String output = null;
try {
    for (int i = 0; i < list.size(); i++) {
        if (i == 0)
            output = list.get(i).toString();

if (data.size() == 0)
    return "[]";
String result = "[";
for (Object v : data) {
    result += v.toString() + ",";
return result.substring(0, result.length() - 1) + "]";
StringconvertListToString(List list, char delimiter, int estimatedLength)
Converts a list to a string 
StringBuilder builder = new StringBuilder(estimatedLength);
for (Object value : list) {
    if (builder.length() > 0) {
        builder.append(delimiter).append(" ");
