Top 5 Books to Learn Unit testing, JUnit and TDD in Java - Best of Lot

Hello guys, If you done some professional Java development then you know that Unit testing is a very, very important thing to learn to adapt. I would say this is the single most practice in my book, which differentiates an excellent programmer with a professional programmer. It's one way you can see how disciplined a programmer is? 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.

How to Crack Microsoft AZ-103 Azure Administrator Associate Exam Certification in 2020

Hello guys, if you are looking for cloud certifications in 2020 then Microsoft Azure Cloud certification can be a great addition in your profile.

These are the replacement of 70-535 for new role-based Microsoft Azure Administrator Certification. On May 1, 2019, both AZ-100 and AZ-101 exams have been replaced by the AZ-103 exam.

Top 20 Libraries and APIs Java Developer should know

One of the traits of a good and experienced Java developer is the extensive knowledge of API, including JDK and third-party libraries. I spent a good deal of time learning API, especially after reading Effective Java 3rd Edition, where Joshua Bloch has advised us to use existing API for development rather than writing new pieces of code for common stuff. That advise making sense to me because of the testing exposure these 2nd party libraries get. In this article, I am going to share some of the most useful and essential libraries and API, a Java developer should be familiar with. Btw, I am not including frameworks e.g. Spring and Hibernate because they are pretty well known and have specific features.

Top 5 Books to Learn DevOps for Developers - Best of Lot

Hello guys, DevOps is one of the in-demand skills for experienced developers. It also offers a career path for senior developers who don't want to go to project management and want to remain technical and close to the code, but what is DevOps? and how can you learn DevOps? In the past, I have shared some of the best DevOps courses and a complete DevOps Developer RoadMap, and in this article, I'll share the best books to learn DevOps for developers, but before that let's understand What is DevOps?  It is nothing but is an integration of the word development (Dev) and Operations (Ops). Development here refers to software development, I mean the process of writing code, unit testing, debugging and running source codes to create software. While Operations are Information Technology Operations like deployment, support, and creating new environments.

Difference between Dependency Injection and Factory Design Pattern in Java Spring

Learning a Programming language like Java or Python is easy, but writing production-quality code is difficult. Coding is as much art the Science behind it. To write good code, you need to carefully design your classes, their dependency, and how to use that. This is important so that it can survive the constant change throughout his lifetime. If you have been coding for some time, then you know that SOLID principles and Design Patterns help you to write better code. This is obvious because they are proven the solution to some common problems software developers face all around the world. But, knowing just the design pattern is not enough, you also need to learn using the right design pattern in the right place.

10 Reasons to create Online Courses as a side hustle in 2020

These days everyone is turning to online courses to learn almost anything from programming languages like Java to Python, from a framework like React and Vue.js to skills like Data Science and Machine learning. Online teaching and learning have completely changed the way how people acquire knowledge. It was always said that a picture is worth more than 1000 words and online courses, particularly interactive and visual courses use them at their full potential. I often receive queries from my readers, fellow bloggers, and programmers about creating a side income apart from their full-time job, etc. Until last year, my advice to them was to create a blog, but now I am telling them to create an online course now, in 2020.
