Hi all,
Hope u all are fine =), I created a simple network layer with kryonet, this can work as a sample application for kryonet.

enjoy!
P.S: I m sending this time single object, I will update this for sending the multiple objects (array of objects) and some complex objects, which exploit KRYO Serialization capabilities.
