My attempt at building a functional cache

Problem Statement

We have to do low level design for a Cache system. Cache that we will design will have to support following operations:

• Put: This will allow user to put a value against a key in the cache.
• Get: This will allow user to get the previously saved value using key.
• Eviction: Cache should also support removal of some key in case cache is full, and we try to add new key value.

Expectations

• Code should be functionally correct.
• Code should be modular and readable. Clean and professional level code.
• Code should be extensible and scalable. Means it should be able to accommodate new requirements with minimal changes.
• Code should have good OOPs design.
