不会接受字符数组在这个测验

Question

我试图将其转换为字符，但我仍然遇到了一个问题，它不会正确构建，新手在这里。但任何帮助请做

import java.util.Scanner; 

public class PizzaChoice { 

    public static void main(String[] args){ 
     //char sizes; 
     Scanner input = new Scanner(System.in); 
     final int NUMBER_OF_CHOICES = 4; 
     char[] pizzaSize = {'S', 'M', 'L', 'X'}; 
     double[] prices = {6.99, 8.99, 12.50, 15.00}; 
     char sizeChosen; 
     double pizzaPrice = 0.0; 
     boolean validChoice = false; 
     Scanner inputDevice = new Scanner(System.in); 
     System.out.print("Enter pizza size- S, M, L, or X: "); 
     sizeChosen = inputDevice.nextLine().charAt(0); 
     for(int s = 0; s < NUMBER_OF_CHOICES; ++s) 
     {  
      if(sizeChosen.equals(pizzaSize[s])) 
      { 
       validChoice = true; 
       pizzaPrice = prices[s]; 
      } 
     } 
     if(validChoice) 
      System.out.println("The price for chosen size " + 
        sizeChosen + " is $" + pizzaPrice); 
     else 
      System.out.println("Sorry - Invalid Choice Entered"); 

    } 

}

替换字符的pizzaSize和sizeChosen字符，它会工作。见"Char cannot be dereferenced" error
