Write a program that implements message flow from top layer
Computer Science
Write a program that implements message flow from the top layer to the bottom layer of the 7-layer protocol model.
Your program should include a separate protocol function for each layer. Each protocol function has takes a message passed from the higher layer protocol. It attaches its own header in front of the message (an arbitrary layer identifier of up to 64 characters), prints the new message on the standard output, and invokes the protocol function of the next lower-layer protocol.
Program input is an arbitrary application message.
The program must be written in Java.
