A) Java identifiers cannot have the characters "!", "'" or "-" in them making answer C, D and E wrong. The word "class" is a reserved word in Java and cannot be used as an identifier. The identifier "i" is perfectly legal although it is not necessarily a good identifier since it is not descriptive of its use.
