如何在java中实现统计中文的字数

public class TongJiHanZi {   public static int count(String text) {     String Reg="^[\u4e00-\u9fa5]{1}$";//正则     int result=0;     for(int i=0;i<text.length();i++){     String b=Character.toString(text.charAt(i));     if(b.matches(Reg))result++;     }     return result;   }   public static void main(String[] args) {     String text = "汉字汉字仮名かなカナ 0189 azAZ ./ ";     System.out.println(count(text));   }}
