StringBuilder	appendTo(StringBuilder builder, Map<?,?> map) Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to builder.
String	join(Map<?,?> map) Returns a string containing the string representation of each entry of map, using the previously configured separator and key-value separator.
