How to Use Guava BiMap for Inverse Map Lookup

A BiMap is useful in scenarios where you need to look up data in both directions.

For example, if you have a mapping between employee IDs and names, and you want to quickly retrieve an employee’s ID based on their name or vice versa, a BiMap can provide this functionality.

Guava provides an implementation of the BiMap interface called HashBiMap. Let’s see you can use it.

Use Guava Multiset to Count the Occurences of Elements in a List

The Multiset class in Google’s Guava library provides a powerful data structure that extends the capabilities of a traditional Set by allowing multiple occurrences of the same element. This makes Multiset particularly useful for counting elements and solving problems where element frequency matters.
