    Default Trying to modify class so when toString method returns in different format than given

    So I'm trying to get a return in the format "month number, number" ex. February 11, 2012. In the beginning I enter all in numbers. I'm stumped on where to begin. Should I create an string array ?
    public class DaysBetween
    {
      public static void main(String[] args)
      {
     
        Scanner conIn = new Scanner(System.in);
        int day, month, year;
        boolean cont = true;
        String input;
        do	// Added do while loop, so user gets asked if he wants to repeat operation.
        {
        	    System.out.println("Enter two 'modern' dates: month day year");
        		System.out.println("For example, January 12, 1954, would be: 1 12 1954");
        		System.out.println();
        		System.out.println("Modern dates occur after " + Date.MINYEAR + ".");
        		System.out.println();
     
        		System.out.println("Enter the first date:");
        		if(conIn.hasNextInt())
        		{
        				month = conIn.nextInt();
    	 				day = conIn.nextInt();
        				year = conIn.nextInt();
        				Date date1 = new Date(month, day, year);
     
        		}
        			else
        			{
        				conIn.next();
        				System.out.print("Illegal input was entered. ");
        				return;
        			}
     
     
        		System.out.println("Enter the second date:");
        			month = conIn.nextInt();
        			day = conIn.nextInt();
        			year = conIn.nextInt();
        		Date date2 = new Date(month, day, year);
     
     
     
        	if  ((date1.getYear() <= Date.MINYEAR) /////Cannot find symbol
    	    		||
    		 	(date2.getYear() <= Date.MINYEAR))
          		System.out.println("You entered a 'pre-modern' date.");
        	else
        		{
          			System.out.println("The number of days between");
          			System.out.print(date1); /////Cannot find symbol
          			System.out.print(" and ");
          			System.out.print(date2);
          			System.out.print(" is ");
          			System.out.println(Math.abs(date1.lilian() - date2.lilian()));///Cannot find symbol
          			System.out.print("and it has been ");
          			System.out.print(Math.abs(date2.mjd())); // Added to print days between now and Nov 17, 1858.
          			System.out.println(" days since November 17, 1858");
          			System.out.print("and it has been ");
          			System.out.print(Math.abs(date2.djd())); // Added to print days between now and Jan 1, 1900.
          			System.out.println(" days since January 1, 1900");
          			System.out.print("Do you want to continue? (Y/N): "); // Added to ask user if they want to continue.
     
        		}
        }
        while ("Y".equalsIgnoreCase(conIn.next().trim())); //Added so if user enters "yes" program will start over.
     }
    }

    Edit: I have figured out the problem with my toString method, but have encountered another problem. I am supposed to verify that the input are integers and if not, I'm supposed to tell user "wrong input" and close. I thought I can put a if-else statment, but when I build I get an error "Cannot find symbol" refering to date1 in the 2nd "if" statement. Any clue on what I'm doing wrong?

    Hey slayer,

    Do you mind reading This? It makes it lot easier for us to help you.

    What type of parameter is your toString method receiving? What is it's purpose?
    Simplicity calls for Complexity. Think about it.
