testing - Test if a string is a Java variable identifier: (a-z,A-Z,_,$) followed by (a-z,A-Z,0-9,_,$) -

i need determine if string variable identifier.

i.e. (a-z,a-z,,$) followed (a-z,a-z,0-9,,$)

i know can manually configured reg exp, there must more compact, built in function can use.

any solutions?

you can use methods character.isjavaidentifierstart() , character.isjavaidentifierpart() don't think solution more compact.
