Java 8 LocalDate Class Introduction | Java Date and Time | Java 8 Date and Time

LocalDateDemo1.java

import java.time.LocalDate;

public class LocalDateDemo1
{

    public static void main(String[] args)
    {
        /*
         * Returns:the current date using the system clock and default
         * time-zone, not null
         */

        LocalDate localDate = LocalDate.now();
        System.out.println(localDate);
        System.out.println("Year = " + localDate.getYear());
        System.out.println("Month = " + localDate.getMonthValue());
        System.out.println&#4 0;"DayOfMonth = " + localDate.getDayOfMonth());
        System.out.println("DayOfWeek = " + localDate.getDayOfWeek());

    }

}

Output

2018-01-03
Year = 2018
Month = 1
DayOfMonth = 3
DayOfWeek = WEDNESDAY

LocalDateDemo2.java

import java.time.LocalDate;

public class LocalDateDemo2
{

    public static void main(String[] args)
    {
        /*
         * Parameters:
         *
         * year - the year to represent, from MIN_YEAR to MAX_YEAR
         *
         * month - the month-of-year to represent, from 1 (January) to
         * 12 (December)
         *
         * dayOfMonth - the day-of-month to represent, from 1 to 31
         *
         * Returns:the local date, not null
         */

        LocalDate localDate = LocalDate.of(2027, 7, 25);
        System.out.println(localDate);

    }

}

Output

2027-07-25

LocalDateDemo3.java

import java.time.LocalDate;

public class LocalDateDemo3
{

         *
         * text - the text to parse such as "2007-12-03", not null
         *
         * Returns:

         * the parsed local date, not null
         *
         */
