Instructions for running the demo
Put all demo files in the same directory. Open a command window or terminal
and go to the directory where you stored the files. For example, if the
files were stored in directory C:\CS1027\demo3, in the command window type
java -jar DemoAssignment3.jar
You can also double-click on the icon of file DemoAssignment3.jar, but then
you will now be able to run the program step by step.
