java逐行讀取文件(讀取文件每一行、按行讀取文件)附帶詳細(xì)代碼

這篇文章主要給大家介紹了關(guān)于java逐行讀取文件(讀取文件每一行、按行讀取文件)的相關(guān)資料,讀取文件是我們?cè)谌粘９ぷ髦薪?jīng)常遇到的一個(gè)需求,文中通過(guò)代碼介紹的非常詳細(xì),需要的朋友可以參考下

BufferedReader

最快的讀取每一行

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

Scanner

相比較Scanner慢一點(diǎn)

 	@Test
    public void scannerTest() {
        try (Scanner scanner = new Scanner(new File("D:\\aa.txt"))) {
            while (scanner.hasNextLine()) {
                // 處理每一行數(shù)據(jù) .....
                String line = scanner.nextLine();
            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

RandomAccessFile

行數(shù)達(dá)到一定規(guī)模，使用此方法讀取會(huì)非常慢

@Test
    public void randomAccessFileTest() {
        try (RandomAccessFile accessFile = new RandomAccessFile("D:\\aa.txt", "r")) {
            String line;
            while ((line = accessFile.readLine()) != null) {
                // 處理每一行數(shù)據(jù) .....
            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

Files

一次把所有數(shù)據(jù)都讀到內(nèi)存中，當(dāng)文件非常大時(shí)，會(huì)消耗掉內(nèi)存資源導(dǎo)致程序崩掉，文件規(guī)模小推薦使用

@Test
    public void filesTest() {
        try {
            List<String> lines = Files.readAllLines(Paths.get("D:\\aa.txt"));
            lines.forEach(line -> {
                // 處理每一行數(shù)據(jù) .....
            });
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

示例代碼

統(tǒng)計(jì)每一行日志ip出現(xiàn)的次數(shù)
