Java has long been a top-three general-purpose programming language on TIOBE and is a mainstay of enterprise backend development. This roadmap starts from core syntax, gradually deepens into object-oriented programming, exception handling, collection frameworks, concurrency and the memory model, functional programming and the Stream API, then advances to build tools, web frameworks, database access and unit testing, covering the complete body of knowledge from beginner to advanced Java developer. Follow the map step by step and build a solid Java foundation.
