Example:

// Java program to demonstrate the example 
// of getDayOfMonth() method of LocalDateTime

import java.time.*;

public class GetDayOfMonthOfLocalDateTime {
    public static void main(String args[]) {
        // Instantiates two LocalDateTime
        LocalDateTime da_ti1 = LocalDateTime.parse("2005-10-05T10:10:10");
        LocalDateTime da_ti2 = LocalDateTime.now();

        // Display da_ti1, da_ti2
        System.out.println("LocalDateTime da_ti1 and da_ti2: ");
        System.out.println("da_ti1: " + da_ti1);
        System.out.println("da_ti2: " + da_ti2);

        System.out.println();

        // Here, this method returns the field
        // value day-of-month from this date-time
        // object (da_ti1)
        int dom = da_ti1.getDayOfMonth();

        // Display dom
        System.out.println("da_ti1.getDayOfMonth(): " + dom);

        // Here, this method returns the field value'
        // day-of-month from this date-time
        // object (da_ti2)
        dom = da_ti2.getDayOfMonth();

        // Display dom
        System.out.println("da_ti2.getDayOfMonth(): " + dom);
    }
}

Output

LocalDateTime da_ti1 and da_ti2: 
da_ti1: 2005-10-05T10:10:10
da_ti2: 2020-06-05T02:28:12.790951

da_ti1.getDayOfMonth(): 5
da_ti2.getDayOfMonth(): 5
