 1 | Introducing a new minor project in Java: a compressor and decompressor application. 
 2 | The primary objective of this project is to employ compression techniques to reduce the required number of bits for data representation. 
 3 | It strictly focuses on lossless conversion methods to ensure data integrity throughout the compression process. 
 4 | By implementing this project, users can benefit from various advantages of compression, including efficient storage utilization, accelerated file transfers, and decreased storage hardware and network bandwidth expenses. 
 5 | The emphasis on lossless compression techniques guarantees that no data is lost during the compression process, safeguarding the integrity of the compressed data.
