Technical requirements

To follow the instructions in this chapter, you’ll need the following:

• IntelliJ IDEA Community Edition (https://www.jetbrains.com/idea/download/)
• OpenJDK 19 or higher (https://jdk.java.net/19/)

The code files for this chapter are available at https://github.com/PacktPublishing/Kotlin-Design-Patterns-and-Best-Practices_Third-Edition/tree/main/Chapter01.

IMPORTANT NOTE:

For simple code snippets, there’s no requirement to write them in a file. You have the option to explore the language online, using platforms like https://play.kotlinlang.org/, or leverage a REPL and an interactive shell after installing Kotlin and executing the kotlinc command.
