Java judgment character for Chinese instance Code (super Works) _java

In the project will often encounter a project needs to determine the characters are some of the problems of Chinese, so the collection of the text of the judgement of the Code fragment, hereby share for your reference.

The code is posted directly, with detailed comments in it.

If only to determine whether it is Chinese, do not need to judge Chinese punctuation, it is recommended to use the regular to match, may be more efficient point.

The above code content to introduce the Java Judgment characters for Chinese instance Code (super Works), I hope to help you.
