I honestly am unsure about that, however I can assist with the downloading SimplePaint and keeping it from becoming a .txt file! So when you have it pulled up and click on save as, change the location to be directly into the Lab1 folder, the same place as App.java! If it still becomes a .txt, open the file in Intellij and right click on the SimplePaint tab at the top and it should give you an option to rename it. Just remove the .txt portion of the name and it should work!
