java – 使用BufferedReader和Scanner读取文本文件

如果你真的需要同时使用BufferedReader和Scanner,你可以这样做：

byte[] inputBytes = "line 1nline 2nline 3ntok 1 tok 2".getBytes();
Reader r = new InputStreamReader(new ByteArrayInputStream(inputBytes));

BufferedReader br = new BufferedReader(r);
Scanner s = new Scanner(br);

System.out.println("First line:  " + br.readLine());
System.out.println("Second line: " + br.readLine());
System.out.println("Third line:  " + br.readLine());

System.out.println("Remaining tokens:");
while (s.hasNext())
    System.out.println(s.next());

输出：

First line:  line 1    // from BufferedReader
Second line: line 2    // from BufferedReader
Third line:  line 3    // from BufferedReader
Remaining tokens:
tok                    // from Scanner
1                      // from Scanner
tok                    // from Scanner
2                      // from Scanner
