Java Date Time - LocalDate.get() Examples

Java Date Time Java Java API 

PreviousNext

Class:

java.time.LocalDate

java.lang.Objectjava.lang.Objectjava.time.LocalDatejava.time.LocalDatejava.time.temporal.TemporalTemporaljava.time.temporal.TemporalAdjusterTemporalAdjusterjava.time.chrono.ChronoLocalDateChronoLocalDatejava.io.SerializableSerializableLogicBig

Method:

public int get(TemporalField field)

It returns the value of the specified field from 'this' instance. If the provided TemporalField is not supported, UnsupportedTemporalTypeException is thrown.

The supported fields will return true from isSupported() method.

EPOCH_DAY and PROLEPTIC_MONTH are too large to fit in an int, there we should use getLong() method instead.

This method is defined in the interface TemporalAccessor which is a super interface of ChronoLocalDate.


Examples


package com.logicbig.example.localdate;

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.ChronoField;

public class GetExample {
    public static void main (String[] args) {
        LocalDate d = LocalDate.of(2010, Month.AUGUST, 20);

        int i = d.get(ChronoField.DAY_OF_MONTH);
        System.out.println("DAY_OF_MONTH = " + i);

        i = d.get(ChronoField.DAY_OF_YEAR);
        System.out.println("DAY_OF_YEAR = " + i);

        i = d.get(ChronoField.DAY_OF_WEEK);
        System.out.print("DAY_OF_WEEK = " + i);
        System.out.println(", DayOfWeek = "+ DayOfWeek.of(i));

        i = d.get(ChronoField.ALIGNED_DAY_OF_WEEK_IN_MONTH);
        System.out.print("ALIGNED_DAY_OF_WEEK_IN_MONTH = " + i);
        System.out.println(", DayOfWeek = "+ DayOfWeek.of(i));

        i = d.get(ChronoField.ALIGNED_DAY_OF_WEEK_IN_YEAR);
        System.out.print("ALIGNED_DAY_OF_WEEK_IN_YEAR = " + i);
        System.out.println(", DayOfWeek = "+ DayOfWeek.of(i));

        i = d.get(ChronoField.ALIGNED_WEEK_OF_MONTH);
        System.out.println("ALIGNED_WEEK_OF_MONTH = " + i);

        i = d.get(ChronoField.ALIGNED_WEEK_OF_YEAR);
        System.out.println("ALIGNED_WEEK_OF_YEAR = " + i);

        i = d.get(ChronoField.MONTH_OF_YEAR);
        System.out.println("MONTH_OF_YEAR = " + i);

        i = d.get(ChronoField.YEAR_OF_ERA);
        System.out.println("YEAR_OF_ERA = " + i);

        i = d.get(ChronoField.YEAR);
        System.out.println("YEAR = " + i);

        i = d.get(ChronoField.ERA);
        System.out.println("ERA = " + i);
    }
}

Output

DAY_OF_MONTH = 20
DAY_OF_YEAR = 232
DAY_OF_WEEK = 5, DayOfWeek = FRIDAY
ALIGNED_DAY_OF_WEEK_IN_MONTH = 6, DayOfWeek = SATURDAY
ALIGNED_DAY_OF_WEEK_IN_YEAR = 1, DayOfWeek = MONDAY
ALIGNED_WEEK_OF_MONTH = 3
ALIGNED_WEEK_OF_YEAR = 34
MONTH_OF_YEAR = 8
YEAR_OF_ERA = 2010
YEAR = 2010
ERA = 1
