Java Parse class name from sources

Question

I'm trying to parse the class name:

public class Script {


}

And I'm using regex at the moment but it doesn't work as good as I though, my regex

class\s+(.*?)\W

But when things like extends and implemented comes in it's breaking itself.

I'm making a script that downloads sources from pastebin and auto saves it.

Thanks.

Try to be stricter about the characters a name can contain. For example it can't contain any whitespace characters. — Joachim Sauer

This could do the trick :

serach for all characters excepts spaces or bracket class\s+([^\s{]+)\s*

The Problem with class\s+([^\s]+)\s is, that it would return 'ClassName{' as result, if a space is missing between the ClassName and '{' - example: 'class ClassName{'

you are right, i updated the regexp to stop if there is a space or a "{"

Try to use class\s+(\w*)\s*

This would also handle the case of class Classname{ whitout a space after the Classname
