Java is the most popular and evergreen programming language in the world of IT Industry. This is the reason why Java Developers are in a steady race of upgrading their skills. This article exclusively targets on the crucial Java Developer Skills required in 2019.


Who is a Java Developer?


Java Developer is a Computer Software Developer/Programmer who integrates Java Programming Language into the development of Computer Applications, Web Development and other sorts of requirements needed at both Client and Server end.


How to become a Java Developer

There are three basic stages on the way in becoming a Java Developer.

Earning a College Degree

The first stage requires you to complete a qualification in Computer Science with a focus on software development. This could be a Degree in Information Technology or Bachelor of Engineering in  Computer Science.

Getting Java Certification

The second stage requires you to complete an online or offline course specializing in Core and Advanced Java. Trying out online examples is a good way to develop your specialization in Java.

Getting Experienced

The third stage needs you to look for a placement in an internship program while studying. This will provide you with relevant experience as well as guidance and mentorship from experienced Software Developers.

Let us understand the skills required by a Java Developer in a detailed way in the next segment.


Skills of a Java Developer

The Skills required for Java Developers can be categorized as follows:

  1. Java Developer Skills (Technical)
  2. Java Developer Skills (Soft Skills)


Java Developer Skills (Technical)

Core Java

Let us understand the most basic and essential skills required to become a Java Developer. Core Java Skills are building blocks of every successful Java Developer. The crucial Core Java skills that most recruiters are looking for are,

  • Object-Oriented Programming skills

Object-Oriented Programing approach introduces class and object style of coding that deals with the concepts of Inheritance, Encapsulation, Abstraction, Polymorphism. The motto of OOP is to bind the data and the functions together, so as to improve code stability and safety.

  • Design Patterns in Java

Design patterns in Java are standard solutions followed to solve routine problems faced in software designing life cycle. Every Design Pattern acts as a blueprint that allows customization to solve any given design problem in any code during the development of software modules.




  • Abstract Classes in Java

Abstract Classes in Java help the developers to achieve abstraction. Abstraction in object-oriented programming reduces code complexity by showing only the relevant details of the objects used in the program and enhances code readability. We need Abstract classes in java for the following reasons.

  • Interface in Java

Java Interface is an advanced level of achieving abstraction in the Java Programming Language. The interface in Java enables a better and efficient way of achieving abstraction in Java

  • Serialization in java

Serialization in Java is a concept that deals with the conversion of objects into a byte stream to transport the java objects from one Java Virtual Machine to the other and recreate them to the original form. Serialization enables developers to meet various factors in real-time programming.





Java Build Tools

Depending on the tasks assigned, Developers need to use a specific tool for a particular task. For a Java Developer understanding the terminology of Build tools in Java comes handy as Java Build tools are the programs that automate the creation of executable applications from source code. Build tools that one must know are Maven and Gradle


    Web Technologies

    Web technology provides a simplified, fast way to create dynamic web content. Having a better grip on Web technology is important as it helps to understand the technique of establishing communication between multiple computer systems via markup languages. It gives a way to interact with the host for information, like websites. It involves the use of  HTML, JQuery, and CSS.


      Java Web Frameworks

      To build a Mobile application with best features and limited code, Java web frameworks are the best in class solutions. They support the development of web applications including web services, web resources, and web APIs in a standard way to build and deploy web applications on the World Wide Web. Some of the best frameworks are Spring MVC and Play.


        Java Application Containers

        Java Application container is an application program in which the software’s building block known as a component is run. Application containers are designed to provide multiple functionalities such as to provide user authentication, logging or establishing a connection with the database. Top-notch Java Application Containers are JBoss and Jetty.


          Java Testing Tools

          Java Testing Tools allow you to test your JSP pages and Web Application with an interface where you do not have to actually launch your application onto a web browser. They support multiple test activities from planning, requirements, creating a build, test execution, defect logging and test analysis. Testing tools are Selenium and TestNG.



              Big Data has become a trillion-dollar industry and handling such a huge amount of data has become close to impossible by traditional data processing software. Learning Big data technologies helps developers to analyze and extract information from complex data sets. Some of the powerful Big Data technologies are Hadoop and Spark


                Java EE Components

                Java EE Components enable Developers to write server-side applications. One of the most common challenges that the enterprise developers face is how to handle requests coming in from web-based clients. To ease this challenge, Java EE provides the Servlet and JavaServer Pages APIs, that enable methods for logging activities using cookies on a user’s browser and simplify these kinds of issues and provide the best solution. Some major Java EE components are Servlets, Java Beans and Java Server Pages.


                  Code Version Control


                  GitHub Version control allows developers to keep track of their work and helps to easily explore the changes they made in data, coding scripts, comments, etc so, that it is much smoother and easier to implement


                  Java Developer Skills (Softskills)

                  Soft skills are people skills, communication skills, character and social intelligence among others, that enable people to navigate their environment, work well with others, perform well, and achieve. The soft skills for Java Developers are:

                  • Good Communication Skill


                  Good Communication Skills include active listening where you pay close attention to the person who is speaking to you and try adapting your communication style to your audience and convey your message in a better manner.

                  • Open to Learning

                  Knowledge is never-ending. Successful Java Developers should be always open to learning new upgrades in the technology and keep themselves updated

                  • Team Work


                  Teamwork is the collaborative effort of a team to achieve a common goal and to complete a task in the most efficient and effective way.

                  • Work Ethics

                  Work ethic is a belief that hard work and dedication have a moral benefit and an inherent ability, virtue or value to strengthen character and individual abilities

                  • Interpersonal Skills


                  Interpersonal skills are the qualities and behaviour a person uses to interact with others properly. The better the interpersonal Skills, the better the growth in one’s career.
