It's also the best way to write clean code; a code that can stand the test of time, a code that is flexible enough to accommodate future changes and a code that you don't afraid of while changing. Despite several efforts of promoting unit testing by programming community and emphasizing unit testing by many notable programmers, it's still one of the lacking practice.

The OOP or Object Oriented Programming is one of the most popular programming paradigms which helps you to organize code in the real-world system. It's a tool that allows you to write sophisticated software by thinking in terms of objects and relationships. Unlike its predecessor procedural Programming paradigm, which is implemented most notably by C, which solves the problem and complete task by writing code for computers, the OOP style of programming allows you to think in terms of real-world objects which have both state and behavior. You can view anything as objects and then find their state and behaviors, this will help you to simulate that object in code.

Review - Is Grokking Algorithms book by Aditya Bhargava worth it?

Hello guys, I have read many books on data structures and algorithms like Introduction to Algorithms by Thomas H. Corman and Algorithm design manual by Steve S.

Top 5 Books to Learn Groovy for Java Developers in 2025 - Best Of Lot, Must Read

Groovy is a programming language that is specially created for Java developers with a view to being a fast-paced, scripting companion to Java. It aims to increase the productivity of Java developers by simplifying Java code and removing unnecessary boilerplate.

Because of this property, Groovy is heavily used in unit testing of Java application. Some popular unit testing frameworks like Spock is also built on Groovy.
