String is Immutable in Java. You have to reassign it to get the result back:

String str ="your string with dashesh";
str= str.replace("\u2014", "");

See the API for details.

this simply works..

    String str = "String-with-dash-";
    str=str.replace("-", "");
    System.out.println(str);

output - Stringwithdash

It's quite easy. You can use an Apache library, that will be useful while you develop an application. This is apache-commons-lang. You can do the following:

public class Main {

    public static void main(String[] args) {

        String test = "Dash - string";
        String withoutDash = StringUtils.replace(test, "-", "");
        System.out.println(withoutDash);
    }

}

the apache commons lang library is a bit overkill to replace a dash in a string, java manages fine on its own – flup Jul 20 '13 at 12:04
Yes, but did you see my comment ? "that will be useful while you develop an application" That's why I proposed this solution – Lefteris Bab Jul 20 '13 at 12:21
