IsoChronology range() method in Java with Example

The range() method of java.time.chrono.IsoChronology class is used to get the range of from the specified field of type ChronoField.

Syntax:

public ValueRange range(ChronoField field)

Parameter: This method takes the field of type ChronoField as a parameter.

Return Value: This method returns range of from the specified field of type chrono.

Below are the examples to illustrate the range() method:

Example 1:

// Java program to demonstrate
// range() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // LocalDate Object
            LocalDate hidate = LocalDate.now();

            // getting IsoChronology
            // used in LocalDate
            IsoChronology crono
                = hidate.getChronology();

            // getting the ValueRange for
            // given ChronoField
            // by using range() method
            ValueRange range
                = crono.range(
                    ChronoField.ERA);

            // display the result
            System.out.println(
                "Equivalent Range : "
                + range);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

Output:

Equivalent Range : 0 - 1

Example 2:

// Java program to demonstrate
// range() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // LocalDate Object
            LocalDate hidate = LocalDate.now();

            // getting IsoChronology
            // used in LocalDate
            IsoChronology crono
                = hidate.getChronology();

            // getting the ValueRange for
            // given ChronoField
            // by using range() method
            ValueRange range
                = crono.range(
                    ChronoField.YEAR);

            // display the result
            System.out.println(
                "Equivalent Range : "
                + range);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

Output:

Equivalent Range : -999999999 - 999999999
