  - parse
```
public static Kontonummer parse(String accountCode)
                         throws ParseException
```
    Parses text from the beginning of the given string to produce a Kontonummer.
    Unlike the parse(String, ParsePosition) method this method throws a ParseException if accountCode cannot be parsed or is of invalid length.
    
    Parameters:
    accountCode - A Kontonummer in either electronic or letter format.
    
    Returns:
    The parsed value.
    
    Throws:
    
    NullPointerException - if accountCode is null.
    
    ParseException - if the parse fails or accountCode is of invalid length.
  - parse
```
public static Kontonummer parse(String accountCode,
                ParsePosition pos)
```
    Parses text from a string to produce a Kontonummer.
    The method attempts to parse text starting at the index given by pos. If parsing succeeds, then the index of pos is updated to the index after the last character used (parsing does not necessarily use all characters up to the end of the string), and the parsed value is returned. The updated pos can be used to indicate the starting point for the next call to this method.
    
    Parameters:
    accountCode - A Kontonummer in either electronic or letter format.
    pos - A ParsePosition object with index and error index information as described above.
    
    Returns:
    The parsed value, or null if the parse fails.
    
    Throws:
    
    NullPointerException - if either accountCode or pos is null.
  - toString
```
public String toString()
```
    Returns a string representation of the object.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    A string representation of the object.
  - toString
```
public static String toString(Kontonummer kontonummer)
```
    Formats a Kontonummer to produce a string. Same as
    kontonummer.format(ELECTRONIC_FORMAT)
    
    Parameters:
    kontonummer - The Kontonummer instance to format.
    
    Returns:
    The formatted string.
    
    Throws:
    
    NullPointerException - if kontonummer is null.
  - valueOf
```
public static Kontonummer valueOf(Number accountCode)
```
    Returns an instance for the Kontonummer identified by the given number.
    
    Parameters:
    accountCode - A number identifying a Kontonummer.
    
    Returns:
    An instance for accountCode.
    
    Throws:
    
    NullPointerException - if accountCode is null.
    
    IllegalArgumentException - if accountCode is negative, zero or greater than 9999999999.
    See Also:
    checkKontonummer(Number)
  - valueOf
```
public static Kontonummer valueOf(String accountCode)
```
    Parses text from the beginning of the given string to produce a Kontonummer.
    Unlike the parse(String) method this method throws an IllegalArgumentException if accountCode cannot be parsed or is of invalid length.
    
    Parameters:
    accountCode - A Kontonummer in either electronic or letter format.
    
    Returns:
    The parsed value.
    
    Throws:
    
    NullPointerException - if accountCode is null.
    
    IllegalArgumentException - if the parse fails or accountCode is of invalid length.
