Need help to split string in java using regex

Question

I have a string like "portal100common2055".

I would like to split this into two parts, where the second part should only contain numbers.

"portal200511sbet104" would become "portal200511sbet", "104"

Can you please help me to achieve this?

Like this:

    Matcher m = Pattern.compile("^(.*?)(\\d+)$").matcher(args[0]);
    if( m.find() ) {
        String prefix = m.group(1);
        String digits = m.group(2);
        System.out.println("Prefix is \""+prefix+"\"");
        System.out.println("Trailing digits are \""+digits+"\"");
    } else {
        System.out.println("Does not match");
    }
