Im writing a program that prints a 12 month calendar for any given year. I have completed that part of the code. However i still am required to write a method that will calculate and print the exact date that thanksgiving will fall on for that given year. I am required to use switch statements.

Im working on a code that prints the calendar for any given year after the year 1800. I have finished this part of the code, it is properly compiling and in fact prints out the entire 12 month calendar for any year inputted by the user. Another part of my assignment is to be able to print out the date for thanksgiving for any particular year that is inputted by the user. I am required to use a switch statement to create this method. The method I require help on is called "thanks" and I have highlighted it blue so it is easy to find. is what needs to be able to calculate the date and then print it.

Code:
import java.util.Scanner;
public class PrintCalenderShell
{
   public static void main(String[] args)
   {
      Scanner kb = new Scanner(System.in);
      //prompt the user to enter the year
     boolean repeat = true;
     while (repeat)//repeat as long as the user wants to
     {
          int year =0;
             //loop as long as the user is entering an invalid year less than 1800
          while(year <1800) 
          { 
            System.out.println("Enter a valid year after 1800");
             //loop as long as the user is entering an input other than integer        
                 while (!kb.hasNextInt())
             {
                System.out.println("Enter a valid year after 1800:");
                kb.next();
             }
             year = kb.nextInt();
          }      
          //printing the calender for each month of the year
          for (int i =1; i<=12; i++)
          {
               //call the method printMonth with the parameters year and i
            printMonth(year, i); 
            
          } 
          System.out.println("Do you have another year to print the calender:yes/no");
          String answer = kb.next();
          if (answer.equalsIgnoreCase("no"))
              repeat = false;
     }
