Java is one of the most practiced technologies. A Java developer is a part of the software development team who builds, design, and manage applications using the versatile, cross-platform programming language Java. They run Java code and are part of the whole process of developing an application. From programming to solving errors, a Java developer will ensure the effective and efficient development of an application and deployment on a server.
What is Java Used for?
Web-Based Applications
Java provides easy coding and high security, enabling the creation of many apps for health, education, and insurance. It is compatible with such tools as Servlets, Hibernate, Spring, Struts, Apache HTTP web server, Apache Tomcat, Thymeleaf, and many others. Using these technologies, you can build any web-based application. E-commerce web applications also use this language with the help of open-source eCommerce platforms, such as Broadleaf. Gmail, Google Sheets, Google Slides, and many more are examples of web-based applications which employ this language.
Building Android Applications
When developing mobile apps, your choice of application target platform will determine the technology stack. For example, apps for the iOS platform are developed with Objective-C and Swift, but the iOS platform is used only on 17% of devices other 83% use Android. Therefore, it is the leading computer language for Android apps. Its main competitor for application development is Kotlin, but it is compiled to the byte code JVM executes, and we can say it is just a “cleaner” version of Java. And by the way, Java is compatible with the most popular tool for Android apps - Android Studio.
Embedded Systems
Embedded systems are at the heart of many products, machines, and intelligent operations, such as machine learning and artificial intelligence applications. We can divide embedded systems into four types:
- Real-time
- Stand-alone
- Networked
- Mobile
Finding a product missing this technology in the modern world is almost impossible. Even refrigerators and microwave ovens are examples of stand-alone embedded systems. And almost all these systems use Java.

Big Data Technologies
Big Data has been among the top discussed topics for the last few years. Most often, developers use Scala, Python, and Java for Big Data. In addition, such technologies as Apache Hadoop, Apache Mahout, and Apache Storm use Java in one way or another. So it is a good choice for Big Data too.
Cloud-based Applications
Java is a good fit for utility computing too. A cloud-based application is computing based on the internet. So every time you check your email, use Google Drive, or search for something on the internet, you benefit from a few cloud capabilities. There are 5 essential characteristics of the cloud:
- On-demand capability
- Broad network access
- Resource pooling
- Rapid elasticity
- Measured service
This language helps to develop applications in three cloud delivery models: Infrastructure as Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). In addition, many cloud-building instruments for Java contribute to designing and configuring servers, such as AWS SDK for Java, Oracle Cloud service, Google App Engine, etc. That's why many companies headhunt Java developers to help actualize the transition to a cloud for business continuity, increased scalability, and cost-efficiency.
Gaming Applications
The mobile gaming industry is becoming larger yearly, and we can predict it will only grow. 83% of all mobile devices use Android. And since Java supports Dalvik Virtual Machine, which runs on the Android platform, and jMonkeyEngine (a 3D engine capable of creating 3D games), it is the primary language for Android games.
Software Tools
Is Java used anymore in software solutions? A software tool is one of the most important things for a developer because it helps build, debug, and support programs. Developers commonly use Eclipse, NetBeans IDE, and IntelliJ IDEA tools, all of which support Java. Even more, all of them were written in Java.

Java Developers Roles and Responsibilities
Java is a dynamic language (a language that allows run-time modification, i.e., to change the structure even while the code is running, to increase efficiency and productivity for general-purpose programming.). A Java developer's role and responsibility for a programming language as robust as Java also intensify.
In addition, a Java developer is responsible for the holistic development of an application, making him/her significant in the software development team. The core roles and responsibilities of a Java developer are:
- Plan, design, execute, and manage the Java application process.
- Write codes for Java-based applications.
- Stay up to date with the Java updations.
- Test (development testing) and run codes for the application software
- Analyze and debugs the software application.
- Work proficiently with database management systems.
- Integrate code programming and development testing for frontend and backend applications.
- Participate in the complete analysis process for software applications.
- Assist in maintaining the applications

Experience
A Java developer is not just a programmer who writes codes to run a program. He/she works towards the full development period – from design to deployment. To be efficient in all parts of the application development process, the developer has to have a good amount of experience.
So, when deciding on the average salary of a java developer in India, experience plays a key role as a deciding factor. The average salary of a Java developer for a fresher is ₹293,272 per annum, whereas for an experienced Java developer, the average pay is ₹1,396,371 per annum.
Location
Bangalore is called India’s Silicon Valley, and Pune is famous for its job opportunities, but no one has ever heard of Rajasthan that much for great job openings. And this highlights our second significant salary deciding factor, location. Every location has a different set of opportunities and demands. In India, most metropolitan cities have better job opportunities than small towns. Therefore, location plays a lot more in deciding your pay structure than you think.
Employer
Starting your career at a startup or a big firm might not only have different learning opportunities but pay scale as well. Bigger companies have larger responsibilities and stable financial standing to give their employees the average base pay in comparison to the startups that are on the brim of growing big.

While Java is the most popular programming language due to its versatility in designing customized applications that are light and fast and serve various purposes, it is still a challenging coding language to learn. There is a lot of competition for Java developer roles.
To make it easier to become a Java developer, it is useful to take a focused approach. This starts by mastering Core Java, which will allow a person to understand basic concepts like loops, arrays, and operators.
A person needs to keep practicing writing the syntax without any basic errors. As a person continues practicing and has mastered Core Java, they should move on to Java EE, which, once they know well enough, they should combine with Front End technologies such as HTML, CSS, and Javascript and try to make mini-projects.
Finally, when a person has mastered both Java SE and Java EE, they should focus on Java Frameworks. Make projects, especially on Hibernate and Spring Frameworks that can be shared with companies during an interview, and a person will have a good chance of getting selected for the role of a Java developer in any company.
