```
public static String[] tokenizeToStringArray(String str,
                             String delimiters,
                             boolean trimTokens,
                             boolean ignoreEmptyTokens)
```
    Tokenize the given String into a String array via a StringTokenizer.
    The given delimiters string is supposed to consist of any number of delimiter characters. Each of those characters can be used to separate tokens. A delimiter is always a single character; for multi-character delimiters, consider using delimitedListToStringArray
    
    Parameters:
    str - the String to tokenize
    delimiters - the delimiter characters, assembled as String (each of those characters is individually considered as delimiter)
    trimTokens - trim the tokens via String's trim
    ignoreEmptyTokens - omit empty tokens from the result array (only applies to tokens that are empty after trimming; StringTokenizer will not consider subsequent delimiters as token in the first place).
    
    Returns:
    an array of the tokens (null if the input String was null)

  - delimitedListToStringArray
```
public static String[] delimitedListToStringArray(String str,
                                  String delimiter)
```
    Take a String which is a delimited list and convert it to a String array.
    A single delimiter can consists of more than one character: It will still be considered as single delimiter string, rather than as bunch of potential delimiter characters - in contrast to tokenizeToStringArray.
    
    Parameters:
    str - the input String
    delimiter - the delimiter between elements (this is a single delimiter, rather than a bunch individual delimiter characters)
    
    Returns:
    an array of the tokens in the list

```
    Take a String which is a delimited list and convert it to a String array.
    A single delimiter can consists of more than one character: It will still be considered as single delimiter string, rather than as bunch of potential delimiter characters - in contrast to tokenizeToStringArray.
    
    Parameters:
    str - the input String
    delimiter - the delimiter between elements (this is a single delimiter, rather than a bunch individual delimiter characters)
    charsToDelete - a set of characters to delete. Useful for deleting unwanted line breaks: e.g. "\r\n\f" will delete all new lines and line feeds in a String.
    
    Returns:
    an array of the tokens in the list

  - commaDelimitedListToStringArray
```
public static String[] commaDelimitedListToStringArray(String str)
```
    Convert a CSV list into an array of Strings.
    
    Parameters:
    str - the input String
    
    Returns:
    an array of Strings, or the empty array in case of empty input
  - commaDelimitedListToSet
```
public static Set<String> commaDelimitedListToSet(String str)
```
    Convenience method to convert a CSV string list to a set. Note that this will suppress duplicates.
    
    Parameters:
    str - the input String
    
    Returns:
    a Set of String entries in the list
  - collectionToDelimitedString
```
public static String collectionToDelimitedString(Collection<?> coll,

                                 String suffix)
```
    Convenience method to return a Collection as a delimited (e.g. CSV) String. E.g. useful for toString() implementations.
    
    Parameters:

    prefix - the String to start each element with
    suffix - the String to end each element with
    
    Returns:
    the delimited String
  - collectionToDelimitedString
