Scala Exercises, Practice, Solution

The Scala Programming Language

Scala is a general-purpose programming language providing support for both object-oriented programming and functional programming. The language has a strong static type system. Designed to be concise, many of Scala's design decisions are aimed to address criticisms of Java

The best way we learn anything is by practice and exercise questions. Here you have the opportunity to practice the Scala programming language concepts by solving the exercises starting from basic to more complex exercises. A sample solution is provided for each exercise. It is recommended to do these exercises by yourself first before checking the solution.

Hope, these exercises help you to improve your Scala programming coding skills. Currently, following sections are available, we are working hard to add more exercises .... Happy Coding!
