We would like to know how to get day information.

Answer

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.format.TextStyle;
import java.util.Locale;
/*  www  .  j  a  v a2 s .c om*/
public class Main {

  public static void main(String[] args) {
    LocalDate date = LocalDate.of(2014, 2, 15); // 2014-02-15
    // ISO-8601 standard
    // the day-of-week to represent, from 1 (Monday) to 7 (Sunday)
    DayOfWeek dayOfWeek = date.getDayOfWeek();
    System.out.println(dayOfWeek); // SATURDAY

    System.out.println(DayOfWeek.of(3)); // WEDNESDAY

    System.out.println(dayOfWeek.getValue()); // 6
    System.out.println(dayOfWeek.name()); // SATURDAY

    System.out.println(date.getDayOfMonth()); // 15
    System.out.println(date.atStartOfDay()); // 2014-02-15 00:00

    System.out.println("DayOfWeek");
    dayOfWeek = DayOfWeek.FRIDAY;
    Locale locale = Locale.getDefault();
    System.out.println(dayOfWeek.getDisplayName(TextStyle.FULL, locale)); // Friday
    System.out.println(dayOfWeek.getDisplayName(TextStyle.NARROW, locale)); // F
    System.out.println(dayOfWeek.getDisplayName(TextStyle.SHORT, locale)); // Fri
  }
}

The code above generates the following result.
