In Java : How to detect whether a character is chinese or not?

[Rama Vadakattu]

In java how to detect whether a particular character is chinese character or not?

Can any one please guide me on how to solve the above problem?

[Campbell Ritchie]

Try the String.codePointAt() methods, then Character.isSupplemntaryCodePoint(). Go to the Unicode website and find what ranges of values represent Chinese characters. Compare the results of getting the code point and the Unicode charts.

And check the method names; I have probably spelt them wrongly.

Thanks for the guidance
to detect the chinese characters i used the following condition (detecting most of the chinese characters)..........

-----------------
if( (Character.UnicodeBlock.of(str[i]) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS) || )

-------------------
May be chinese,japnese characters fall into this UNICODE block
Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS (not very sure)

Yes, that's right. "CJK" means "Chinese, Japanese, Korean". And of course many Japanese kanji characters are identical in appearance to Chinese characters, so there's probably no point in trying to tell them apart.
