Java를 사용하여 txt 문서를 읽는 방법

<code class="java">File file = new File("path/to/file.txt");</code>

<code class="java">FileReader reader = new FileReader(file);</code>

<code class="java">BufferedReader bufferedReader = new BufferedReader(reader);</code>

<code class="java">String line;
while ((line = bufferedReader.readLine()) != null) {
    // 读取到的文本行存储在 line 变量中
}</code>

<code class="java">bufferedReader.close();
reader.close();</code>

<code class="java">import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;

public class ReadTxtFile {

    public static void main(String[] args) {
        try {
            // 创建文件对象
            File file = new File("path/to/file.txt");

            // 创建文件读取器
            FileReader reader = new FileReader(file);

            // 创建缓冲读取器
            BufferedReader bufferedReader = new BufferedReader(reader);

            // 逐行读取数据
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                // 读取到的文本行存储在 line 变量中
                System.out.println(line);
            }

            // 关闭读取器
            bufferedReader.close();
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
