这篇具有很好参考价值的文章主要介绍了java 逐行读取文件(读取文件每一行、按行读取文件)附带示例代码。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

BufferedReader

最快的读取每一行

	@Test
    public void bufferReaderTest() {
        try (BufferedReader bufferedReader = new BufferedReader(new FileReader("D:\\aa.txt"))) {
            String line;
            while ((line = bufferedReader.readLine())  != null) {
                // 处理每一行数据 .....
            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

Scanner

相比较Scanner慢一点

 	@Test
    public void scannerTest() {
        try (Scanner scanner = new Scanner(new File("D:\\aa.txt"))) {
            while (scanner.hasNextLine()) {
                // 处理每一行数据 .....
                String line = scanner.nextLine();

            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

RandomAccessFile

行数达到一定规模，使用此方法读取会非常慢

	@Test
    public void randomAccessFileTest() {
        try (RandomAccessFile accessFile = new RandomAccessFile("D:\\aa.txt", "r")) {
            String line;
            while ((line = accessFile.readLine()) != null) {
                // 处理每一行数据 .....

            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

Files

一次把所有数据都读到内存中，当文件非常大时，会消耗掉内存资源导致程序崩掉，文件规模小推荐使用

	@Test
    public void filesTest() {
        try {
            List<String> lines = Files.readAllLines(Paths.get("D:\\aa.txt"));
            lines.forEach(line -> {
                // 处理每一行数据 .....

            });
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

  • C++：ifstream通过getline读取文件会忽略最后一行空行

    getline是读取文件的常用函数，虽然使用简单，但是有一个较容易被忽视的问题，就是文件最后一行空行会被忽略。  假设文件abc.txt内容为 123 456 789 最后没有空行 运行程序输出： 1{123} 2{456} 3{789}  可以看到读到了3行完整的内容  假设文件abc.txt内容为 123 456 789 最后有一行空行
