[Solved] How to Implement Fibonacci Series with Memoization in Java 8? ConcurrentHashMap Caching Example

Hello guys, if you are wondering how to solve the Fibonacci series problem with memorization in Java then you have come to the right place. In the past, I have shared recursive and iterative Fibonacci series solution and in this article, I am going to show you how you can improve your solution using a technique called memorization which uses a cache to store the intermediate results. This is a very useful technique to solve Dynamic Programming problems like the Knapsack problem. The good thing about Java is that it provides rich libraries which have classes like ConcurrentHashMap which can be used as a cache to store these intermediary results instead of re-computing them. This can drastically reduce the time to calculate the Nth Fibonacci number.
