How to Convert String to Double in Java

Question

I want to convert a string (for example $4.50) to a double. I understand I can use Double.parseDouble() but I assume this works only if the string does not contain any other chars (such as the dollar sign). The purpose is to compare two Strings (which contain dollar values plus a dollar sign) and determine which one is greater and which one is smaller

How can I convert such a string to a double?

You really should spend a few minutes googling your own question before posting. — JeffC

Use Double.parseDouble after removing the unwanted characters like currency symbols.

Double.parseDouble(string.replaceAll("[^\\d.]", ""));

This would removed any character but not of a dot or a digit.
