File Compression Tool 🔥

A Java-based file compression tool that implements three compression algorithms:
✔ Huffman Encoding (Lossless Compression)
✔ LZW (Lempel–Ziv–Welch) Compression
✔ Run-Length Encoding (RLE)
✔ Graphical User Interface (GUI)
✔ Multi-threading for large files
✔ File selection, compression, and decompression

This tool comes with a GUI built using Swing, allowing users to compress and decompress files easily.

📌 Features

✅ Huffman Compression – Best for text-heavy files 🐝
✅ LZW Compression – Efficient dictionary-based encoding 🐂
✅ RLE Compression – Simple and fast for repetitive data 🔀
✅ Graphical User Interface (GUI) – Easy-to-use file selection & operations 🎨
✅ Multi-threading Support – Ensures smooth performance ⚡
