My first game in Java!

I found an amazing tutorial for writing a brick breaking style game in Java. I walked through the video, typing all of the code, and was able to fully reproduce the game! In some respect, I suppose it's similar to tracing a drawing, but either way, I am so happy with the results. My first hello world app took me about 90 minutes to finish. I finished the game in about two hours.

// Main.java

/*
