When wca4z transforms a COBOL program, which Java structural element typically corresponds to the COBOL PROCEDURE DIVISION?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'A Java annotation class that marks the business rule at the class level'. wca4z maps COBOL PROCEDURE DIVISION sections and paragraphs to Java methods within a class, preserving the logical structure of the business logic while adopting Java naming and calling conventions. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
