Java Utililty Methods Array to String

StringBuffer sB = new StringBuffer();
if (array.length > 0 ) {
    for (String i : array) {
        sB.append(i);
        sB.append(System.getProperty("path.separator")); 
return sB.toString();
...

This takes a String[] and returns a String that can be converted back into an identical String[] using the stringToArray method.

StringBuffer sb = new StringBuffer();
for (int i = 0; i < array.length; i++) {
    sb.append(stuffString(array[i]));
    if (i < array.length - 1)
        sb.append("\"\\\"");
return sb.toString();

String result = "{ ";
for (String data : array) {
    result += data + ", ";
result += " }";
return result;

String ret = "";
for (int i = start; i < array.length; i++) {
    if (i < array.length - 1) {
        ret += array[i] + delimiter;
    } else {
        ret += array[i];
return ret;

StringBuilder result;
String quot = quotes ? "'" : "";
if (array.length == 0)
    return "";
result = new StringBuilder();
for (String elem : array) {
    result.append(quot + elem + quot + delim);
result.deleteCharAt(result.length() - 1);
return result.toString();

return arrayToString((Object[]) array, separator);

StringBuilder builder = new StringBuilder();
for (int i = 0; i < array.length; i++) {
    if (i != 0) {
        builder.append(separator);
    builder.append(array[i]);
return builder.toString();
...

StringBuffer sb = new StringBuffer("");
String empty = "";
if (array == null)
    return empty;
if (separators == null)
    separators = ",";
for (int ix = 0; ix < array.length; ix++) {
    if (array[ix] != null && !array[ix].equals("")) {
...

StringBuilder sb = new StringBuilder();
if (arrayString == null || arrayString.length == 0) {
    return null;
for (int i = 0; i < arrayString.length; i++) {
    if (arrayString[i] != null && arrayString[i].length() > 0) {
        if (sb.length() > 0) {
            sb.append(splitStr);
...

String output = "";
for (int i = 0; i < input.length; i++) {
    output += input[i];
    output += System.lineSeparator();
return output;
