Split a string after some specific sub-string in Java using regex

String str = "FirstName LastName - 1234xx"

In above case, want to replace above string with everything after " - " substring. In the above example it would mean changing str to 1234xx

The length of string after " - " is not fixed, hence cannot just capture last certain no. of characters

This approach gives FirstName LastName - - instead of desired output 1234xx

public class StringExample 
{
    public static void main(String[] args) 
    {
        String str = "FirstName LastName - 1234xx";
        String newStr = str.replaceAll("(?<=( - )).*", "$1");

        System.out.println(newStr);
    }
}

You were on the right track. Just use a lazy dot to consume everything up to and including the dash.

String str = "FirstName LastName - 1234xx";
String newStr = str.replaceAll("^.*-\\s*", "");

System.out.println(newStr);
