java識別字串中的漢字

直接上代碼

import java.io.UnsupportedEncodingException;import java.net.URLEncoder;import java.util.regex.Matcher;import java.util.regex.Pattern;public class Stringtest {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubString s = "abcd";String s1 = "我愛你..shenme話的故事";String s2 = null;try {s2 = URLEncoder.encode(s1, "utf-8");} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();}for(int i =0;i<s1.length();i++){System.out.println(isChinese(s1.charAt(i)));}}public static boolean isChinese(char c) {String regEx = "[\u4e00-\u9fa5]";Pattern p = Pattern.compile(regEx);Matcher m = p.matcher(c + "");if (m.find())return true;return false;}}

用到Regex ”[\u4e00-\u9fa5]“ 。
