Java Utililty Methods Vector to String

if (source == null || separator == null) {
    return null;
StringBuffer sb = new StringBuffer("");
int si = source.size();
for (int i = 0; i < si; i++) {
    sb.append(source.elementAt(i).toString());
    if ((i + 1) < si) {
...

if (vector == null)
    return new String[0];
String[] arr = new String[vector.size()];
for (int i = 0; i < vector.size(); i++)
    arr[i] = vector.elementAt(i).toString();
return arr;

if ((V == null) || (V.size() == 0)) {
    final String[] s = new String[0];
    return s;
final String[] s = new String[V.size()];
for (int v = 0; v < V.size(); v++)
    s[v] = V.elementAt(v).toString();
return s;
...

if (v == null) {
    return null;
String s = "";
for (int i = 0; i < v.size(); i++) {
    s += (i > 0 ? sep : "") + v.get(i);
return s;
...

if (v == null || delimiter == null) {
    return null;
return enumeration2String(v.elements(), delimiter);

int len = v.size();
String[] ret = new String[len];
for (int i = 0; i < len; i++) {
    ret[i] = v.elementAt(i).toString();
return ret;

This method returns a string containing all the elements in vec concatenated together, comma separated.

if (vec == null) {
    return "";
StringBuffer temp = new StringBuffer();
for (int i = 0; i < vec.size(); i++) {
    if (i > 0) {
        temp.append(",");
    temp.append(vec.elementAt(i));
return temp.toString();

int i, j;
String line;
i = 0;
j = 0;
int sz = nicksAndPaths.size();
String[] result_buffer = new String[sz];
String temp;
while (i < sz) {
...

return ("( " + v[0] + ", " + v[1] + ", " + v[2] + " )");

String str = "[";
for (int i = 0; i < v.length; i++)
    str += v[i] + ((i < v.length - 1) ? ", " : "");
return str + "]";
