Frequently asked questions

What does a Java developer do?

A Java developer builds backend services and enterprise applications in Java, often with the Spring framework. They build API endpoints and business logic, work with databases, handle errors and write tests. At the entry level they deliver assigned features and learn Spring and the Java ecosystem, which runs a large share of banking, enterprise and product systems in India.

Is Java still in demand in India?

Yes, strongly. Java runs a huge amount of enterprise, banking and product software in India, and Spring Boot is a standard for backend services. Demand for Java developers stays high across service companies, product firms and global capability centres, so learning core Java, Spring and databases well opens many entry and senior roles.

What should a fresher learn to become a Java developer?

Learn core Java and object oriented programming first, then Spring Boot for building web services, plus SQL and a database. Add REST API design, JUnit testing, Maven and Git. Build a couple of projects such as a REST API with a database. Strong fundamentals and clear code matter more than the number of frameworks you list.
