java - Java Inputstream，NoFly服务器

Question

我有一个输入流，看起来像“true Name true Name true Name ... false” [由 boolean 值和字符串组成]。我需要从流中读取一个名称，直到达到假。我试图使用不推荐使用的.readLine()方法并使用bufferedreader来做到这一点，但两者似乎都无法处理任务。我一直在获取NameNameName字符串，但是我需要三个单独的Name字符串。

代码

private final DataInputStream in;
private final DataOutputStream out;
private final Collection<String> names;

//there is more code above, it's a request handler for a NoFly Server.

private void doRequest(Function<String, Boolean> fn) throws IOException {

    while(in.readBoolean() && !Thread.interrupted()) {
        //here I need to read the name
        names.add(name);
        //dont mind the function
        boolean val = fn.apply(name);
        System.out.println(val + name);
        out.writeChars(name);
        out.writeBoolean(val);
    }
}

假设您输入的是 boolean 值和字符串(由“”分隔)的一致性序列。您可以尝试:

     //input sequence of (boolean, String), (..., ...), ...
    InputStream input = new ByteArrayInputStream("true Name true Name true Name false NameNotDisplayedFalse true NameNotDisplayedTrue".getBytes());
    Scanner sc = new Scanner(input).useDelimiter("\\A");
    String str = sc.hasNext() ? sc.next() : "";
    //input delimiter
    String sArray[] = str.split(" ");


    if (sArray.length < 2) {
        return;
    }
    int i = 1;
    while (i < sArray.length && !sArray[i-1].equals("false")) {
        //you can access name here
        System.out.println(sArray[i]);
        i+=2;
    }

输出:

姓名

姓名

姓名
