How to pass from method to arguments to main and get the day of the week

Question

Hi
Need some help, this code below doesnt fit the requirement.
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
Code
import java.util.*;
public class App2 {
    private int day;
    private int month;
    private int year;
         private int inputDay;
            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
          Date today = df.parse(date);               
          System.out.println("Today = " + df.format(today));
          catch(ParseException e)
          if(month2.equals("01") || month2.equals("1")){month2 = "January";}              
          else if(month2.equals("02") || month2.equals("2")){month2 = "February";}              
          else if(month2.equals("03") || month2.equals("3")){month2 = "March";}              
          else if(month2.equals("04") || month2.equals("4")){month2 = "April";}              
          else if(month2.equals("05") || month2.equals("5")){month2 = "May";}              
          else if(month2.equals("06") || month2.equals("6")){month2 = "June";}              
          else if(month2.equals("07") || month2.equals("7")){month2 = "July";}              
          else if(month2.equals("08") || month2.equals("8")){month2 = "August";}              
          else if(month2.equals("09") || month2.equals("9")){month2 = "September";}              
          else if(month2.equals("10")){month2 = "October";}              
          else if(month2.equals("11")){month2 = "November";}              
          else if(month2.equals("12")){month2 = "December";}
          return month2;
    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);
}Program output: 29 Aug 2010 is a Sunday
