代码如下:
public static Integer haveChineseNum(String value) { int count = 0; String regEx = "[\u4e00-\u9fa5]"; String str = value; Pattern p = Pattern.compile(regEx); Matcher m = p.matcher(str); while (m.find()) { for (int i = 0; i <= m.groupCount(); i++) { count = count + 1; } } System.out.println("值="+value); System.out.println("共有 " + count + "个 "); return count; }
