Java has been very popular with developers and employers alike for more than 25 years, and this popularity has only increased. It's a nice moment to look back and reflect on what you've accomplished in the previous year and what you might have done differently.
This will assist you in developing your objectives for the years 2021-2022. As a programmer, one of the most difficult tasks is to stay up with the latest technology. Technology advances at a breakneck pace, and you can expect a new version of your preferred programming language and framework to be released at least once every year.
Java is used worldwide for addressing a variety of issues
Developers may address issues with the assistance of hundreds, if not thousands, of frameworks, libraries, and other tools available in Java. Only a very tiny proportion of developers encounter issues that are completely new to them. Most likely, someone else has already addressed your issue and developed one of the tools we mentioned above to aid them in their endeavor. As a result, you may make use of them as well; there is no need to recreate the wheel.
Java provides a plethora of very useful tools and frameworks that you may put to good use.
In the past couple of years, there have been many changes, which has made it difficult for Java developers to keep up with the latest Java versions, which are released every six months.
1. Become familiar with Java Performance Tuning.
One area of expertise that stands out as missing is knowledge and understanding of JVM internals, garbage collection behavior, and Java execution optimization.
As your Java experience grows and you go from a junior Java engineer to a senior Java engineer with more than 5-6 years of experience, it is expected of you to have a thorough understanding of Java's fundamentals as well as specific insights into its details.
2. Become familiar with Java Network Programming.
In addition, one thing I've learned from talking to others is that Java developers should brush up on their attachment programming and systems administration fundamentals to be more competitive.
Some of them even struggle to understand the main differences between TCP and UDP, which is extremely essential, making it difficult to recruit any Java designers with more than 2-5 years of expertise.
You should study at least one excellent book on Java systems administration, NIO, and attachment programming if you believe that you have not had enough opportunity to learn it or that you do not need it since you are a Java web engineer working with JSP, Servlet, and JSF.
3. Selenium is the third element.
Java developers should be familiar with the Selenium web driver, which is one of the technologies that will be used in 2021. Web application testing using Selenium is made possible via the use of test frameworks. The API provided by the Selenium Web Driver is free and open-source. It contains web application automation capabilities, as well as other features. It is recommended that you continue reading Getting Started to learn how to install Selenium and effectively utilise it as a test automation tool, as well as how to scale basic tests like this to run in big, dispersed environments across a variety of browsers and operating systems.
4. Become acquainted with frameworks
Spring, Hibernate, and Spring Boot are some of the technologies that junior Java developers are expected to be familiar with. Being able to do independent research into the various technologies is not a simple job; nevertheless, it is feasible, at least at the most basic level.
Where can you get some hands-on experience with Java programming?
You should code as much as possible every day, if at all feasible. Following are the three greatest sites for limitless coding that we have come across so far.
1. It's called CodeGym, and it's an online gamiﬁcation course on Java programming that's 80 percent practice and 20 percent theory. The course has been tailored to accommodate students who are studying Java for the first time and contains programming assignments from the very first session.
2. CodeCademy is a course that will assist you in gaining valuable technical skills for the actual world of programming while also providing you with a great deal of practice.
3. This is a great resource for powerful programming practice and refining your coding abilities in preparation for after you master Java basics and have acquired the required minimum of programming experience (Codewars).
Despite the fact that programmers are often portrayed in popular culture as cranky guys with lumberjack beards who would do nearly everything to avoid interacting with people, this is not the case. Or, at the very least, it is not entirely accurate. Unless you interact with some other students and experienced Java programmers India, you will not be able to go through the learning process.
