10 Essential Tools Every Java Developers Should Know

Hello guys, we are already in the second month of 2019 and I am sure all of you have already made your goals about what to learn in 2019 and how to achieve them. I have been writing a series of articles to give you some ideas about the things you can learn and improve to become a better, all-round developer in 2019 like learning new programming languages, frameworks, and libraries. These three things are extremely important and help you to become a better Java developer but as some wise person said, "you are only as good as your tools", you should also look to upgrade your tools, learn new tools and improve your understanding of old tolls which are still going well.

Grokking Algorithms Book Review - Best Data Structure and Algorithm Book for Beginner Programmer and Computer Science Students

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. Skiena, so when I come to know about this book, I thought, just another book on algorithms, but I was wrong. This is not just another book on algorithms but one of the most interesting books you will ever read on Algorithms and Data structure. It doesn't cover all the data structure and algorithms you see in Computer Science but whatever it covers, it does really well and that's what matters most for beginner programmer or Computer Science students.

The year of 2017 was the year of releases for Java developer. With releases of JDK 9, Spring 5, Spring Boot 2.0 and Spring Security 5.0 there was so much to learn for Java developers and all at once, but like many others, I didn't make a good process and I am looking to turn it around in 2018. One of my top priority goal for New Year to learn new features of Java 9 as quickly as possible to write more about it. It's also important for you to learn Java 9 quickly to improve your career prospects.

Top 5 Spring Boot Features Java Developers Should Know

You might have heard about Spring Boot and it's magical powers about creating a Spring Web application in just under 140 characters which can be written in a tweet, but what that really means? What are those features which provide Spring Boot such power and make Spring application development so easy? Well, that's what you will learn in this article, but if you are in hurry let me tell you that you will learn about Spring Boot's auto-configuration, Starter dependencies, Spring Boot CLI, Actuator and Spring Initializer feature in detail. These are the feature which takes away most of the pain and friction associated with writing Spring-based Java web application.

Top 5 Courses to Learn Data Structures and Algorithm for Programmers and Computer Engineers

Both Data Structures and Algorithms are one of the most important topics for programmers. The best thing about them is that they never get out-of-date and any investment you made in terms of time and money will pay rich dividends for a long time. I have also found that people good at algorithms and data structures are often a better programmer than others. They tend to improve your programming skill and coding sense and that's the main reason I suggest all kinds of programmers, from junior to senior to spend some time revising, refreshing and honing your data structure and algorithm skills. Most of us first heard about them in school and colleges but didn't understand at that time. At least I can say that for me. I first heard about array and linked list on my engineering college.

Top 5 Object Oriented Programming and Design Courses in Java - Best of Lot

There is no doubt that Object-oriented programming is a pillar of software development and also one of the reasons for the huge success of Java. Good knowledge of Object-oriented programming helps you to create better software. It also helps you to communicate your ideas better with your team members and fellow programmers. Despite being such an important technology, it's difficult to find programmers who understand OOP well. Many programmers just think that OOP is nothing more than Abstraction, Inheritance, Encapsulation, and Polymorphism, without truly understanding these concepts and mastering them.

10 Object Oriented Design Principles Java Programmer Should Learn in 2019

The Object-Oriented Design Principles are the core of OOP programming, but I have seen most of the Java programmers chasing design patterns like Singleton pattern, Decorator pattern, or Observer pattern, and not putting enough attention on learning Object-oriented analysis and design. It's important to learn the basics of Object-oriented programming like Abstraction, Encapsulation, Polymorphism, and Inheritance. But, at the same time, it's equally important to know object-oriented design principles. They will help you to create a clean and modular design, which would be easy to test, debug, and maintain in future.

Top 6 Free Online Database and SQL Courses for Programmers

Hello guys, we are already in the first week of New year and everyone is talking about their goals to improve them as a better person, a better programmer, or get better health. If you have also made your goal and one of them is to improve your SQL skill then you have come to the right place because I am going to share some of the free courses to learn and master SQL this year. As you already know, SQL is one of the essential skill and much more important than any fancy library or framework you are thinking to learn.  If you ask me which two skill every programmer should have, I would say SQL and UNIX, these two have survived for a long time and will survive for many coming decades. SQL is also very interesting, once you get a hang of it, you would love to write queries and analyzing the performance of your queries.

Is "Java Concurrency in Practice" Still Valid in the Era of Java 8 and 11?

One of my reader Shobhit asked this question on my blog post about 12 must-reads advanced Java books for intermediate programmers - part1. I really like the question and thought that many Java programmers might have the same doubt whenever someone recommends them to read Java Concurrency in Practice. When this book came first in 2006, Java world was still not sure of about new concurrency changes made in Java 1.5, I think the first big attempt to improve Java's built-in support for multi-threading and concurrency. Many Java programmers were even not aware of new tools introduced in the API e.g. CountDownLatch, CyclicBarrier, ConcurrentHashMap and much more. The book offered them the seamless introduction of those tools and how they can use them to write high-performance concurrent Java applications.

10 Free Courses to Learn Python in Depth

There is no doubt that Python is currently the world's #1 programming language and the biggest advantage of that is it's bringing more and more people into the programming world. In recent years, I have seen more people learning Python than any other languages, yes, not even JavaScript. Many of them learning Python to explore some awesome Data Science and Machine learning libraries provided by Python. Some people are also learning Python for web development and there are still many developers who are learning Python for scripting and automating trivial tasks. It doesn't matter why you are learning Python at this moment, it's a great thing in itself that you have decided to learn Python.

Thread, Code and Data - How a Multithreading Java Program Actually Run

There are certain things, which you don't learn on academics or training class, you develop those understanding after few years of work experience, and then you realize, it was very basic, how come I had missed that all those years. Understanding of how a multi-threaded Java program executes is one of such things. You definitely have heard about threads, how to start a thread, how to stop a thread, definitions like its independent path of execution, all funky libraries to deal with inter-thread communication, yet when it comes to debugging a multithreaded Java program, you struggle.

Top 5 Free Kubernetes courses for DevOps Engineers and Programmers

Hello guys, DevOps is becoming an essential skill in today's Programming and Software Development world and Kubernetes is an important concept and tool for DevOps Engineer. It takes container based deployment to another level and allows you to manage it on the scale. You can use Kubernetest to scale your container environment or let Kubernetes do all the work for you by leveraging its auto-scaling feature. Many DevOps beginners think that Docker and Kubernetes are the same but they are not. Docker provides a container to deploy your application and commands to interact with those but container but Kubernetes is actually a container management technology, which decides how many containers are needed and deal with other management aspects.

Difference between @ContextConfiguration and @SpringApplicationConfiguration in Spring Boot Integration Test

Even though both @ContextConfiguration and @SpringApplicationConfiguration annotations are used along with SpringJUnit4ClassRunner to specify how to load the Spring application context, there is a subtle difference between them. Although @ContextConfiguration does a great job in loading application context it doesn't take full advantage of Spring Boot features. Spring Boot applications are ultimately loaded by either SpringApplication ( in case of the JAR) or SpringBootServletInitializer. This class not only loads the application context but also enables logging and loading of external properties specified in application.properties or application.yml file, and other features of Spring Boot framework, which is not loaded or enabled by the @ContextConfiguration annotation. 

Top 5 MongoDB Online Training Courses for Web Developers

MongoDB is one of the leading NoSQL databases and it was on my radar for a long time but I never get a chance to learn or work on it, but Recently I got an opportunity to use MongoDB for one of our projects and I learned a lot on the way. In this article, I will introduce MongoDB and how to learn MongoDB so that you can use it in your project. In this article, I will share some of the online courses which I have taken to understand everything up to the basic CRUD (Create, Retrieve, Update, Delete) operations on MongoDB. I have also read a couple of books and followed some tutorials but these courses were my main source to learn Mongo DB.
