LocalDate lengthOfMonth() method in Java

The length of the month in a particular LocalDate is obtained using the method lengthOfMonth() in the LocalDate class in Java. This method requires no parameters and it returns the length of the month in a particular LocalDate i.e. 28, 29, 30 or 31.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.*;
public class Main {
   public static void main(String[] args) {
      LocalDate ld = LocalDate.parse("2019-02-15");
      System.out.println("The LocalDate is: " + ld);
      System.out.println("The length of the month is: " + ld.lengthOfMonth());
   }
}

Output

The LocalDate is: 2019-02-15
The length of the month is: 28

Now let us understand the above program.

First the LocalDate is displayed. Then the length of the month in the LocalDate is obtained using the method lengthOfMonth() and displayed. A code snippet that demonstrates this is as follows −

LocalDate ld = LocalDate.parse("2019-02-15");
System.out.println("The LocalDate is: " + ld);
System.out.println("The length of the month is: " + ld.lengthOfMonth());
