Method:

public static ZonedDateTime from(TemporalAccessor temporal)

This static method returns the ZonedDateTime instance based on the provided TemporalAccessor.

The provided temporal accessor must have all fields needed for the OffsetDateTime instance creation otherwise DateTimeException will be thrown.


Examples


package com.logicbig.example.zoneddatetime;

import java.time.OffsetDateTime;
import java.time.ZonedDateTime;

public class FromExample {

    public static void main(String... args) {
        OffsetDateTime date = OffsetDateTime.now();
        System.out.println(date);

        ZonedDateTime zdt = ZonedDateTime.from(date);
        System.out.println(zdt);
    }
}

Output
