import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class TxtFileReader {
    public static void main(String[] args) {
        String filePath = "path/to/your/txt/file.txt";
        ArrayList<String> lines = new ArrayList<>();

        try (BufferedReader reader = new BufferedReader(new FileReader(new File(filePath)))) {
            String line;
            while ((line = reader.readLine()) != null) {
                lines.add(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 打印读取的内容
        for (String line : lines) {
            System.out.println(line);
        }
    }
}
