Problem with extracting price in a string

Question

String quantity = cboAmount.getSelectedItem().toString();
String product = cboProduct.getSelectedItem().toString();

String price = product.replaceAll("(\\d+(?:\\.\\d{1,2})?)", "");

textareaOrder.setText(price);

I want to extract the price from some text in a combobox, I've googled people's solutions but they all didn't work, the one in the example displays everything but the price. I don't know if I'm missing something here. The text in the combobox is written like this "Orange: 2.00" if that matters.

Tried to extract price from a string but didn't get it

So you write a regex for the price, but then you replace the thing that you found with an empty String? — f1sh, May 11 '23 at 22:06
`String price = product.replaceAll(".*?(\\d+(?:\\.\\d{1,2})?)", "$1");` but you shouldn't be bundling the two items together. It should be `JComboBox`, allowing you to extract the floating point price separately from the instance in the model — g00se, May 11 '23 at 22:36

note: Use regex to capture the prices

Java Regex Pattern

import java.util.regex.*;

public class Main {
    public static void main(String[] args) {
        String priceString = "Orange: 2.00";
        Pattern pattern = Pattern.compile("\\d+\\.\\d+");
        Matcher m = pattern.matcher(priceString);
        if (m.find()) {
            System.out.println(m.group(0));
        }
    }
}
