```
public class DateTimeFormatterBuilder
extends java.lang.Object
```
Factory that creates complex instances of DateTimeFormatter via method calls.
Datetime formatting is performed by the DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are DateTimeFormat and ISODateTimeFormat.
DateTimeFormatterBuilder is used for constructing formatters which are then used to print or parse. The formatters are built by appending specific fields or other formatters to an instance of this builder.
For example, a formatter that prints month and year, like "January 1970", can be constructed as follows:
```
 DateTimeFormatter monthAndYear = new DateTimeFormatterBuilder()
     .appendMonthOfYearText()
     .appendLiteral(' ')
     .appendYear(4, 4)
     .toFormatter();
 
```
DateTimeFormatterBuilder itself is mutable and not thread-safe, but the formatters that it builds are thread-safe and immutable.

```
public DateTimeFormatter toFormatter()
```
    Constructs a DateTimeFormatter using all the appended elements.
    This is the main method used by applications at the end of the build process to create a usable formatter.
    Subsequent changes to this builder do not affect the returned formatter.
    The returned formatter may not support both printing and parsing. The methods DateTimeFormatter.isPrinter() and DateTimeFormatter.isParser() will help you determine the state of the formatter.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if neither printing nor parsing is supported
  - toPrinter
```
public DateTimePrinter toPrinter()
```
    Internal method to create a DateTimePrinter instance using all the appended elements.
    Most applications will not use this method. If you want a printer in an application, call toFormatter() and just use the printing API.

public DateTimeFormatterBuilder append(DateTimePrinter printer,
                                       DateTimeParser[] parsers)
```
    Appends a printer and a set of matching parsers. When parsing, the first parser in the list is selected for parsing. If it fails, the next is chosen, and so on. If none of these parsers succeeds, then the failed position of the parser that made the greatest progress is returned.
    Only the printer is optional. In addition, it is illegal for any but the last of the parser array elements to be null. If the last element is null, this represents the empty parser. The presence of an empty parser indicates that the entire array of parse formats is optional.

```
public DateTimeFormatterBuilder appendFraction(DateTimeFieldType fieldType,
                                               int minDigits,
                                               int maxDigits)
```
    Instructs the printer to emit a remainder of time as a decimal fraction, without decimal point. For example, if the field is specified as minuteOfHour and the time is 12:30:45, the value printed is 75. A decimal point is implied, so the fraction is 0.75, or three-quarters of a minute.
    
    Parameters:
    
    fieldType - type of field to append
    
    minDigits - minimum number of digits to print.
    
    maxDigits - maximum number of digits to print or parse.

```
public DateTimeFormatterBuilder appendFractionOfSecond(int minDigits,
                                                       int maxDigits)
```
    Appends the print/parse of a fractional second.
    This reliably handles the case where fractional digits are being handled beyond a visible decimal point. The digits parsed will always be treated as the most significant (numerically largest) digits. Thus '23' will be parsed as 230 milliseconds. Contrast this behaviour to appendMillisOfSecond(int). This method does not print or parse the decimal point itself.
    
    Parameters:
    
    minDigits - minimum number of digits to print
    
    maxDigits - maximum number of digits to print or parse
    
    Returns:
    
    this DateTimeFormatterBuilder, for chaining
  - appendFractionOfMinute
```
public DateTimeFormatterBuilder appendFractionOfMinute(int minDigits,
                                                       int maxDigits)
```
    Appends the print/parse of a fractional minute.
    This reliably handles the case where fractional digits are being handled beyond a visible decimal point. The digits parsed will always be treated as the most significant (numerically largest) digits. Thus '23' will be parsed as 0.23 minutes (converted to milliseconds). This method does not print or parse the decimal point itself.
    
    Parameters:
    
    minDigits - minimum number of digits to print
    
    maxDigits - maximum number of digits to print or parse
    
    Returns:
    
    this DateTimeFormatterBuilder, for chaining
  - appendFractionOfHour
```
public DateTimeFormatterBuilder appendFractionOfHour(int minDigits,
                                                     int maxDigits)
```
    Appends the print/parse of a fractional hour.
    This reliably handles the case where fractional digits are being handled beyond a visible decimal point. The digits parsed will always be treated as the most significant (numerically largest) digits. Thus '23' will be parsed as 0.23 hours (converted to milliseconds). This method does not print or parse the decimal point itself.
    
    Parameters:
    
    minDigits - minimum number of digits to print
    
    maxDigits - maximum number of digits to print or parse
    
    Returns:
    
    this DateTimeFormatterBuilder, for chaining
  - appendFractionOfDay
```
public DateTimeFormatterBuilder appendFractionOfDay(int minDigits,
                                                    int maxDigits)
```
    Appends the print/parse of a fractional day.
    This reliably handles the case where fractional digits are being handled beyond a visible decimal point. The digits parsed will always be treated as the most significant (numerically largest) digits. Thus '23' will be parsed as 0.23 days (converted to milliseconds). This method does not print or parse the decimal point itself.
    
    Parameters:
    
    minDigits - minimum number of digits to print
    
    maxDigits - maximum number of digits to print or parse
    
    Returns:
    
    this DateTimeFormatterBuilder, for chaining
  - appendMillisOfSecond
```
public DateTimeFormatterBuilder appendMillisOfSecond(int minDigits)
```
    Instructs the printer to emit a numeric millisOfSecond field.
    This method will append a field that prints a three digit value. During parsing the value that is parsed is assumed to be three digits. If less than three digits are present then they will be counted as the smallest parts of the millisecond. This is probably not what you want if you are using the field as a fraction. Instead, a fractional millisecond should be produced using appendFractionOfSecond(int, int).
    
    Parameters:
    
    minDigits - minimum number of digits to print
    
    Returns:
    
    this DateTimeFormatterBuilder, for chaining
  - appendMillisOfDay

```
    Instructs the printer to emit text and numbers to display time zone offset from UTC. A parser will use the parsed time zone offset to adjust the datetime.
    If zero offset print text is supplied, then it will be printed when the zone is zero. If zero offset parse text is supplied, then either it or the offset will be parsed.
    
    Parameters:
    
    zeroOffsetPrintText - the text to print if time zone offset is zero. If null, offset is always shown.
    
    zeroOffsetParseText - the text to optionally parse to indicate that the time zone offset is zero. If null, then always use the offset.
    
    showSeparators - if true, prints ':' separator before minute and second field and prints '.' separator before fraction field.
    
    minFields - minimum number of fields to print, stopping when no more precision is required. 1=hours, 2=minutes, 3=seconds, 4=fraction
    
    maxFields - maximum number of fields to print
