Last Updated :

The isFixed() method of ValueRange class is used to check the value range is fixed and fully known or not.For example, the ChronoField day-of-month runs from 1 to between 28 and 31. The maximum value of day-of-month is not fixed, there is uncertainty about it. However, for the month of December, the range is always 1 to 31, thus it is fixed.
Syntax:
public boolean isFixed()
Parameters: This method accepts nothing.
Return value: This method returns true if the set of values is fixed.
Below programs illustrate the ValueRange.isFixed() method:
Program 1:
import java.time.LocalDateTime;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;
public class GFG {
public static void main(String[] args)
{
LocalDateTime l1
= LocalDateTime
.parse( "2018-12-06T19:21:12" );
ValueRange vR
= l1.range(ChronoField.DAY_OF_MONTH);
boolean response = vR.isFixed();
System.out.println( "isFixed: "
+ response);
}
}

Program 2:
import java.time.temporal.ValueRange;
public class GFG {
public static void main(String[] args)
{
ValueRange vRange = ValueRange.of( 1111 , 66666 );
boolean response = vRange.isFixed();
System.out.println( "isFixed: "
+ response);
}
}
