Create a console based, non-GUI Java program using an Integrated Development Environment (IDE) (or directly from the command line compiler) that displays "Hello world!".
Submit a copy of your program. The program must successfully compile and execute. You can use any IDE or the command line. Zip up your program (not the whole project - just the *.java file(s)) and submit it. I rebuild and re-run all submitted programs. Screenshot is not required.
