10 Ways To Become A Perfect Java Programmer 2021

10 Ways To Become A Perfect Java Programmer 2021

Hey friends, there’s another year coming up and it’s a nice time to reflect and look back at what you did last year and what you should have done differently. If you have not done so, this will allow you to build your targets for 2021. Your greatest obstacle, as a programmer, is to keep yourself up to date.

Technology is improving very quickly, and each year you can see the latest edition of your favourite computer language and frameworks. The last few years have introduced abundant updates for Java programmers and provided a challenge to keep up-to-date with the latest Java release every six months, Spring 5, Spring Security 5, and Spring Boot 2, etc.

I assumed Java 11 was the latest when I learned last year, and before I even finished learning Java 11 full, Java 13 and Java 14 were out already. So, they arrived very quickly but came with a number of great features such as local variables var, API enhancements, GC enhancements, greeting handshake Thread Local, and many others.

I’ve reported them here, and I’m very excited about using them in 2021. I won’t understand all the updates in Spring 4.0 and Spring Protection 4.0, my project used only Spring Security 3.1, and now we just have versions 5.0 for both Spring and Spring security. The very same goes for the Spring framework and Spring Security.

In the last couple of years, my have to learn speed has slowed down considerably and I have not managed to stay up-to-date with either the newest and best as I still want to get acquainted with Git, JavaScript frameworks such as Angularjs and React, updated unit and integration testing space updates and a new edition of a common framework, e.g. Winter, Security Spring, and New Boot Spring.

What Java developers should learn?

Here seems to be my list of material that 10 TIPS TO BECOME A PERFECT JAVA PROGRAMMER 2021 to become a stronger Java developer and move their career in the right direction:

1. Learn Java 8:

That most Java development positions now need Java 8 skills, and it will be difficult to do well and do well in your Java interviewing if you’re not using them. Presently, until you have created your intention to learn Java 8 but worried over where to begin, I recommend that you search Udemy’s Full Java MasterClass, which will help educate you on all the fundamentals of Java 8 functionality and other additional features implemented in Java 9, 10, 11, 12, 13, 14, 15, and perhaps very soon in Java 16. And here are some relevant new Java features that you can learn.

2. Learn the JVM’s Internals:

You are required to grasp Java Virtual Machine (JVM), a vital aspect of JRE, also as a Java novice (Java Runtime Environment). JVM comprehension requires acknowledging Java as a programming language even more. JVM can support you during the implementation phase in solving complex problems.Learn the JVM's Internals

3. Learn APIs and Libraries

You might just have observed their extensive understanding of the Java Ecosystem if you have collaborated with great Java programmers and APIs are a key component of it. Java has been the most famous and intelligent programming language in the world and there are tonnes of library services and APIs accessible to do almost all possible things. You weren’t supposed to understand all of them, of course, but you must know some main APIs such as JSON processor APIs such as Jackson and Gson, XML processing APIs such as JAXB and Xerces, Unit checking libraries such as Mockito and JUnit, etc.

You can gain knowledge, or at least get an overall view of them if you do not even know them. Every Java developer must know my list of 20 Java libraries to start with, which contains libraries from key areas such as parsing, bytecode manipulating, competition, collections, etc.

4. Learn DevOps Tools:

Learning of DevOps is important for a current Java developer. He must be associated with integrated development and application development at least and how Jenkins helps to do it. For senior Java programmers, who are also responsible for implementing coding best practices and designing environments, developing scripts and instructions, this becomes much more important.

I also recommend that you spend some time with Maven to Jenkins and learning much about DevOps in general and resources like Docker, Ansible, Kubernetes, etc. Learning DevOps: CI/CD with Jenkins utilizing Pipelines and Docker in Udemy is probably the most effective course to proceed with if you need any tools. Not only can you read in detail about CI and CDs, but also about Maven and Jenkins.

5. Learn Spring Framework:

Nowadays, understanding the Spring framework is almost necessary for a Java developer since most enterprises tend to build using Spring frameworks such as Spring MVC, Spring Cloud, and Spring Boot to create a web server, REST APIs, and microservices. It also supports best practices such as dependency injection and makes the program more testable, which is a crucial modern-day tech necessity.

But if you’re a new Java developer, then I recommend that you start learning the fundamentals of this amazing platform with these Java and Spring tutorials, and when you’re already comfortable with Spring, then you can explore Spring Boot and Spring Cloud to build Java applications for the next generation.

6. Learn Design Patterns:

If you write a Java program from scratch, then you write object-oriented code much of the time, and architecture patterns are tried and tested for typical solutions to problems. You make your program more stable and easier to modify in the future by understanding and implementing them into your code. It also increases overall code quality and documentation since architecture structures are also common to other Java developers. They would, however, very easily grasp the solution. But don’t just concentrate on the aspect of the code, grasp and be innovative with the spirit. To rewrite patterns, use Java 8 features such as Lambdas and Streams.

7. Learn Unit Testing:

If a successful Java developer is distinguished from an average Java developer by one common occurrence, it is unit testing abilities. A strong and competent Java developer will often write test scripts for their code and you’ll see it from their code and tests whether they’re such a rockstar programmer. Testing has also made great strides, with many platforms open to Java developers for unit testing, integration and system testing, and automated testing. You will spend a good deal of 2018 honing your Java testing ability, but JUnit is the perfect library, to begin with among those who are new to the Java environment and unit testing.Learn Unit Testing

8. Learn Your IDE Better:

Among the most significant characteristics of better Java programmers is that their resources are really good. Not only do they know more instruments than an ordinary designer, but they know their software well as well. Though the most effective techniques for a Java programmer are IDEs like Eclipse, NetBeans, and IntelliJ Concept, it makes sense to invest some time learning something about them.

9. Learn Microservices and cloud:

Architecture is continuously evolving and many enterprises are switching to microservices from monolithic applications. In order to benefit from this recent surge, it’s highly important for Java developers to learn Microservice architecture and how to build Microservices in Java. Luckily, Spring Boot and Spring Cloud are supported by the spring framework, which greatly simplifies Java microservice growth. Master Microservices with Spring Cloud and Spring Boot is a good one, to begin with when you are planning for a course.

And, if you like books, I recommend you check out Josh Long’s Cloud Native Java, which offers a detailed guide to creating cloud Java applications.

10. Learn Kotlin:

I reading a book called The Well-Grounded Java Programmer a couple of months ago, which stressed the benefit of being a polyglot programmer. It encouraged me to learn Scala, and because of its expanded use in constructing scripts and test automation, I even tried Groovy later. The experience has helped a lot, which is why I advise developers of Java to learn the latest language for JVM.

I’ve previously written a blog post about it in 3 JVM languages that Software developers can master in 2018, so if you’re in a rush, just learn Kotlin. Not only will it increase your productivities, but it will also actually benefit you get into the implementation of Android. Whether you are desperately searching for some good resources to learn Kotlin in 2018, then here is a collection of Kotlin courses, to begin with.Kotlin
