Multiple choiceMediumchapter-16-curatedpremiumjava-annotationsannotation-processors
Answer and explanation
Correct answer
D. It reads the AST to generate additional source files.
Why
Annotation processors read the Abstract Syntax Tree (AST) to analyze code and can generate additional source files based on this analysis. They do not directly modify the AST or compile it into bytecode; their role is to augment the code with generated elements such as additional classes or methods.
