Hello friends, another year is approaching, and it’s a good time to reflect on what you did last year and what you should have done differently. If you haven’t already, this will allow you to set goals for 2021. As a programmer, the most difficult challenge is staying current.
Technology advances at a rapid pace, and each year you can see the latest version of your favourite computer language and framework. The last few years have seen a flood of updates for Java programmers, making it difficult to keep up with the latest Java release every six months, Spring 5, Spring Security 5, and Spring Boot 2, among other things.
When I first started learning Java last year, I assumed it was the most recent version, but before I finished, Java 13 and Java 14 were already available. As a result, they arrived quickly but with a slew of great features like local variables var, API enhancements, GC enhancements, greeting handshake Thread Local, and many more.
I’ve reported them here, and I’m looking forward to putting them to use in 2021. I won’t be able to understand all of the changes in Spring 4.0 and Spring Protection 4.0 because my project only used Spring Security 3.1 and now we only have versions 5.0 of both Spring and Spring Security. The same is true of the Spring framework and Spring Security.
Top 10 Ways To Become A Perfect Java Programmer In 2022
In recent years, my desire to learn has slowed significantly, and I have not been able to keep up with the latest and greatest as I still want to Winter, Security Spring, and New Boot Spring.
What should Java developers learn?
Here appears to be my list of material that 10 TIPS TO BECOME A PERFECT JAVA PROGRAMMER 2021 can use to become a stronger Java developer and advance their career:
1. Learn Java 8
That most Java development positions now require Java 8 skills, and that if you aren’t using them, it will be difficult to do well and do well in your Java interviews. Currently, if you have decided to learn Java 8 but are unsure where to start, I recommend searching Udemy’s Full Java MasterClass, which will help educate you on all the fundamentals of Java 8 functionality as well as other additional features implemented in Java 9, 10, 11, 12, 13, 14, 15, and possibly very soon in Java 16. And here are some new Java features that you should be aware of.
2. Understand the Internals of the JVM:
As a Java novice, you must understand the Java Virtual Machine (JVM), a critical component of JRE (Java Runtime Environment). Understanding the JVM necessitates a greater appreciation for Java as a programming language. JVM can help you solve complex problems during the implementation phase. Understand the Internals of the JVM
3. Understand APIs and Libraries
If you’ve worked with great Java programmers, you may have noticed their extensive understanding of the Java Ecosystem, and APIs are a key component of it. Java is the most well-known and intelligent programming language in the world, and there are a plethora of library services and APIs available to do almost anything. Of course, you are not expected to understand all of them, but you must be familiar with some key APIs such as JSON processor APIs such as Jackson and Gson, XML processing APIs such as JAXB and Xerces, unit testing libraries such as Mockito and JUnit, and so on.
You can learn about them or at least get a general sense of them if you don’t know anything about them. Every Java developer should be familiar with my list of 20 Java libraries to get started with, which includes libraries from key areas such as parsing, bytecode manipulation, competition, collections, and so on.
4. Learn DevOps Tools:
A current Java developer should be familiar with DevOps tools. He must be familiar with integrated development and application development, as well as how Jenkins aids in these processes. This is especially important for senior Java programmers who are also responsible for implementing coding best practises, designing environments, and developing scripts and instructions.
I also recommend that you spend some time learning about Maven to Jenkins and DevOps in general, as well as resources like Docker, Ansible, and Kubernetes. If you need any tools, Learning DevOps: CI/CD with Jenkins utilising Pipelines and Docker on Udemy is probably the best course to take. You can learn everything there is to know about CI and CDs, as well as Maven and Jenkins.
5. Understand the Spring Framework:
Nowadays, understanding the Spring framework is almost mandatory for a Java developer because most enterprises build web servers, REST APIs, and microservices using Spring frameworks such as Spring MVC, Spring Cloud, and Spring Boot. It also supports best practises like dependency injection and makes the programme more testable, which is an important modern-day technology requirement.
But if you’re a new Java developer, I recommend starting with these Java and Spring tutorials to learn the fundamentals of this amazing platform, and once you’re comfortable with Spring
6. Understand Design Patterns:
When you write a Java programme from scratch, you write object-oriented code the majority of the time, and architecture patterns are tried and tested for typical problem solutions. Understanding and incorporating them into your code makes your programme more stable and easier to modify in the future. It also improves overall code quality and documentation because architecture structures are shared by all Java developers. They would, on the other hand, quickly grasp the solution. But don’t just focus on the code; understand and be creative with the spirit.
7. Learn Unit Testing:
If there is one thing that separates a successful Java developer from an average Java developer, it is unit testing abilities. A strong and competent Java developer will frequently write test scripts for their code, and you can tell whether they’re a rockstar programmer by looking at their code and tests. Testing has also advanced significantly, with numerous platforms available to Java developers for unit testing, integration and system testing, and automated testing. You’ll be spending a lot of 2018 honing your Java testing skills, but JUnit is a great place to start for those who are new to the Java environment and unit testing. Understand Unit Testing
8. Learn Your IDE Knowledge:
One of the most important characteristics of good Java programmers is that they have excellent resources. They not only know more instruments than the average designer, but they also know their software well. Though IDEs such as Eclipse, NetBeans, and IntelliJ Concept are the most effective techniques for a Java programmer, it makes sense to spend some time learning about them.
9. Understand microservices and the cloud:
Architecture is constantly evolving, and many businesses are shifting away from monolithic applications and toward microservices. To capitalise on this recent surge, Java developers must first learn Microservice architecture and how to build Microservices in Java. Fortunately, the spring framework supports Spring Boot and Spring Cloud, which greatly simplifies Java microservice growth. When planning a course, Master Microservices with Spring Cloud and Spring Boot is a good place to start.
10. Learn Kotlin:
A few months ago, I read a book called The Well-Grounded Java Programmer, which emphasised the importance of being a polyglot programmer. It encouraged me to learn Scala, and because of its extensive use in scripting and test automation, I later tried Groovy. The experience has been extremely beneficial, which is why I advise Java developers to learn the most recent JVM language.
If you’re in a hurry, just learn Kotlin. I’ve previously written about it in 3 JVM languages that Software developers can master in 2018. Not only will it increase your productivity, but it will also help you get started with Android implementation. If you’re looking for some good resources to learn Kotlin in 2018, here’s a list of Kotlin courses to get you started. Kotlin
