boolean notFirst = false;
for (Map.Entry<?, ?> entry : map.entrySet()) {
    if (notFirst) {
        stringBuilder.append(',');

StringjoinMapToString(Map map, String sSeparator, String sMidSeparator)
join Map To String 
StringBuilder sb = new StringBuilder();
Iterator it = map.entrySet().iterator();
boolean First = true;
while (it.hasNext()) {
    Map.Entry tmpEntry = (Map.Entry) it.next();
    if (First) {
        First = false;
    } else {
...
MapjoinMapUnmodifiable(Map first, Map second)
Join the two given maps to one by checking if one of the two maps already fulfills everything. 
if (first == null || first.isEmpty()) {
    if (second == null || second.isEmpty()) {
        return Collections.emptyMap();
    } else {
        return Collections.unmodifiableMap(second);
} else if (second == null || second.isEmpty()) {
    return Collections.unmodifiableMap(first);
...
StringjoinMapValue(Map map, char connector)
join Map Value 
StringBuffer b = new StringBuffer();
for (Map.Entry<String, String> entry : map.entrySet()) {
    b.append(entry.getKey());
    b.append('=');
    if (entry.getValue() != null) {
        b.append(entry.getValue());
    b.append(connector);
...
StringjoinOnDelimiter(Map toJoin, char delimiter)
Convert properties to a string representation, based on the specified delimiter. 
StringBuffer buf = new StringBuffer();
for (Iterator it = toJoin.entrySet().iterator(); it.hasNext();) {
    Map.Entry e = (Map.Entry) it.next();
    String key = (String) e.getKey();
    String value = (String) e.getValue();

StringBuilder bob = new StringBuilder();
for (Entry<String, String> e : params.entrySet()) {
    bob.append("&");
    bob.append(e.getKey());
    bob.append("=");
    bob.append(e.getValue());
return bob.substring(1);
