final StringBuilder sb = new StringBuilder();
for (int value : array) {
    if (sb.length() > 0) {
        sb.append(c);
    sb.append(Integer.toString(value));
return sb.toString();
...
Stringjoin(List list, String separator)
join 
if (list == null || list.isEmpty())
    return null;
StringBuilder sBuilder = new StringBuilder();
for (Integer item : list) {
    if (item != null)
        sBuilder.append("," + item.toString());
sBuilder.deleteCharAt(0);
...
intjoin(List recycled)
join 
int ret = 0;
for (int i = 0; i < recycled.size(); i++) {
    ret += Math.pow(10, i) * recycled.get(recycled.size() - i - 1);
return ret;
Stringjoin(List list)
join 
StringBuilder sb = new StringBuilder();
for (Object x : list) {
    sb.append(x.toString());
return sb.toString();
Stringjoin(List list)
String join helper function 
return join("", list);
Stringjoin(List list, String delim)
Creates a single string from a List of strings seperated by a delimiter. 
if (list == null || list.size() < 1)
    return null;
StringBuffer buf = new StringBuffer();
Iterator<Object> i = list.iterator();
while (i.hasNext()) {
    buf.append((String) i.next());
    if (i.hasNext())
        buf.append(delim);
...
Stringjoin(List args, String connector)
join 
String joined = null;
for (String part : args) {
    if (joined == null) {
        joined = part;
    } else {
        joined += connector + part;
return joined;
Stringjoin(List args, String seperator)
join 
return join(args.toArray(new String[0]), seperator);
Stringjoin(List array, String delim)
Convenience routine to perform a string join for groups in the database. 
StringBuffer sb = join(array, delim, new StringBuffer());
return sb.toString();
Stringjoin(List c, String seperator)
join 
return join(new StringBuffer(), c, seperator).toString();
