在java中从文件中搜索字符串值

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

public class FileSearch {
    public static void main(String[] args) {
        String filePath = "path/to/file.txt"; // 替换为要搜索的文件路径

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            int lineNumber = 1;

            while ((line = reader.readLine()) != null) {
                if (line.contains("目标字符串")) { // 替换为要搜索的目标字符串
                    System.out.println("找到匹配的字符串：" + line);
                    // 或者将匹配的字符串保存到集合中
                }

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