Below programs illustrate the ChronoField.range() method:
Program 1:






// 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 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
