java判断数组中是否包含某元素

    private static boolean isContainKey(String[] keys, String targetValue)
    {
        if (keys == null || keys.length == 0)
        {
            return false;
        }

        for (String str : keys)
        {
            if (StringUtils.equals(str, targetValue))
            {
                return true;
            }
        }

        return false;
    }

	Arrays.asList(arr).contains(targetValue);
