Get the day of the week & month in word from constructor into main with input

Hi

i need to modify this code to fit the requirement.....any help and sample would be appreciated..
For this program, i need to: take in day, month,year of a date as int argument, return the day of the week for the date entered in App()

In Main: call the App() to get the day of the week to display when user enter the date in dd/mm/yyyy
StringTokenizer is required for this program.

- How can the arguments pass back to main by returning of month & day of the week?
- Program cant take in int and return as string
- Date cant display day of the week

Program output: 29 Aug 2010 is a Sunday

Code:

        private int inputMonth; 
        private int inputYear; 
     
    public static String App2(String day2, String month2, String year2) { // this is wrong should pass int in 
     
        String date = day2 + month2 + year2; 
        DateFormat df = new SimpleDateFormat("dd/MM/yyyy");     
                     
        try 
        {

        System.out.println("Today = " + df.format(today));   
        } 
        catch(ParseException e) 
        { 
        } 
             
          if(month2.equals("01") || month2.equals("1")){month2 = "January";}

          else if(month2.equals("12")){month2 = "December";} 
           
        return month2;  // can only return month, how abt day of week?
    } 
    public static void main (String [ ] args){ 
        Scanner sc = new Scanner(System.in); 
        System.out.print("Enter the date in dd/mm/yyyy: "); 
        String date = sc.nextLine(); 
        StringTokenizer st = new StringTokenizer(date, "/");   
        String day = st.nextToken(); 
        String month = st.nextToken(); 
        String year = st.nextToken(); 
        App2(day, month, year); 
        String test = App2(day, month, year); 
            System.out.print(test);  //can get month Aug
    } 
}

First, to get the day of the week, create a second SimpleDateFormat and use the E format to get the day of the week. (See SimpleDateFormat (Java 2 Platform SE v1.4.2).)

Second, to pass them as integers, you'll want to take a look at Integer.parseInt (Java 2 Platform SE v1.4.2).

Third, you only need to call App2(day,month,year) once (the second one is correct); you call it twice. If this is a school assignment you may be marked down for calling it twice.
