App supports HD resolution, so each frame is split into smaller chunks due to the maximum UDP frame size (65kb). I decided to create simple error correction system, because UDP protocol can loose the packets which caused visible artifacts in result video stream.
TL;DR: If the image fragments were not transmitted in the correct order, frame is not displayed in the user interface. Solves the problem of displaying artifacts in the image.

To install the program on your computer, use the command below (or use the build-in GIT system in your IDE environment):
$ git clone https://github.com/Milosz08/screen-sharing-system
- Build and install shared library via:
$ mvn -N clean package install- Create executable JAR file for modules:
$ mvn -pl "<module>" clean assembly:assemblywhere <module> is client or host.
- Optionally, build all modules via (for UNIX system):
$ ./packageor for Windows system:
.\package.batAll executable JAR files will be available in .bin directory.
