A Scala worksheet is a tool that can be used in the Scala IDE to provide instant feedback on your Scala code. The worksheet automatically invokes the Scala interpreter every time the file is saved and provides the results immediately on the right side of the worksheet
- A really nice feature of Scala…is that it provides several ways…to code and test our programs.…One option is using and IDE where we can create…what they call a Scala worksheet.…A worksheet in the Scala IDE automatically invokes…the Scala interpreter and is going…to provide us with realtime feedback.…Let's get started.…We're going to start by creating a new project.…I'll go to File > New > Scala Project…and I'm going to call my project WorksheetExample.…
Notice I don't put any spaces in my name…and I'm going to click Finish.…Now if I expand worksheet example you'll see an src package.…I'm going to right-click on that, go to New,…and all the way down towards the bottom…you should have Scala worksheet.…I'm going to call this worksheet1 and click Finish.…Let me minimize the package explorer,…as well as the Outline view,…so we can see the entire worksheet.…Because what's nice about a Scala worksheet is that…as we type in statements inside of our worksheet…on the right-hand side it prints out the output.…
Every time we save it, it will automatically compile,…
Join Peggy Fisher as she helps get you started with Scala, so you can leverage the unique capabilities it offers. First, learn the basics of type inference, variables, loops, functions, and operators. Then, find out how to read files using a console, perform pattern matching, handle exceptions, and more. Finally, learn how to use classes, fields, methods, and objects.
