如何在java中从一个文件中抓取并显示两个字符串(模式)之间的多行

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class FileContentExtractor {
    public static void main(String[] args) {
        String filePath = "path/to/your/file.txt"; // 替换为你的文件路径
        String startPattern = "开始模式"; // 替换为你的开始模式
        String endPattern = "结束模式"; // 替换为你的结束模式

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            StringBuilder content = new StringBuilder();
            String line;
            boolean insideBlock = false;
            Pattern startRegex = Pattern.compile(startPattern);
            Pattern endRegex = Pattern.compile(endPattern);

            while ((line = reader.readLine()) != null) {
                Matcher startMatcher = startRegex.matcher(line);
                Matcher endMatcher = endRegex.matcher(line);

                if (startMatcher.find()) {
                    insideBlock = true;
                }

                if (insideBlock) {
                    content.append(line).append("\n");
                }

                if (endMatcher.find()) {
                    insideBlock = false;
                    break; // 找到结束模式后退出循环
                }
            }

            System.out.println(content.toString());

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
