I don't have TerminalIO, so I've changed that part of the code, perhaps you can incorporate part of this
import java.io.*;
public class Grocery
  public static void main (String [] args)
    BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
    double items[] = {.5,1.0,2.5};
    String item, quantity;
    double totalcost;
    String continueShopping = "Y";
    while(continueShopping.toUpperCase().equals("Y"))
      try
        System.out.print("Apple is 1; Bread is 2; Milk is 3\nEnter Item: ");
        item = stdin.readLine();
        System.out.print("\nEnter Quantity: ");
        quantity = stdin.readLine();
        totalcost = items[Integer.parseInt(item)-1] * Integer.parseInt(quantity);
        System.out.println("Total is: " + totalcost);
        System.out.print("\nContinue shopping? (y/n)");
        continueShopping = stdin.readLine();
      catch(Exception e)
        System.out.println("Error - invalid data, terminating");
    System.exit(0);
}
