Courses Plus Student 16,352 PointsThe Welcome Back video is all about the Java REPL, and the course uses it all the time. I find it incredibly useful to quickly test short functions or call methods on an array, etc.
The teacher's notes provide a link to a Java REPL, but I tend to use repl.it, because it supports a wide variety of languages.
Hope this helps,
Cheers

30 PointsWhat video are you particularly asking about?
And Java REPL is a simple Read-Eval-Print-Loop. It is just a quick way to type in code in the console and see what it evaluates to.
You'll use repl in a pretty good bit of the Java track from what I remember, but it doesn't change any outcome of the code that you have written. They just use it for instructional purposes in the video.
Let me know which video you are referring to.
Thanks!
