public class EnumDemo { private enum Day { MONDAY(1), TUESDAY(2), WEDNESDAY(3), THURSDAY(4), FRIDAY(5), SATURDAY(6), SUNDAY(7); private int whichDay; /* * Constructor of enum type is private. If you don't * declare private compiler internally creates * private constructor. */ private Day(int whichDay) { this.whichDay = whichDay; } } public static void main(String[] args) { /* * The java compiler internally adds the values() * method when it creates an enum. The values() * method returns an array containing all the values * of the enum. */ Day[] daysArray = Day.values(); for (Day day : daysArray) { System.out.println(day + " is which day? " + day.whichDay); } } }Output
