ChronoPeriod get() method in Java with Examples

The get() method of ChronoPeriod interface in Java is used to get the value of the requested unit(YEARS, MONTHS or DAYS) given in the argument from this ChronoPeriod.

Syntax:

long get(TemporalUnit unit)

Parameters: This method accepts a single parameter unit of type TemporalUnit which is the unit to get required unit.

Return Value: This function returns the long value of the requested unit.

Exceptions:

• DateTimeException – This method throws DateTimeException, if the unit in argument is not supported.
• UnsupportedTemporalTypeException – This method throws UnsupportedTemporalTypeException if the unit given in argument is not supported.

Below programs illustrate the above method:

Program 1:

// Java code to show the function get()
// which gives the requested unit

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodDemo {

    // Function to get requested unit
    static void getUnit(int year, int months, int days)
    {
        ChronoPeriod period = Period.of(year, months, days);
        System.out.println(period.get(ChronoUnit.DAYS));
    }

    // Driver Code
    public static void main(String[] args)
    {

        int year = 8;
        int months = 5;
        int days = 25;

        getUnit(year, months, days);
    }
}

Output:

25

Program 2:

// Java code to show the function get()
// which gives the requested unit

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodDemo {

    // Function to get requested unit
    static void getUnit(int year, int months, int days)
    {
        ChronoPeriod period = Period.of(year, months, days);
        System.out.println(period.get(ChronoUnit.YEARS));
    }

    // Driver Code
    public static void main(String[] args)
    {

        int year = 11;
        int months = 3;
        int days = 21;

        getUnit(year, months, days);
    }
}

Output:

11
