如何在Java中提取写在文件中的数据结尾

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class FileDataExtractor {
    public static void main(String[] args) {
        String filePath = "path/to/your/file.txt"; // 文件路径

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            String targetDataEnd = ""; // 目标数据结尾

            while ((line = reader.readLine()) != null) {
                if (line.endsWith("targetDataEnd")) { // 判断是否包含目标数据结尾
                    targetDataEnd = line.substring(line.indexOf("targetDataEnd") + "targetDataEnd".length());
                }
            }

            System.out.println("提取到的数据结尾：" + targetDataEnd);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
