Having issues with handling text field

Question

I have one requirement where text field have information like below format:

String name = 'email,phone(Jason),mobile,address(Mason)';

Now what I want to do is create a Map<Key, List<String>> where key will be name in brackets ex: Jason/Mason and values will be whatever is before that name in parentheses. So output should be like:

OUTPUT: {Jason=(email,Phone), Mason=(mobile,address)}

I had tried different ways but unable to format string 'email,phone(Jason), mobile,address(Mason)'. As there are parentheses Is it even possible to achieve this?

That's an oddly weird request, but assuming you haven't overgeneralized, you could write something like this:

Map<String, List<String>> results = new Map<String, List<String>>();
String name = 'email,phone(Jason),mobile,address(Mason)';
while(name != '') {
    String key = name.substringBetween('(',')');
    String[] values = name.substringBefore('(').split(',');
    results.put(key, values);
    name = name.substringAfter(')').removeStart(',');
}

Which outputs:

{Jason=(email, phone), Mason=(mobile, address)}
