Scala & Spark-Master Big Data with Scala and Spark - Scala Setup (Local Machine)

This video tutorial guides viewers through the process of installing Java and Scala on a local machine. It covers downloading the necessary files, setting up environment variables, and running a simple Hello World program to ensure everything is configured correctly. The tutorial also hints at future videos that will explore using online IDEs for Scala development.
