Java Zero to Hero: Master Real Projects & Crack Interviews

This course contains the use of artificial intelligence.51 animated lessons · 6 hours 6 minutes · zero experience needed. Go from your first line of Java to five real projects, the interview classics, and senior-level topics — every concept animated so you can see how it works.Now expanded: Spring Boot projects, Docker, microservices, JVM tuning, system design cases, and a full second DSA pack — with quizzes, coding exercises, and exercise PDFs with solutions throughout.NEW — Project 5: TicketKiosk, a real Spring Boot web application. Not a toy CRUD: an event seat-booking app with holds that expire, JWT-secured endpoints, and the double-booking race solved with optimistic locking — proven by a 100-thread storm test (one seat, exactly one winner).Every API method, hands-on: GET · POST · PUT · PATCH · DELETE — each used for its real job, including the PUT-vs-PATCH difference shown side by side.Postman collection included: import the ready-made TicketKiosk collection (environment + JWT auth flow saved) and test every endpoint like a professional — the same workflow real Spring Boot teams use daily.Welcome to NammaCoder Academy's complete Java programming course — a practical, project-driven path from absolute beginner to interview-ready Java developer.This course takes you from zero programming experience to a confident Java developer through hands-on coding from the very first lecture. You will learn Java fundamentals including variables, data types, operators, and control flow, then progress to object-oriented programming with classes, objects, inheritance, polymorphism, encapsulation, and abstraction.You will master essential Java libraries and modern features: the Collections Framework (List, Set, Map), exception handling, generics, lambda expressions, and the Streams API for clean, efficient data processing. Every concept is reinforced with coding exercises and practice problems so you can apply what you learn immediately.What sets this course apart is its focus on real projects. You will build complete, working Java applications step by step, applying everything you learn to realistic scenarios that mirror actual developer work. You will also find dedicated interview preparation: commonly asked Java interview questions, coding challenges, and clear explanations of the concepts interviewers test most.By the end of this course, you will be able to write clean, well-structured Java programs, apply object-oriented design principles, work with collections and streams confidently, handle exceptions and debug effectively, and approach technical interviews with solid preparation.NammaCoder Academy is committed to practical, beginner-friendly programming education.
