LocalDateTime range() method in Java

Java 8Object Oriented ProgrammingProgramming

The range of values for a ChronoField can be obtained using the range() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the ChronoField for which the range of values is required and it returns the range of values.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.*;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;
public class Main {
   public static void main(String[] args) {
      LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:19:50");
      System.out.println("The LocalDateTime is: " + ldt);
      ValueRange dowRange = ldt.range(ChronoField.DAY_OF_WEEK);
      System.out.println("The range of DAY_OF_WEEK: " + dowRange);
   }
}

Output

The LocalDateTime is: 2019-02-18T11:19:50
The range of DAY_OF_WEEK: 1 - 7

Now let us understand the above program.

First the LocalDateTime is displayed. Then the range of values of a particular ChronoField are obtained using the range() method and displayed. A code snippet that demonstrates this is as follows −

LocalDateTime ldt = LocalDateTime.parse("2019-02-18T11:19:50");
System.out.println("The LocalDateTime is: " + ldt);
ValueRange dowRange = ldt.range(ChronoField.DAY_OF_WEEK);
System.out.println("The range of DAY_OF_WEEK: " + dowRange);
