huffman-encoding

A java program to compress files using huffman encoding.

Implementation of variants of Huffman encoding, a lossless data compression algo-rithm that is used in encoding schemes such as JPEG and MP3 (MPEG-1).

Encode

Takes in a file name, compresses the file, and outputs the compressed file with a codemap header.

Usage:

java Zipper zipper [target] [destination]

• Target: The name of the file, folder to be compressed
• Destination: The name of the output file

Decode

Decoding reverse the encode operation. Given any valid output file from encode, decode
should reproduce the original file.

Usage:

java Zipper unzipper [target] [destination]

• Target: The name of the file, folder to be decompressed
• Destination: The name of the decompressed file (to be created)
