Java正則表達式識別中文

1. public static void regxChinese()
2. {
3. String source = "桑德斯ABdD3ddd5222字符串轉換健康康可能34f豐富4f成小寫dx5kljfdsljDSknf943立即地方立即的ddd頂頂頂3";
4. String reg_charset = "([a-z]*)([A-Z]*)([0-9]*)([\u4E00-\u9FA5]*)";
5. Pattern p = Pattern.compile(reg_charset);
6. Matcher m = p.matcher(source);
7. String tag = "demo";
8. while (m.find())
9. {
10. Log.d(tag,"0~~~~~~~~~~~~~~~ " + m.group(0));
11. Log.d(tag,"1~~~ " + m.group(1));
12. Log.d(tag,"2~~~ " + m.group(2));
13. Log.d(tag,"3~~~ " + m.group(3));
14. Log.d(tag,"4~~~ " + m.group(4));
15. }
16. }

以上方法也實現了將大寫英文，小寫英文，數字，中文的互相分離。
