Java Date Time - LocalDateTime.range() Examples

Class:

java.time.LocalDateTime

Method:


public ValueRange range(TemporalField field)

This method returns ValueRange object which has information of the minimum and maximum valid values for the provided field.

If the range for the field is not supported, UnsupportedTemporalTypeException is thrown.

Examples

package com.logicbig.example.localdatetime;

import java.time.LocalDateTime;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;

public class RangeExample {

    public static void main (String... args) {
        LocalDateTime d = LocalDateTime.of(2016, 12, 10,
                                           14, 30);

        ValueRange r = d.range(ChronoField.MILLI_OF_DAY);
        System.out.printf("MILLI_OF_DAY: %s%n", r);

        r = d.range(ChronoField.SECOND_OF_MINUTE);
        System.out.printf("SECOND_OF_MINUTE: %s%n", r);

        r = d.range(ChronoField.HOUR_OF_DAY);
        System.out.printf("HOUR_OF_DAY: %s%n", r);
    }

}

Output

MILLI_OF_DAY: 0 - 86399999
SECOND_OF_MINUTE: 0 - 59
HOUR_OF_DAY: 0 - 23
