Java Developer Roadmap

Core Java to Spring Boot — the most placement-friendly language in India.

Java remains the most placement-friendly language in India — service companies hire heavily for it, and Spring Boot backend roles pay well. This roadmap takes you from core Java to job-ready backend developer.

Core Java and OOP first, then collections and the JVM, then Spring Boot and databases. Combine with DSA (Java is a great DSA language) and you're set for both campus and off-campus placements.

4–6 months Beginner → Job-ready 9 core skills

Phase 1 · Core Java

Weeks 1–5

Java fundamentals

Syntax, data types, operators, control flow, arrays and methods.

DSA in Java

Master interview patterns — Java is excellent for DSA rounds.

Placement prep

Aptitude, resume, and Java interview questions (collections, OOP, multithreading).

Projects to build

Recruiters probe projects, they don't count them. Ship 2–3 of these, deploy them, and put them on GitHub with a clean README:

REST API with Spring Boot + PostgreSQL/MySQL
Full CRUD web app with authentication
A library / inventory / booking management system

Frequently asked questions

Is Java still worth learning in 2026?

Yes — Java has one of the largest job markets in India, especially for campus placements and enterprise backend roles. Spring Boot skills pay well.

Java or Python for placements?

Both are great. Java is dominant in service-company placements; Python is strong for startups, data and AI. Pick based on your target companies.
