Time for an Example

Let's take an example to get length of month. Here, we are getting October month's length which is 31. So the method returns 31 as a result.

import java.time.LocalDate; 
public class DateDemo {
	
	public static void main(String[] args){  
		
		LocalDate localDate = LocalDate.of(2015, 10, 21);
		System.out.println(localDate);
		int length  = localDate.lengthOfMonth();
		System.out.println("Length of Month : "+length);
	}
}

2015-10-21
Length of Month : 31

Time for another Example

Let's take another example to understand the use of lengthOfMonth() method. Here, we are getting length of February month that has either 28 or 29. So based on the year, it returns 28 as a result.

import java.time.LocalDate; 
public class DateDemo {
	
	public static void main(String[] args){  
		
		LocalDate localDate = LocalDate.of(2015, 02, 21);
		System.out.println(localDate);
