The program creates a swing graphical interface with the following
description:
1.
The
user can specify two hosts <tcphost> and <udphost> to run the etcp and eudp processes.
2.
A
button to start the program.
3.
A
button to end the program with cancellation option.
4.
A
text line to enter a text to be sent to the etcp and eudp processes.
5.
Two
text areas to display the echoed lines sent by the eudp
and the etcp processes.
The program creates the etcp process at <tcphost> and the eudp process at <udphost>. It then sends each line typed by the user to
both of these two processes. The etcp and the eudp processes echoes back and then saves the received lines under files etcpFile and eudpFile.
Make sure that the program can run from any arbitrary directory
and all the processes are terminated when the program ends. Do not use any
fixed ports in your program, use only any available ports.
