Java Programming for Complete Beginners - Java 16 - Step 26 - Map Interface - Exercise - Count Occurrences of Characters

The video tutorial explains how to use Java's HashMap to count the occurrences of characters and words in a string. It begins with setting up a map for character counting, followed by an algorithm to iterate through the string and update the map with character counts. The tutorial then transitions to counting words using a similar approach, splitting the string into words and updating a map with word counts. The video concludes with suggestions for further improvements, such as handling punctuation.
