Is it possible to read/write bits from a file using JAVA?

Question

To read/write binary files, I am using DataInputStream/DataOutputStream, they have this method writeByte()/readByte(), but what I want to do is read/write bits? Is it possib

Answer 1

Bits are packaged in bytes and apart from VHDL/Verilog I have seen no language that allows you to append individual bits to a stream. Cache up your bits and pack them into a byte for a write using a buffer and bitmasking. Do the reverse for read, i.e. keep a pointer in your buffer and increment it as you return individually masked bits.
