Linux is one of the most popular operating systems to run server-side applications. I have seen almost all Java applications running on Linux, barring a couple of them, which runs on Windows as service. If you take out standalone apps like IDEs or tools, most of the real-world Java applications run on Linux, e.g., payment gateways, trading systems, and other financial applications. That's why it's essential for any programmer, IT professional, or a developer to learn and understand Linux, both the operating system, as well as the command line.
Top 10 Spring MVC and REST Annotations with Examples for Java Programmers
Hello guys, welcome to my third article on exploring essential annotations from the Spring framework, the most popular framework for Java development. In the first article, I have shared some of the most useful Spring Framework annotations, which were based upon Core Spring functionalities like dependency injection, inversion of control, and configuration, and in the second article, we have learned about important Spring Cloud annotations like @EnableConfigServer, @EnableEurekaSever, and @EnableDiscoveryClient.

Top 5 Spring Framework Books for Java developers (Includes Spring Security and Spring Boot) - Best of lot
Spring framework is one of the most famous structures in the Java world, which used to develop Java application, both core Java and web application. It is also one of the most job oriented skills for Java developer; hence many beginners and intermediate Java programmers try to learn Spring framework on their own. Though there are some excellent Spring training courses available online, books are still the most popular and preferred way to learn Spring frameworks like Spring core, Spring Boot, Spring MVC, Spring Batch, or Spring Security. I often receive queries for Spring book recommendations e.g., which Spring book is suitable for beginners, or which Spring book is good for intermediate and advanced developers, which book should I read to learn Spring boot, Spring Cloud, Spring Batch, or Spring security, etc.?
Top 13 Java Serialization Interview Questions and Answers for Beginners and Experienced Developers
There is no doubt that Java is vast and there are some Java topics which many Java developers rarely explore. Serialization is one of them which is rarely used in practice but quite popular during Java interviews. It's also one of the difficult topics to master and that's why I am going to share some frequently asked Java Serialization interview questions in this article. I don't know why people ask so many questions from Selrization if not everyone uses it but I have always seen some questions from Java realization. These are also the toughest and confusing questions to answer and more likely cannot be answered by an average Java developer.
How to swap two Integers without using temporary variable in Java?
One of the oldest trick questions from a programming interview is, How do you swap two integers without using temp variable? This was first asked to me on a C/C++ interview and then several times on various Java interviews. The beauty of this question lies both on the trick to thinking about how you can swap two numbers without the third variable, but also problems associated with each approach. If a programmer can think about integer overflow and consider that in its solution then it creates a very good impression in the eye of interviewers.
