Java uses regular expressions (regex) to match Chinese instance code

Only Chinese can be entered

PS: let's take a look at the regular expressions to match Chinese in Java. There are two ways to write them: one is to use Unicode Chinese code; Second, use Chinese characters directly;

Example:

(1) String STR = "clear";

(2) String STR = "clear";

explain:

(1) At present, most of the Chinese characters on the Internet are \ u4e00 - \ u9fa5. This range is only the range of "unified ideograph of China, Japan and South Korea", but it is not all. If you want to include them all, you need their extension sets, radicals, pictographs, inter note letters, etc.; specifically, you can view the simplified Chinese codes in Unicode

(2) "[I -]"; is the Chinese corresponding to the found \ u4e00 - \ u9fa5. Specifically, query uniocde2 Chinese
