LZ VERSION 1.0


PROGRAM DESCRIPTION:
	This application demonstrates the way LZ77, LZ78 
	and LZW data compression algorithms work. It uses a string as 
	input and displays the process of the encoding and decoding.

LANGUAGE USED:
	The language used is JAVA (JDK 1.2)

REQUIREMENTS TO RUN THE PROGRAM:
	Computer:	Any type of computer which can run the java 
                        virtual machine
	Software:	JDK1.2 
		    	MS-DOS to type the command lines


HOW TO RUN (START) THE PROGRAM:
			* Go to the DOS prompt 
			* Go to the directory where the class files are 
			  stored. From that directory run the program using jdk1.2.
	
        	Example:  
			Go to the directory
			c:\>cd LZ
			c:\LZ>java LZ
			
			The application will appear on the screen.
