java - getOption not working, constant error

I am trying to move on in my code and I am getting an error that I don't know how to fix.
The code gets to the point where it asks me for the options, then when I type, I'd like it to print 'this is letter S' or 'this is letter T' based on the input entered by the user. Pls keep in mind two things. 1) I need to use the "char getOption()" method and 2) I am new to this, so bear with me on this. The error I am getting is:

Thanks in advance.

import java.util.Scanner;

public class shapes {


   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);

      displayWelcome();
      displayMenu();
      char resp = getOption();  
         if( resp == 'S' )            
            System.out.println("This is letter S");

         else if( resp == 'T' )

            System.out.println("This is letter T");

   }      

   public static void displayWelcome() {

      System.out.println("WELCOME TO THE SHAPE PRINTER!");
      System.out.println("-----------------------------");

   }



   public static void displayMenu() {

      System.out.println("Options: ");
      System.out.println("  S)quare");
      System.out.println("  H) Shape");
      System.out.println("  T)riangle"); 
      System.out.println("  X) Shape");
      System.out.println("  Q)uit");


   }


   public static char getOption() {

      Scanner input = new Scanner(System.in);

         input.nextInt();
         char c = input.next().charAt(0);

            return c;

   }      

}
