    Default How to replace dollar signs with ""?

    I have a program that prompts the user for an entry and they could potentially enter in a lot of things, but I want to catch the dollar signs and convert them to "" in terms of strings. I've tried using the replace method on my string like:

    input.replace("$", "");

    But that obviously doesn't work. What can I do to achieve this? What if there are multiple dollar signs? Is there a method on String which I can call to replace all dollar signs?

    Try
    String.replaceAll(String statement, String replacement)

    String (Java 2 Platform SE v1.4.2)

    If you read the API for String you would notice that the replace methods return a new String with the replacement carried out.
    So all you need to do is assign the replaced version back to input.
