The main file used to run my program is EightPuzzle.java This is the file that you will need to compile and run in order to use the program.
The Node.java file is used to model a Node object and is utilized as a helper class in the main class, as mentioned above.
Compile all the java files in the directory using: javac *.java Then run the main file using: java EightPuzzle
Run the main file, EightPuzzle.java and you will be greeted with a command line interface. You will interact with the menu options.
You can follow the menu from this point on.
Thank you, Abraham Yepremian
