Does the Java compiler execute comments?

Does the Java compiler execute comments?

• A. No, the compiler ignores characters inside comments
• B. Yes, they are executed at runtime
• C. They are compiled into bytecode
• D. They become part of the method signature

Answer: (A)

Comments are for humans. During compilation, the Java compiler strips out all comments in the source, so there is no executable code or bytecode corresponding to them. They don’t affect runtime behavior, and they don’t become part of the class’s bytecode or the method’s signature. Doc comments may be used by external tools like javadoc to generate documentation, but they are not part of the compiled code.
