通過bufferedReader 讀行

public static void readByBufferedReader() throws IOException {FileReader fileReader = new FileReader("/Users/jmeter.log");BufferedReader bufferedReader = new BufferedReader(fileReader);String st;while ((st = bufferedReader.readLine()) != null) {System.out.println(st);} } 復制代碼

FileReader 讀字節

public static void readbyFileReader() throws IOException {FileReader fileReader = new FileReader("/Users//jmeter.log");int temp;while ((temp = fileReader.read()) != -1) {System.out.print((char) temp);}} 復制代碼

Scanner

public static void readByScanner() throws FileNotFoundException {Scanner scanner = new Scanner(new File("/Users//jmeter.log"));while (scanner.hasNext()) {System.out.println("test");System.out.println(scanner.nextLine());} } 復制代碼

readAllLines

public static void readByFiles() throws IOException {ArrayList list = (ArrayList) Files.readAllLines(Paths.get("/Users//jmeter.log"));list.forEach((a) -> System.out.println(a));} 復制代碼
