I have created a code in java for a flower shop and now my IDE is showing all the inputs are in red showing there is an error

Question

what I am trying to accomplish is a simple menu that gets flowers + prices colours + prices and size + prices  then add it together to give you a subtotal. but in my IDE all of the  inputs are showing as red saying that input can not be resolved.

here is the code that I have done so far:

public class MenuTest2B {

// create flowers + price arrays

public static final String[] FLOWERS = {"Roses", "Lilys", "Carnations", "Daffodils", "Gerberas", "Chrysanthemums", "Assorted"};

public static final double[] FLOWER_PRICES = {1.2, 1.3, 1.0, 1.0, 1.1, 1.1, 0.8};

// create colours + price arrays

public static final String[] COLOURS = {"White", "Red", "Pink", "Yellow", "Blue", "Mixed"};

public static final double[] COLOUR_PRICES = {1.3, 1.2, 1.1, 1.1, 1.2, 1.0};

// create size + price arrays

public static final String[] SIZES = {"Small", "Medium", "Large"};

public static final double[] SIZE_PRICES = {5.5, 7.5, 9.5};

public static void main(String[] args) {

int choice;

do

{

displayMenu();

choice = getUserChoice();

switch (choice) {

case 1:

// use scanner to display menu options for flowers col ours and size

orderDetailsAndPriceCalculation();

break;

case 2:

summaryStatistics();

break;

case 3:

System.out.println("You are exiting the program... Goodbye");

break;

default:

System.out.println("Invalid input. Please select a valid option.");

}

} while (choice != 3);

}

}

private static void displayMenu() {

System.out.println("Main Menu");

System.out.println("1. Order a bouquet and get the price.");

System.out.println("2. Display statistics");

System.out.println("3. Exit");

}

public static int getUserChoice() {

int choice = -1;

try {

choice = Integer.parseInt(input.nextLine());

} catch (NumberFormatException e) {

// Invalid input, choice will remain -1

}

return choice;

}

public static void orderDetailsAndPriceCalculation() {

// adds values for chosen ammounts for orders and puts them into the scanner

int flowerChoice = getUserChoice();

int flowerchoice = input.nextInt(); input.nextLine();

if (flowerChoice == -1) return;

int colourChoice = getUserChoice();

int colourchoice = input.nextInt(); input.nextLine();

if (colourChoice == -1) return;

int sizeChoice = getUserChoice();

int sizechoice = input.nextInt(); input.nextLine();

if (sizeChoice == -1) return;

// calculates the input order details (Flower+Colour)*Size

double totalPrice = (FLOWER_PRICES[flowerChoice] + COLOUR_PRICES[colourChoice]) * SIZE_PRICES[sizeChoice];

// PRINT TOTAL AMOUNT

// AND DETAILS OF BOUQUET

System.out.println("Bouquet: " + SIZES[sizeChoice] + " " + COLOURS[colourChoice] + " " + FLOWERS[flowerChoice] + ".");

System.out.println("Bouquet Price: £" + totalPrice);

}

public static void summaryStatistics() {

System.out.println("Summary statistics provided");

}
