Top 3 Programming Languages Java Programmers Should Learn in 2019

If you are a Java programmer and thinking to learn some news programming languages to expand your knowledge and skill, but not sure which programming language is better for you then you have come to the right place. In this article, I'll share 3 programming languages Java developers should learn in 2019 and why they should learn them. There is no surprise that all of these programming languages are JVM based programming languages but they all have different qualities which makes them unique and useful for a certain task. Also, being a Polyglot developer is good quality and often valued high on interviews. It also expands your thinking because different programming languages have different features which make certain things really easy.

10 Free Python Courses for Programmers and Developers

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.

How to implement Command design Pattern in Java with Example

Hello guys, it's been a long since I have shared a Java design pattern tutorial. I did share some courses to learn design patterns but haven't really talked about a particular design pattern in depth. So, today, we'll learn one of the important design pattern, which is often overlooked by Java developers. Yes, I am talking about the Command Pattern which can help you write flexible, loosely coupled code for implementing actions and events in your application. In simple words, the command design pattern is used to separate a request for an action from the object which actually performs the action. This decoupling between Invoker and Receiver object provides a uniform way to perform different types of actions. This decoupling is achieved using a Command object, which is usually an interface with methods like execute()

Top 5 Selenium + Cucumber Online Courses for Java Developers and Automation Testing Programmers

The days of manual testing is limited as more and more companies are shifting towards Automation testing. This means all manual testing QAs needs to learn new test automation skills like Selenium, Cucumber, JUnit, Mockito, and TestNG to give their career a boost. If you are manual testers or non-programming testers interested in learning test automation, a Java developer who wants to write a better integration test, or a freshers/graduates who want to kick start their career in automating testing then you have come to the right place. In this article, I am going to share some of the best courses to learn Selenium Webdriver with Java and other automation testing tools like JUnit, Cucumber etc.

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 an art as much the Science behind it. In order 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 of 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.

Top 5 Data Structures and Algorithm Online Courses for Programmers

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.
