The syntactic grammar for Java is given in Chapters 4, 6-10, 14, and 15. This grammar has Java tokens defined by the lexical grammar as its terminal symbols. It defines a set of productions, starting from the goal symbol CompilationUnit (§7.3), that describe how sequences of tokens can form syntactically correct Java programs.
A LALR(1) version of the syntactic grammar is presented in Chapter 19. The grammar in the body of this specification is very similar to the LALR(1) grammar but more readable.
