Keurig makes Java (programs from source)
Download .zip here. There's a .app inside, just put it in your Applications folder.
macOS only.
Must have Java and JDK installed. Make sure both are up to date.
Keurig compiles and runs Java programs from source. Convenient for ITI1121 course at uOttawa, where IDEs are discouraged. Makes the compilation/running step a bit less cumbersome.
