Java String Help!!

Rather simple.

I have this string:

A, b747 ||), (C, a300 -- --), (Y, a300 -- ||

I need to replace in it, "), (" with "\n" but I can't find anything that can.

Ive tried String.replace('(', '\n');

but then you can't replace ' ' & '(' with ''.

Ive looked at:
public String replaceAll(String regex, String replacement)
but that doesnt seem to help me because...

ns = ns.replaceAll("), (", "\n");
it compiles fine, but throws this...
java.util.regex.PatternSyntaxException: Unmatched closing ')'

You need to use regular expression syntax to use that replaceAll method. There should be something about it in the java docs.

Failing that you could do it using indexOf, substring and a StringBuffer.

Code:

ns = ns.replaceAll("\\), \\(", "\n");

Like this

Code:

    public static String replaceSubstring(String str, String sub, String with) {
        int length = sub.length();
        for (int i=str.indexOf(sub); i!=-1; i=str.indexOf(sub)) {
            StringBuffer strbuf = new StringBuffer(str).replace(i, i+length, with);
            str = strbuf.toString();
        }
        return (str);
    }

Edit: Ah... i was wondering why i would write my own method when there was already a replaceAll, its cause replaceAll isn't in JDK1.3 only 1.4+
