Extasys - Asynchronous TCP/UDP socket library

Extasys is a high performance, asynchronous TCP/UDP socket library for Java (JDK 8 and newer).
Its multi-threaded and lightweight nature makes it ideal for super fast data transfer even on systems with ARM architecture like Android smartphones and single-board computers (Raspberry Pi, Orange Pi etc.).

If you are using sockets then Extasys is the proper tool for your work. It's been designed to take the hard job done and let you think only about the message exchange (the process).
