JapaneseChronology zonedDateTime(TemporalAccessor) method in Java with Example

The zonedDateTime() method of java.time.chrono.JapaneseChronology class is used get the zonal date and time according to Japanese calendar system from the another TemporalAccessor object.

Syntax:

public ZonedDateTime zonedDateTime(
          TemporalAccessor temporal)

Parameter: This method takes the object of any temporal accessor as a parameter.

Return Value: This method returns the ZonedDateTime according to the Japanese calendar system from another TemporalAccessor object.

Below are the examples to illustrate the zonedDateTime() method:
