仅在外括号中用逗号分割字符串的算法

Question

我只想在第一个大括号内拆分字符串。 我如何在Java中做到这一点

Input String 1: text2(text3, text4), text5(text6, text7)

String1: text2(text3, text4)
String2: text5(text6, text7)

Input String 2: text2, text3(text4, text5(text6, text7, text8))

String1: text2
String2: text3(text4, text5(text6, text7, text8))

输入字符串可以具有任意数量的级别。 请假定输入字符串具有匹配的花括号。

提前致谢

这会为您工作..吗？

导入java.util.Arrays;

class Program {
public static void main (String[] args) throws java.lang.Exception  {

    String subject1 = "text2(text3, text4), text5(text6, text7)";
    String subject2 = "text2, text3(text4, text5(text6, text7))";
    String p = "\\s*\\d*\\(\\)";
    String[] res = subject1.split(p);
    System.out.println(Arrays.toString(res));
    res=subject2.split(p);
    System.out.println(Arrays.toString(res));

} // end main
} // end 

输出：-[text2（text3，text4），text5（text6，text7）] [text2，text3（text4，text5（text6，text7））]
