Easy question about connecting characters

[Ismael Upright]

Just what characters are called connecting characters? Every time I want to find the list of them I get only this: "_"

There are the characters that may start the identifier.

I'll try to explain:

Legal identifiers must start with a letter, a currency character or a connecting character such as the underscore (_).

My question is: are there another connecting characters than (_) ?

Full list of connecting character please?

[Jari Timonen]

That is a very good question. All i could find: connecting character, such as "_".

Somebody?

The connecting characters are those that belong to the Unicode category 'Pc' (Punctuation, connector). Here's a complete list for the current version of the Unicode spec:

There's a little more information about this topic in this thread.

There might be other connecting characters, but underscore (_) is the only one on a standard English keyboard. We can assume that the exam does not test on non-standard keyboards

Uma Bandaru, welcome to JavaRanch.

Did you note that the question you answered is about 2 years old? The person who asked the question is most likely not waiting for an answer anymore - please don't wake the zombies.

Section 3.8 of the Java Language Specification explains exactly what characters are and are not allowed for identifiers (names for classes, interfaces, enums, variables, methods, etc.).

Thanks for the info. The answer is not necessarily for the person who posted it. I was just trying to close the open discussion in case there is anyone still wondering. Well, I will be content now thinking that people in 2009 have mastered connecting characters.
