Here’s How To Become A Java Developer in 2023 – Salary, Resume, and Skills You Need

Java Developer

Java is the mother tongue of approximately 9 million developers around the globe. Developed first in 1995 by Sun Microsystems, Java has evolved to become one of the most popular languages to be used in the software industry. It is fast, secure, and reliable, therefore, used to make applications ranging from software design and gaming technology to web and mobile applications.

Speaking from programming notions, Java is concurrent, class-based, object-oriented, and based on bedrock languages like C and C++. This makes java extremely versatile, coder friendly, and skill-set in demand. With most large-scale companies having their software systems and backend services implemented in java, a java developer is one of the most sought jobs of 2021.

This article will give you a holistic overview of the job profile and help you get started with your journey to become the best in the field.

What is Java Developer?

Jobs Based on Skills

As a Java Developer, you will have opportunities to work with more than 64,000 MNCs who have a massive percentage of their products either made or supported by java coded software.

Though there has been a rise in the popularity of coding languages like python and go, java being robust and efficient, will not leave its mark anytime soon. And hence the opportunities to work as a java developer stay strong.

To give you a clear picture, we have evaluated numerous job descriptions and present you with a concise description of what to expect with the job in this section.

Two broad domains that java developers work in are: Software/Back-End Development and Mobile App Development

Software and Back-End Development

As software and backend developers, java developers contribute and work hands-on in all spheres of a project right from conceptualization, requirement gathering, fit-gap analysis, design, development to production implementation and support.

Here, the developer goes through the entire software development life cycle which includes:

  • Design, implement, maintain and improve java application phases
  • To take part in software and architectural development activities
  • Conduct software analysis, programming, testing, and debugging
  • Identify production and non-production issues
  • Transform requirements into specifications
  • Develop, test, implement and maintain software applications
  • Recommend changes to improve established java application processes
  • Develop system designs for application development
  • Develop application codebase for java programs

To comply with these roles and responsibilities, one must develop the following java developer skills:

  • Android Development – Java/Kotlin
  • Git and GitHub
  • API creation
  • SQL and NoSQL Databases
  • Data Structure and Algorithms

Tips for Acing Java Developer Roles

  • Master Basics

You should know and understand basic concepts like loops, arrays, operators, and other basic functionality libraries. Also, focus on implementing OOPs concepts.

  • Keep Practicing

After getting a hang of the basics, you can try learning Java EE (Enterprise Edition) aka advanced java. This includes technologies like Servlet, WebSocket, Java Server Faces, etc. for web specifications.

  • Make Projects

This is something that you can add to your resume to showcase your problem-solving and practical coding skills.

  • Learn Specific Libraries/Tools

Most Java Development Companies use Spring frameworks such as Spring Boot, Spring MVC, and Spring Cloud for developing web applications. Hibernate is also a very popular framework for mapping a domain object-oriented model to a relational database and the Hibernate Query Language.

Java Developer Salary

The questions are a little bit easier and more practical than what is asked for SDE roles.

Another essential thing about Java interviews is questions based upon Java programming language and JDK API. Since Java is also an Object-oriented programming language, you will find lots of OOP questions there.

A list of common interview topics is as follows:

  • Java Fundamentals
  • Object-Oriented Concepts
  • Data Structure and Algorithms
  • Multithreading, concurrency, and thread basics
  • Date type conversion and fundamentals
  • Garbage Collection
  • Java Collections Framework
  • Array
  • String

  • Abstract class and interface
  • Generics and Enum
  • Java IO and NIO
  • Common Networking protocols
  • Regular expressions
  • JVM internals
  • Java Best Practices
  • JDBC
  • Date, Time, and Calendar
  • XML Processing in Java
  • JUnit

For skill-specific roles, one shall prepare and have projects using those specific skills. For Example Java Web Service, REST API, SOAP API, JSON, XML, and other relevant topics.
