A class for storing dates with a constructor method

Demo Code

class Date {
  int dd;//from   w  w  w. j a v  a 2 s  .c om
  int mm;
  int yyyy;

  // Constructor (method)
  public Date(int day, int month, int year) {
    this.dd = day;
    this.mm = month;
    this.yyyy = year;
  }

}

public class Main {
  static boolean isEqual(Date d1, Date d2) {
    return (d1.dd == d2.dd && d1.mm == d2.mm & d1.yyyy == d2.yyyy);
  }

  public static void main(String[] args) {
    Date day=new Date(23,12,1971);
    System.out.println("Date:"+day.dd+"/"+day.mm+"/"+day.yyyy);

    Date day1 = new Date(23, 12, 1971);
    Date day2 = day1; // beware not copying here: shallow copying
    Date day3 = new Date(23, 12, 1971);
    System.out.println(isEqual(day1, day3));
    System.out.println(day1);
    System.out.println(day2);
    System.out.println(day3);
  }
}
