Scala & Spark-Master Big Data with Scala and Spark - Using Maps for Word Count

This video tutorial explains how to create a program that counts user-entered words using a map. It covers adding new words with an initial count, updating the count for existing words, and handling multiple entries. The tutorial includes a demonstration of the program's functionality and concludes with a preview of the next steps, where users can check the count of specific words.

What will the program output if the user enters the word 'apple' three times?

How does the program handle a situation where a user wants to check the count of a word?

What will the program inform the user if they enter a word that is not present in the map?
