01.	Program Details:

	(i)	Date: 26th September, 2019
	(ii)	Language: Java

02.	Problem Statement:

	(i)	Server solves following problems:
		a)	Show the value of pi,

	(i)	To compile the above programs,
		change the directory of the Terminal or Command Prompt to the folder containing these files.

	(ii)	Then, enter 'javac Server.java' and 'javac Client.java' to compile these files.
		You can only run these files after compiling them.

	(iii)	Finally, to run these files correctly,
		first, run 'Server.class' by entering 'java Server' then run 'Client.class' by entering 'java Client'.
