SKB – Scala String Interpolation

SKB – Scala String Interpolation

Introduction

This article is part of the Scala knowledge bits Series.

Periodically, I will publish new exercises so you can slowly build up knowledge about Scala.

It is designed to be done in a very short amount of time and learn a little bit each day, just to create a routine.

This episode will teach you about Scala String Interpolation.

Hope you are going to enjoy it! It is designed for anyone to learn Scala from scratch and slowly learn, one Bit at a time.

After this Bit, I would love to hear your feedback in the comments down below.

What are we learning today?

Today we are going to learn about Scala String Interpolation !

Scala String Interpolation is how Strings can be constructed in Scala. It will be the way you can add Values inside a String.

Strings in programming languages are chains of character, for instance: "Hello World".

Time to try on the exercise on your own and scroll down for more information when you are done or if you are stuck.

Exercise

Here is an exercise to complete today.

If I did my job well, you should be able to guess by yourself the solution based on what you previously learned and based on the clues.

But if you get stuck, scroll down to get more information.

The goal of the exercise is to replace the ??? by a piece of code so that the exercise compiles and that’s how you win! Good luck!

You can fill the exercise right in here:

Or, if it does not load, go on to Scastie (YvHTOaC8SFCFpKzQLmd9ag).

More information about Scala String Interpolation

In this exercise you will learn (or have learned, if you have already solved the puzzle) about Scala String Interpolation.

You might have noticed the string is contained between quotes: "...".

An other thing to notice is the s preceding the first quote. It is necessary to transform $h into the content of the value h.

Feel free to go back to the exercise, modify the code to try out new things and get a better intuition for Scala String Interpolation.

Conclusion

I hope you have learned something new or had fun during this Scala Knowledge Bit.
