java – 如何从字符串中提取以下模式？

{(firstName1,lastName1,College1,{(24,25)},{(Street,23)},City1,Country1)}

我需要从上面提取细节/值并将它们添加到列表中.我的意思是：

["firstName1","lastName1","College1","24","25","Street","23","City1","country1"]

我怎样才能实现上述目标？我尝试了下面的方法,但不知道如何将所有花括号和括号放入模式中.

private static String flattenPigBag(String pigdata) {
    String s = "";
    Pattern p = Pattern.compile("{(.*)}");
    Matcher m = p.matcher(pigdata);
    while (m.find()) {
        s = m.group(1);
        System.out.println("answer : " + s);
    }
    return s;
}
