Enterprise-grade programming language
Java is one of the most popular and widely-used programming languages, powering enterprise applications, Android apps, big data tools, and web services. This roadmap covers Java fundamentals, object-oriented programming, collections framework, multithreading, Spring Boot for backend development, and the broader Java ecosystem. Java's 'write once, run anywhere' philosophy, strong typing, and extensive libraries make it ideal for large-scale applications. It's used by major companies like Google, Amazon, and Netflix. Understanding Java opens doors to backend development, Android development, big data engineering, and enterprise software development.
