Which statement about methods inside a class body is correct?

• A. They may be separated by commas.
• B. Methods should never be comma-separated if inside of a class body.
• C. They must be separated by semicolons.
• D. They should be on separate lines.

Answer: (B)

Inside a class body, methods are defined as separate class elements using the syntax name() { ... } with no separators between them. There is no comma or semicolon required or allowed between method definitions; the class body simply lists them one after another. That makes the idea of never separating methods with a comma the best rule, since commas belong to separating items in arrays or object literals, not in class bodies. Semicolons also aren’t used to separate methods—each method ends with its own closing brace. You’ll often see each method on its own line for readability, but the essential point is that comma separation isn’t used inside a class body.
