10 Tips to Become a Better Java Developer in 2019

As a Java programmer and a blogger, I receive many emails regarding how to boost themselves in Java programming.
So through this article, I collected some of the best tips for Java programmers to enhance themselves, upgrade their knowledge of Java programming, and increment their incentive for future career development.  So Let’s jump to see what are the essential facts to be considered for Java programmers in 2019. You can take inspiration from these plans to make your own goals.

Learn Java Performance Tuning

In the last a few years, I have taken more than 50 interviews for senior Java developers, and one skill that I observe lacking is knowledge and comprehension about JVM internals, GC conduct, and custom java development performance tuning.



Learn JVM Internals

As your Java skill develops and you promoted to a senior Java developer with more than 5– 6 years of experience, it’s required from you to know both the master plan and the little insights about Java’s fundamentals.
Suppose you are getting a thing, at that point, you should go for a decent book on JVM internals, and performance tuning, e.g., Scott Oaks’ smash hit Java Performance the Definitive Guide.  I have been reading it for quite a long time and still allude it at whatever point I get time. My goal is to peruse it again this year.  On the off chance that you prefer online courses over books, I suggest you search for Understanding the Java Virtual Machine arrangement of seminars on Pluarlsight, which clarifies memory the executives, class loading, Security, and Reflection.

Regular Coding for 2 hours

Something else I saw a year ago is that as your experience develops, you invest your energy more in coordination, answering to messages, being a catalyst, investigating, tutoring, and by and large being a project supervisor sort of individual.

Code, Code, and Code

What you deserted is coding, which is the absolute most vital skill for a software engineer.  If you feel that you are not doing enough coding, make a goal to code each day. For this, you can build small software or work for your project.

Check Your Java Application Skill

This tip is joined with the main advice about reading a decent book on JVM internals and performance tuning. Just reading the book won’t be enough. You need to apply that knowledge in your live project. I recommend you profile your Java application, at any rate once per month and invest a decent measure of energy understanding and analyzing the outcomes.

You can likewise take a heap dump of your Java procedure or, if you had an ongoing accident, take that heap dump and discover which question is taking the more significant part of your memory.
What is the reason? What will occur if other 100K new clients access your application? On the off chance that you can answer every one of these inquiries serenely, you are fit as a fiddle. On the off chance that you require some direction on tackling memory and CPU issues, I propose you investigate Understanding and Solving Java Memory Problems by Richard Warburton.

Take an interest in Coding Challenges

This goal is, once more, to some degree identified with our second resolution — write code each day for 2 hours. Now and again, you don’t have enough possibilities in your live project to code.  On the off chance that you are starving for challenging code, there is nothing superior to taking an interest in programming and coding challenge.  There are numerous sites on the web that have programming challenges and give you the chance to test your skills, yet TopCoder is necessarily the best.

If you are searching for some extreme programming challenges, you can likewise look at my rundown of good sites to practice coding.



Learn Network Programming in Java

One all the more thing I have gained from meeting individuals is that Java developers need to enhance their socket programming and systems administration fundamentals.  I have made numerous inquiries from my rundown of Java organizing programming questions, however, most developers neglect to answer a large portion of them.

Some of them even battle to plot the critical contrasts among TCP and UDP, which I thought was excessively fundamental, making it impossible to solicit any Java developer from 2– 5 years of experience.  In the event that you feel that you have not gotten enough chance to learn socket programming in Java or that you don’t have to on the grounds that you are Java web developer working with JSP, Servlet, and JSF, at that point I propose you read no less than one great book on Java systems administration, NIO, and socket programming.

One book I very suggest is TCP/IP Sockets in Java, Second Edition, Practical Guide for Programmers. It’s anything but confusing to peruse, intriguing, and a decent method to take in the fundamentals of socket programming.
