Matching arabic text with regex

Question

I'm trying to match only arabic text using regex but I'm getting an exception. Here's my code:

txt.matches("\\P{Arabic}+")

Here's the exception:

Exception in thread "main" java.util.regex.PatternSyntaxException: Unknown character property name {Arabic} near index 9 \P{Arabic}+

Use this character block

\p{InArabic}+

In java Unicode scripts, blocks, categories and binary properties are written with the \p and \P(negated effect)

Scripts are specified either with the prefix Is or by using the script keyword(supported scripts)
Blocks are specified with the prefix In or by using the keyword block(supported blocks)
Categories may be specified with the optional prefix Is or using keyword general_category or gc(supported categories)
Binary properties are specified with the prefix Is (supported properties)

OK may bad, I was using P instead of p, out of negligence. – Behnam Oct 20 '14 at 09:15
