Comparing Java enum members: == or equals()?
...d that much extra safety.
However:
The fact that == never throws NPE in my mind is a disadvantage of ==. There should hardly ever be a need for enum types to be null, since any extra state that you may want to express via null can just be added to the enum as an additional instance. If it is unex...

...) seems to be missing an important subtlety about the role of white space. My proposition is that, checking eof() explicitly is not only not "always wrong" -- which seems to be an overriding opinion in this and similar SO threads --, but with proper handling of white-space, it provides for a cleaner...
