java.time.format
Stay organized with collections
Save and categorize content based on your preferences.
Provides classes to print and parse dates and times.
Printing and parsing is based around the
DateTimeFormatter class.
Instances are generally obtained from
DateTimeFormatter, however
DateTimeFormatterBuilder
can be used if more power is needed.
Localization occurs by calling
withLocale(Locale)
on the formatter. Further customization is possible using
DecimalStyle.
Package specification
Unless otherwise noted, passing a null argument to a constructor or method in any class or interface
in this package will cause a NullPointerException to be thrown.
The Javadoc "@param" definition is used to summarise the null-behavior.
The "@throws NullPointerException" is not explicitly documented in each method.
All calculations should check for numeric overflow and throw either an ArithmeticException
or a DateTimeException.
