Java LocalDate range() Method
Java range() method is used to get the range of valid values for the specified field. The range value expresses the minimum and maximum valid values for a field. For example, if we want to get the number of days in the month of October then we get a range 1-31 for this month.
We can use ChronoField enum as an argument to get a range of the specified field. The ChronoField enum has the following values:

Syntax
public ValueRange range(TemporalField field)
Parameters:
field - the field to query the range for.
Returns:
It returns the range of valid values for the field.
Time for an Example:
Let's take an example to get the range of the month in the date. We are using ChronoField enum to get a range by using the range() method.
import java.time.LocalDate;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;
public class DateDemo {
public static void main(String[] args){
LocalDate localDate = LocalDate.of(2012, 02, 29);
System.out.println(localDate);
ValueRange vr = localDate.range(ChronoField.DAY_OF_MONTH);
System.out.println("Range : "+vr);
}
}
2012年02月29日
Range : 1 - 29
Time for another Example:
Let's take another example to understand the range() method. Here, we are getting range of the year in the date and getting range from 1 to 366.
import java.time.LocalDate;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;
public class DateDemo {
public static void main(String[] args){
LocalDate localDate = LocalDate.of(2012, 02, 29);
System.out.println(localDate);
ValueRange vr = localDate.range(ChronoField.DAY_OF_YEAR);
System.out.println("Range : "+vr);
}
}
2012年02月29日
Range : 1 - 366
