CalenderDate Program

im needing to validate the user inputted date and should the date be invalid i must return January 1,2012 as the default date. I also need to return the day of the week that the user inputted date lands on in string form.

here is my output:

7 package calenderDate; 8 9 import java.util.; 10 11 public class Calender Date 12 Strine monthNome - (January", "February", "March","April", "May", "June", "uly","August", "September", "October, November December"): 15 int; 16 int da; 17 int yy: 18 private GregorianCalendar calen, 19 200 public static void main(String[] args) 21 22 Calender Date Date: 12 Scanner scan = new Scanner(System.in); 24 25 System.out.println("Please enter any valid date."): 2 int month - scan.nextInt(); 27 int day scan.nextInt(); int year - scan.nextInt(); 29 Date - new Calender Date(month,day, year); 30 31 System.out.println("Date: Oate.toStrine()); 32 System.out.println("Next Date: Date.nextDate()); System.out.println("Previous Date: Date.prevDate(); 16 System.out.println("The day of the week is: "Date.dayofweek()); 18 public Calender Date(int mint dd, int y) calen-new GregorianCalendar (yy, dd); CalenderDate.java 410 public Calender Date(int n, int da, int yy) 42 calen- new GregorianCalendar(yy.m, dd) 3 44 45 public String nextDate() 46 String next": 47 calen.add(GregorianCalendar.DAY_OF_MONTH, 1); 18 String month monthName[calen.get(Calendar.MONTH)-1]; 19 next month.".".calen.get(Calendar DAY_OF_MONTH) 1.calen.cet(Calendar.
