    Default Array Problem

    Hi everyone. I'm trying to finish up this bit of code for some homework, but I can't quite figure out where I'm going wrong. I can get the code to print out fine, but when it goes to itemPrice = validValue[x], it's not changing the price, and defaulting to 15.50. Can someone tell me where I'm going wrong? I don't need the answer, but a nudge in the right direction would be nice. Thanks!

    import javax.swing.*;
     
    public class Main {
     
        public static void main(String[] args) {
            final double NUMBER_OF_PIZZAS = 4;
            String[] validValues = {"S", "M", "L", "X"};
            double[] prices = {6.99, 8.99, 12.50, 15.50};
            String strItem;
            int entry;
            boolean validItem = false;
            double itemPrice = 0.0;
            strItem = JOptionPane.showInputDialog(null, "Enter the pizza size you want.\nS - Small\nM - Medium\nL - Large\nX - Extra Large");
     
            for (int x = 0; x < NUMBER_OF_PIZZAS; ++x) {
                if (strItem.equalsIgnoreCase(validValues[x])) {
                    validItem = true;
                    itemPrice = prices[x];
          }
     
            }
     
     
            if (validItem) {
                JOptionPane.showMessageDialog(null, "The price of a " + strItem + " pizza is $" + itemPrice);
            } else {
                JOptionPane.showMessageDialog(null, "That's not a valid pizza");
            }
        }
    }

    The code you posted should work as expected, and just to be sure I ran it and it worked as expected.

    I found an extra pair of brackets. I think my IDE might not have been compiling it correctly or something. Oh well. Thanks for your help!
