Intro

Caching is a technique that can significantly improve the performance and efficiency of Java applications by reducing the response time and load on the underlying data sources. In this article, we’ll discuss what caching is, how it works, and best practices for implementing caching in Java applications.

What is Caching?

Caching refers to the technique of storing frequently accessed data or results in memory so that they can be retrieved quickly the next time they are needed. Caching helps reduce the load on the data sources, such as databases or external APIs, by avoiding expensive calls to these sources. By caching frequently accessed data or results, Java applications can improve their performance and responsiveness.

Implementing Caching in Java

Caching can be implemented in Java using various techniques, including:

  1. Using the Java Collections Framework: Java provides various collection classes such as HashMap, TreeMap, and LinkedHashMap that can be used for caching. These collections can be used to store key-value pairs, where the key represents the data that needs to be cached, and the value represents the cached data.
  2. Using third-party caching libraries: There are many…
