Module java.base

Package java.time.format

package java.time.format

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.
