Most Java tutorials teach you what to write. This series is different — it explores the language from the perspective of how the JVM actually processes your code, guided by the original documentation that most developers never open.
In this first chapter, you'll explore:
- How the JLS formally defines Java through context-free grammars
- The difference between lexical grammar and syntactic grammar
- How raw text is transformed into tokens before compilation even begins
- Why understanding lexical analysis changes the way you read (and debug) code
This isn't another tutorial sequence — it's a deep dive into the arcane foundations of Java SE 25, built directly on the Java Language Specification.
