public static String arrayToString(final Object obj){
    if (obj == null) {
        return "";
    }
    else {
        Object array = null;
        if (obj instanceof Collection) {
            array = ((Collection) obj).toArray();
        }
        else if (obj.getClass().isArray()) {
            array = obj;
        }
        else {
            return notNull(obj);
        }
        int length = Array.getLength(array);
        int lastItem = length - 1;
        StringBuffer sb = new StringBuffer("[");
        for (int i = 0; i < length; i++) {
            sb.append(arrayToString(Array.get(array, i)));
            if (i < lastItem) {
                sb.append(", ");
            }
        }
        sb.append(']');
        return sb.toString();
    }
}
