The list of methods to do ArrayList Join are organized into topic(s).

Method

Stringjoin(ArrayList list, String delimeter)
Folds the list into a string, putting the delimeter in between each element of the collection. 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < list.size() - 1; i++) {
    sb.append(list.get(i).toString()).append(delimeter);
return sb.append(list.get(list.size() - 1).toString()).toString();
Stringjoin(ArrayList arr, String separator)
join 
if (separator == null) {
    separator = ",";
StringBuilder sb = new StringBuilder();
for (int i = 0; i < arr.size(); i++) {
    if (i > 0) {
        sb.append(separator);
    sb.append(arr.get(i).toString());
return sb.toString();
StringJoin(ArrayList coll, String delimiter)
Join 
if (coll.isEmpty())
    return "";
StringBuilder sb = new StringBuilder();
for (String x : coll)
    sb.append(x + delimiter);
sb.delete(sb.length() - delimiter.length(), sb.length());
return sb.toString();
Stringjoin(ArrayList list)
join 
if ((list == null) || (list.size() == 0))
    return "";
StringBuilder sb = new StringBuilder();
boolean first = true;
for (String item : list) {
    if (first)
        first = false;
    else
...
Stringjoin(ArrayList list, String delimiter)
join 
StringBuilder stringBuilder = new StringBuilder();
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
    stringBuilder.append(iterator.next());
    if (!iterator.hasNext())
        break;
    stringBuilder.append(delimiter);
return stringBuilder.toString();
StringJoin(ArrayList list, String delimiter)
This method converts a list of String objects to a single String representation and inserts a delimiter between each object. 
if (list.isEmpty())
    return "";
StringBuilder sb = new StringBuilder();
for (String x : list)
    sb.append(x + delimiter);
sb.delete(sb.length() - delimiter.length(), sb.length());
return sb.toString();
Stringjoin(ArrayList list, String joinChar)
join 
StringBuilder sb = new StringBuilder();
int i = 0;
int size = list.size();
for (String part : list) {
    i++;
    sb.append(part);
    if (i != size) {
        sb.append(joinChar);
...
Stringjoin(ArrayList nameList, String delimiter)
Join.
String string;
StringBuilder builder;
if (nameList == null || nameList.isEmpty())
    return "";
Iterator<String> iter = nameList.iterator();
string = iter.next();
if (string.equals("")) {
    builder = new StringBuilder(iter.next());
...
Stringjoin(ArrayList s, String delimiter)
join 
StringBuilder buffer = new StringBuilder();
for (int i = 0; i < s.size(); i++) {
    if (i != 0)
        buffer.append(delimiter);
    buffer.append(s.get(i));
return buffer.toString();
Stringjoin(ArrayList strings, String separator)
Join an array 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < strings.size(); i++) {
    if (i != 0)
        sb.append(separator);
    sb.append(strings.get(i));
return sb.toString();
