Technology evolution is everywhere. There is no question in saying Java is continuously growing. There are over 9 million Java developers, who prefer to use java. You can imagine the demand globally. Generally, software developers choose Java as a foundational coding language. Java is a very basic programming language but professionals prefer to learn advanced skills of java. Currently, Java programming language is the first choice of developers for developing Android apps. Java developer skills have been in demand since 1995, as it is a fast, reliable and secure programming language.
Java Developers Skills You Need to Learn for Your Career Growth:
1. Deep-Dive into Primitive Skills:
If you are looking to step foot in java developing, you first need to understand the key skills of java. It is a universal fact that to develop various types of software that starts from desktop to mobile application, from web application to cloud system. Java is also known as an all round development language.
If you want to explore your skill in Java, Here’re the most important the following java technologies:
# Java is an object-oriented programming language, it is more efficient and straightforward method of programming.
# Java includes relational databases like MySQL, PostgreSQL and MariaDB. With the help of Java writing MySQL queries will be handy.
# There are popular versions of Java that include Git and BitBucket.
# Java supports web frontend technologies like HTML, CSS and jQuery.
2. Java Tools, Languages and Frameworks:
When you are relying on Java, there are few things you need to know about. In Java, there are two types of framework i.e. Java SE and Java EE where the Java developers need to have expertise.
Other than framework there are alternative tools like Servlets, Java Beans, Java Server Pages and technology frameworks that make a difference. Java also includes Hibernate Framework too which is an additionally popular
framework used for projects.
Other than framework you must also understand:
# Markup languages like XML and JSON.
# Web technologies like HTML, CSS, JavaScript & JQuery.
# It also builds tools like Maven & Gradle.
# OOP(Object Oriented Programing) concept and design patterns.
With the basic understanding & features, it is not tough to learn the popular java programming language. As java is fit for all types of development platforms.
3. Combination of Android & Kotlin:
When you develop applications for Android and iOS, it is mandatory to be a pro in Java development. Kotlin is the altered version of the Java Programming Language. It seems that it is important to familiarize yourself with Kotlin as it will enhance your skill in future.
Nowadays, Android developers are slowly and gradually drifting to Kotlin as a modified Java Language. If you want to become an expert Java developer you must know both Java and Kotlin.
4. Spring Framework:
This is the most common tool for development. It is important to know about Spring Boot, Spring MVC and Spring Cloud as it is essential for website application development.
As per the researchers, there are more than 2000 websites that are developed by using Spring framework. Spring Framework is usually built on Model-View-Controller (MVC) architecture which divides process, sectors and representations.
5. Tech DevOps:
Currently, DevOps is the area where there are a lot of development and automation coding has been done. Because companies are moving towards DevOps and doing continuous integration + deployment.
Knowledgeable developers who execute best coding practices would know how to create manuals and scripts. Having sound knowledge of Kubernetes, Docker, Chefs, etc. tools is necessary for DevOps.
6. SQL Programming Language:
This is the first essential skill for every developer. As data is the primitive skill for any program development, SQL is not easy for analyzing the data. Developers can not develop a program without learning SQL programming language.
7. React or Angular:
Whether you are a Java developer or any other programming language developer, it is mandatory to diversify the needs of businesses and to fulfill requirements.
React is an open-source JavaScript library mainly used by the frontend developer. React follows only one principle “learn once, write anywhere”. React is always managed by community or individual developers.
Angular is a component-based framework for developing scalable web pages. Angular is the platform that is built on the typescript. Angular has a connection of well-integrated libraries and features which includes client-server communication, routing and much more. Learn more here Angular vs. React: How to Make a Right Choice?
8. Unit Testing:
Your application will grow day by day. It becomes mandatory to maintain the data and write automated tests that encompass a unit and integration test which is required for an application. Java is the programming language that doesn’t have deployment and assembly of an application fast.
For making application more reliable, Unit testing tool comes into the application i.e. JUnit and Testing come into play. The tools used in the unit testing always speed up the writing of automated tests, offer an easy syntax and provide you with instant feedback on passed tests.
9. Microservices:
Microservice develops a set of small services. Each service has its own process. It can be also thought of as a form of service-oriented architecture. Microservice is currently in demand among all the Java developers. As if you will not learn microservices then you’ll lag behind your competitors.
There are various microservices frameworks that you can use for Java development. Such as Spring Boot, Jersey, Swagger and so on. Instead of this, You can also consider Ninja Web, Play Framework, Restlet, Restx and Spark Framework. In microservice the use of Spring Boot and Spring Cloud makes the development process simple and easy for Java developers.
10. Test Driven Development (TDD):
TDD (Test Driven Development) is the important skill every Java developer should learn. You need to dive deep in the TDD skill and understand the concept of TDD, it can be new to most Java specialists. Test Driven Development might improve your coding quality and help you in offering better finished products.
There are few benefits of learning TDD skills such as by learning TDD you can clear the bug as early as possible, TDD gives the best design and more extensible code. It is the skill that benefits your teamwork. In absence of any team member you can easily pick their work and start coding.
Wrapping Up:
It is essential to update yourself with the programming language that you are learning. Normally in every six months, there is a new update in Java and it is the biggest challenge to keep up with the changes.
Most experienced Java Developers have crossed at least 10 new versions of Java programming language. To become a Java specialist developer you need to learn 8+ skills.
