Java Java Objects (Retired) Meet Objects Welcome Back

Just Asking.

So i always take notes in a notebook while watching these videos and am kinda confused as to what i should put down for notes of this video. And Will we always be using repl?

What 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!

The 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

Thanks guys but is there anything very important that i should put down in my notes from this video
