Method:

public static LocalTime from(TemporalAccessor temporal)

The static method LocalTime.from(TemporalAccessor temporal) returns the LocalTime instance based on the provided TemporalAccessor.

The provided temporal accessor must have all fields needed for the LocalTime instance to be created otherwise DateTimeException will be thrown.



Examples


package com.logicbig.example.localtime;

import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.ZoneId;
import java.time.ZonedDateTime;

public class FromExample {

    public static void main (String... args) {
        ZonedDateTime z = ZonedDateTime.of(2016, 10, 12,
                                           15, 20, 30, 0,
                                           ZoneId.systemDefault());
        System.out.println(z);

        LocalTime t2 = LocalTime.from(z);
        System.out.println(t2);
    }
}
