What are Environment Variables?
Environment variables are a special type of variable that is stored outside the program and can affect how the program runs depending on the computer. For example, the HOME environment variable represents the home directory.
How to Read Environment Variables in Scala?
Scala stands for scalable language. It is an object-oriented language that provides support for functional programming approach as well. Everything in scala is an object e.g. – values like 1,2 can invoke functions like toString(). Scala is a statically typed language although unlike other statically typed languages like C, C++, or Java, it doesn’t require type information while writing the code. The type verification is done at the compile time. Static typing allows to building of safe systems by default. Smart built-in checks and actionable error messages, combined with thread-safe data structures and collections, prevent many tricky bugs before the program first runs. In this article, we will see how we can read environment variables in Scala.
