Add “Anagram Grouping Program” in Java

[Rik-web-fullstack]

Create a Java program that groups a list of words that are anagrams of each other.

Example:
Input → ["eat", "tea", "tan", "ate", "nat", "bat"]
Output → [["eat", "tea", "ate"], ["tan", "nat"], ["bat"]]

Task:

• Implement the solution in Java (algorithms/AnagramGrouping.java).
• Use a HashMap where the key is the sorted version of each word, and the value is a list of all words matching that key.
• Return the grouped anagrams as a list of lists.
• Add clear comments explaining each step.
• Include one sample test case in the main() function for demonstration.
