Thank you for watching once again guys! Sorry for the static in the audio, will be getting a new headset soon :P. I meant to note that Java is very case-sensitive and the name of the file (mainClass.java) should be the same as the text used in the code (mainClass). The uppercase "C" in both cases should be preserved. Same in any case where you are making a reference to the SAME object/variable (keep in mind for future tutorials). Thanks for reading this message, and if you have, post a comment that says "I'm the boss". ;)
