如何让判定字符串中的中文

方法一：

/**
 * @param originStr String contains Chinese character.
 * @return the number of Chinese character
 */
	public static int countChineseCharacter(String originStr) {
		int count = 0;
		String temp = null;
		for (int i = 0; i < originStr.length(); i++) {
			temp = String.valueOf(originStr.charAt(i));
			if (temp.getBytes().length == 2)
				count++;
		}
		return count;
	}

方法二：

	/**
	 * @param originalStr String contains Chinese character.
	 * @return the number of Chinese character
	 */
	public static int countChinese(String originalStr){
		int count = 0;
		Pattern pattern = Pattern.compile("[\u4e00-\u9fa5]");
		Matcher matcher = pattern.matcher(originalStr);
		while(matcher.find())
			count++;
		return count;
	}
