Replacing multiple regexes at once

Question

Hi everybody,
I'm trying to set up a regex replace that functions like this:
String1 replaces String2
String3 replaces String4
and I'm curious, is there a way to set up a single call, like this:
replaceAll( "[String1|String3]", "[String2|String4]" )
where the one call can know which one to replace?
I know it's possible to do:
replaceAll( string1, string2 )
replaceAll( string3, string4 )
but I'm pretty sure I've seen this somewhere. Can anyone give me a hand with the syntax, if it's viable?
Thanks,

Thanks guys,
I guess that means I'll have to try the old standby of one at a time. Hmm, I wonder where I thought I saw that? Maybe I dreamed it... :)
Jezzica85You could do something like this:
public static String multipleReplacements(String text,
        String[] patterns, String[] replacements) {
    // assume patterns.length == replacements.length
    for(int i = 0; i < patterns.length; i++) {
        text = text.replaceAll(patterns, replacements[i]);
return text;
