Futuristic and highest paid Java developer Skills
I think the subtitle says it all. Following are the special technical skills that will continue to play a major role in the future of a java developer.
At the same time learning these skills will fetch you tech jobs with the highest salaries.
But, before getting to know about the advanced Java developer skills. First, let us know the basic and essential skills required to become a java developer.
Core Java skills:
The crucial core Java skills that most of the recruiters are looking for are,
Object-Oriented Programming skills (OOP)
The objective of possessing this skill is to bind the data and the functions together, so as to improve code stability and safety.
Design Patterns in Java
Knowing the Design patterns in java, allows you to customize and solve any given design problem in any code during the development of software modules.
Abstract Classes in Java
If you are familiar with Abstract classes in Java, it helps you to achieve the abstraction. It means, it helps the developer to reduce the code complexity and enhance code readability.
Advanced Java developer Skills that recruiters mostly prefer to pay high
Java Build Tools :
Being an advanced Java developer, you must complete the assigned task in a given time. At that period, you must be popular to use a specific tool to complete a particular task.
Build tools that one must know are Maven and Gradle, Ant. These tools are used for managing project dependencies, configurations and build configuration and documentation.
Java Web Frameworks :
As a notable Java developer, you will come across building some compelling mobile application with best features and limited code. Then you must be familiar to use Java web frameworks, which is the best in class solutions.
Some of the best Java Web frameworks that you should have hands on experience are Java Server Faces (JSF), Spring MVC, Vaadin/GWT, Wicket, Play.
The above mentioned Java Web Frameworks support the development of web applications. This includes web services, web resources, and web APIs in a standard way to build and deploy web applications on the World Wide Web.
Java EE components :
Today, one of the most common challenges that every enterprise developer faces is how to handle requests coming in from web-based clients. Thus, having Knowledge on Java EE components will ease this challenge.
Some major Java EE components are Java Server Pages (JSP), Servlets, Enterprise Java Beans (EJB), JAX-RS, JAX-WS, Java Message Service (JMS).
This Provide Developers to write server-side applications and enables methods for logging activities using cookies on a user’s browser and simplify these kinds of issues and provide the best solution.
Code Version Control :
As a skilled Java developer, you probably come to know that an older version 10 lines of code can be simplified by just 1 or 2 lines using latest classes/methods.
For this, the mostly used version control is Git. This allows developers to keep track of their work and helps in exploring new changes made in data, coding scripts, comments, etc. This is easier to use and implement.
Object Relational Mapping (ORM) :
As an advanced Java developer, you must have Object Relational Mapping (ORM) skills. As relational databases are represented in a tabular format using rows and columns. So, when it comes to saving an object in a database, there exist some obvious mismatch. So to handle this mismatch, there exists ORM.
ORM can be simply defined as a framework, which is used to map an object to a relational database.
Thus, to handle mismatches, there are many available ORM tools like Hibernate, Java Persistence API (JPA), EclipseLink, OpenJPA. This is used for persisting data in relational databases.
To be pointed, in these days, Hibernate is the most widely used ORM framework. as it is a very stable framework and possess many extra capabilities than other ORM tools available.
Java Application Containers :
One of the great java developers, you must be sure known about Java Application container. It is an application program in which the software’s building block known as a component is run.
The most commonly used top-notch application containers are Tomcat, JBoss/Wildfly, Undertow, Jetty, WebLogic, WebSphere.
These Application containers are designed in a way to provide multiple functionalities. This includes user authentication, logging or establishing a connection with the database.
Java Testing tools :
As a Professional Java developer, you work on very different areas, starting from writing core Java code to creating JSP pages, writing REST APIs, and sometimes even creating Groovy scripts for build automation.
At that point of time, please ensure you are familiar with a wide range of tools for unit testing, automation testing, performance testing and integration testing.
Some popular testing tools are JUnit, TestNG, Spock, Mockito, Cucumber, Selenium. These tools allow you to test your JSP pages and Web Application with an interface where you are not supposed to actually launch your application onto a web browser.
These Java testing tools also support multiple test activities starting from planning, requirements, creating a build, test execution, defect logging and test analysis.
Inversion of Control (IoC) frameworks :
This Java platform is one of the most important skills required for every java developer.
Some popularly used Ioc frameworks include Spring Framework, Guice, CDI.
As it enables every developer to build applications from plain old Java objects (POJOs) and also useful for Java SE programming model.
According to the report, stating that in recent days, most of the Java Development Companies use Spring framework such as Spring Boot, Spring MVC, and Spring Cloud for developing a web application, microservices, and REST APIs.
Java Virtual Machine (JVM) and Memory Management :
These two skills are the most crucial and trickier subject that every Java developer needs to be skilled in.
Even if you are a beginner in Java Application development, you must possess some working Knowledge in JVM. As, it is the significant element of JRE (Java Runtime Environment).
In case you are familiar with JVM, then you can understand Java in a better way. As it helps you to solve complex problems that occur in programming.
Thus to become a great Java Developer, learn how JVM works, JVM system threads, how JVM executes JAVA bytecode, and the order of execution.
To be pointed, to hone your Java skills in 2019, you must be aware of JVM stack restrictions and some common mistakes that most of the Java Developers make.

The above mentioned are the important terms of computer science. Once you build your skills in the foundation aspects of Java, then you can set your sights on emerging technologies and industry trends.
So, being an advanced Java developer, must should have an Artificial Intelligence skill. It is the study of how to train the computers so that computers can do things which at present humans can do better. On the other hand, Machine learning skills refers to systems that can learn from experience.
Some of the powerful Big Data technologies are Hadoop and Spark
Learning Big data technologies helps Java developers to analyze and extract information from complex data sets.
Need for Java Developer Soft Skills
As a Java developer, you won’t work alone. As you are the key members of the development team, and you are supposed to work with various staff both inside and outside the IT realm.
Therefore, it is important to demonstrate some soft skills include.,
