A File Compression software that helps zip/Unzip files using these 2 algorithms:

1. Huffmans Code
2. Lempel-Ziv-Wells algorithm

The Huffmans algo creates a 1-1 mapping for each byte of the input file and replaces each byte with the mapped bit sequence. For this you need to store a dictionary that describes each 1-1 mapping of input byte and binary sequence.(which needs extraspace)

Unlike Huffmans code LZW dont need an extra dictionary to be saved. Also LZW does not create a mapping to byte to bin sequence. It creates mapping of multiple byte to binary sequence.

• Java 21 or higher
• Maven (for building)

brew install maven

mvn -version

I have included the already build jar file. You can run it simply if you dont want to build

java -jar file-compression-2.0-SNAPSHOT-jar-with-dependencies.jar

mvn clean package
mvn test
mvn exec:java

After building with Maven, you can run the JAR:

java -jar target/file-compression-2.0-SNAPSHOT-jar-with-dependencies.jar

Outlook

I tested this project in: MacOS Tahoe (version 26.0.1)
