArray is an array that gives access to individual bits and provides operators ( AND, OR, XOR, and NOT) that work on entire arrays of bits. It uses implicit sharing (copy-on-write) to reduce memory usage and to avoid the needless copying of data. The following code constructs a QBitArray containing 200 bits initialized to false (0):
