java - 如何使用 Java 标准 API 从字符串中获取特定数据？

Question

我有以下模式:

Jan(COMPANY) &^% Feb(ASP) 567 Mar(INC) 

我希望最终的输出是:

String[] one = {"Jan", "Feb", "Mar"};
String[] two = {"COMPANY","ASP","INC"};

请帮忙。有人吗!!？

将结果存储在 String[] one 和 String[] Two 中的完整示例如下所示:

import java.util.*;
import java.util.regex.*;

public class Main {
    public static void main(String[] args) {

        String str = "Jan(COMPANY) &^% Feb(ASP) 567 Mar(INC)";

        ArrayList<String> monthArr = new ArrayList<String>();
        ArrayList<String> dataArr  = new ArrayList<String>();

        // Part 1: \\b(\\p{Alpha}+): Word boundary, one or more characters
        // Part 2: \\(([^)]+)\\): "(", anything but ")" one or more times, ")" 
        Pattern p = Pattern.compile("\\b(\\p{Alpha}+)\\(([^)]+)\\)");
        Matcher m = p.matcher(str);

        while (m.find()) {
            monthArr.add(m.group(1));  // m.group(1) = "Jan", "Feb" and so on
            dataArr.add(m.group(2));   // m.group(2) = "COMPANY, "ASP", and so on
        }

        String[] one = monthArr.toArray(new String[0]);
        String[] two = dataArr.toArray(new String[0]);
    }
}
