Question

question related to this

I have a string

a\\;b\\\\;c;d

which in Java looks like

String s = \"a\\\\;b\\\\\\\\;c;d\"         


        

Answer 1

This approach assumes that your string will not have char '\0' in your string. If you do, you can use some other char.

public static String[] split(String s) {
    String[] result = s.replaceAll("([^\\\\])\\\\;", "$1\0").split(";");
    for (int i = 0; i < result.length; i++) {
        result[i] = result[i].replaceAll("\0", "\\\\;");
    }
    return result;
}
