Top 5 Java Programming Courses for Beginners to Learn Online - Best of Lot

If you are a computer science graduate or someone who wants to learn Java and looking for some awesome resources e.g. books, tutorials, and online courses then you have come to the right place. In the past, I have shared some great books and tutorials to learn Java and in this article, I am going to share some of the best Java courses beginners can join to learn Java. One of the main problems with learning Java is to keep pace with the increasing number of releases. For example, Java 8 was released in 2014 which completely changed how Java is written and now within the last 6 month, we have two major Java releases in form of Java 9 and Java 10. But the good thing is that the core of Java is still the same and all its releases are backward compatible.

Earlier with groundbreaking changes in the form of Enum, Generics, and Autoboxing in Java 5, performance improvement with Java 6, functional programming using the lambda expressions in Java 8, and Google's choice of language for Android apps development keeps Java as a front-line programming language.

Top 5 Courses to Learn Jenkins for DevOps Engineers and Java Programmers

In today's world of Agile and DevOps, Jenkins has become an indispensable tool for both Java programmers and DevOps engineers. Jenkins allows you to set up continuous integration (CI) and continuous deployment (CD) pipeline, which reduces risk on Software development and delivery. This means hassle-free development and deployment. It also means quicker feedback because as soon as a commit has been made into a source control system like Git, Jenkins can start building artifacts and running unit tests. If the build failed due to an issue or if a unit test doesn't pass, you will receive an email instantly. This quick feedback loop ensures that your codebase remains error free.

How to find and kill a Process Listening on a port in Linux? netstat and lsof command examples

In Linux, many times, you want to find out the PID of a process which is listening on a port e.g. if multiple tomcat servers are running on a host and you have to kill that process, but in order to kill that process you need the process id, how do you find the PID of the tomcat listening on port 8080? There are many Linux commands to find the process using a specific port, but I'll share what I use. I always use the netstat command with -p option, which displays process id of the process listening on a port. Btw, netstat is not the only command to find all processes using a particular port, you can also use the lsof command for the same purpose.
