Question

I’m using a regex string that contains a carat (^) symbol somewhere inside of it. Is there a way in Java to remove these symbols? Here are a few methods I’ve tried:

string = "some^string";

string = string.replaceAll("\\^", "");
string = string.replaceAll(Pattern.quote("\\^"), "");
string = string.replaceAll(Pattern.quote("\u2038"), "");

None of which have worked. What am I missing?

There’s no need to use regular expressions at all:

string = string.replace("^", "");

However, the first of your examples works too:

public class Test {   
    public static void main(String[] args) throws Exception {
        String string = "some^string";
        string = string.replaceAll("\\^", "");
        System.out.println(string); // Prints somestring
    }
}

… so it’s entirely possible that your problem is elsewhere.
