ChronoField range() method in Java with Examples

Last Updated : 29 Jan, 2020
The range() method of ChronoField enum is used to return the range of valid values for the ChronoField constant.All fields of this range can be expressed as a long integer. Syntax: 
public ValueRange range()
Parameters: This method accepts nothing. Return value: This method returns the range of valid values for the field, not null. Below programs illustrate the ChronoField.range() method: Program 1: Java 
// Java program to demonstrate
// ChronoField.range() method

import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {

        // get chronoField
        ChronoField chronoField
            = ChronoField.valueOf("HOUR_OF_DAY");

        // apply range()
        ValueRange rangeAttribute
            = chronoField.range();

        // print
        System.out.println("ValueRange for HOUR_OF_DAY"
                           + " is :"
                           + rangeAttribute);
    }
}
Output: 
ValueRange for HOUR_OF_DAY is :0 - 23
Program 2: Java 
// Java program to demonstrate
// ChronoField.range() method

import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {

        // get chronoField
        ChronoField chronoField
            = ChronoField.valueOf("YEAR_OF_ERA");

        // apply range()
        ValueRange rangeAttribute
            = chronoField.range();

        // print
        System.out.println("ValueRange for YEAR_OF_ERA"
                           + " is:"
                           + rangeAttribute);
    }
}
Output: 
ValueRange for YEAR_OF_ERA is:1 - 999999999/1000000000
