StringtoString(Object[] array)
to String 
return toString(array, ", ");
StringtoString(Object[] array)
Create a string representation of the given array 
StringBuffer buf = new StringBuffer();
buf.append(": ");
for (int i = 0; i < array.length; i++) {
    buf.append("[");
    buf.append(i);
    buf.append("]: ");
    buf.append((array[i] == null) ? "null" : array[i]);
    buf.append(" ");
...
StringtoString(Object[] objects)
to String 
return join(", ", objects);
StringtoString(String arrayName, T[] targets)
Constructs a String representation of an array and its values. 
final int n = targets.length;
StringBuilder sb = new StringBuilder();
sb.append(arrayName).append(" { ");
for (int i = 0; i < n; i++) {
    sb.append(targets[i].toString());
    if (i + 1 < n)
        sb.append(",");
    sb.append(" ");
...
StringtoString(String[] args, char color1, char color2)
to String 
StringBuilder stringBuilder = new StringBuilder();
if (args.length > 1) {
    for (int iii = 0; iii < args.length - 1; iii++) {
        stringBuilder.append("\247");
        stringBuilder.append(color1);
        stringBuilder.append(args[iii]);
        stringBuilder.append("\247");
        stringBuilder.append(color2);

StringtoString(String[] arguments)
Provides a debug helper for printing out all arguments of a process for error tracking. 
StringBuffer call = new StringBuffer();
for (int j = 0; j < arguments.length; j++) {
    String arg = arguments[j];
    if (arg.indexOf(' ') != -1) {
        call.append('"').append(arg).append('"');
    } else {
        call.append(arg);
    call.append(' ');
return call.toString();
StringtoString(String[] array, String delimiter)
Converts an array of string to a string concatenation separated by the given delimiter. 
if (array == null || array.length == 0) {
    return null;
StringBuffer sb = new StringBuffer();
for (int i = 0; i < array.length; i++) {
    sb.append(array[i]);
    if (i != array.length - 1) {
        sb.append(delimiter);
...
StringtoString(String[] line)
to String 
if (line == null)
    return "";
StringBuilder str = new StringBuilder(512);
for (int i = 0; i < line.length; ++i) {
    if (i != 0)
        str.append(',');
    str.append(line[i]);
if (str.length() > 0)
    str.append("\n");
return str.toString();
StringtoString(String[] paramNames, Object[] params)
Converts the parameters to string. 
StringBuffer sb = new StringBuffer(" Input parameters: {");
if (params != null) {
    for (int i = 0; i < params.length; i++) {
        if (i > 0) {
            sb.append(", ");
