Scanner won't close

Question

I'm trying to scan String from my input stream, but it won't close. Here is my code:

public static String receive(int sid)
{
    Scanner sc = new Scanner(servers[sid].getInputStream(), "UTF-8").useDelimiter("\\A");
    String s = sc.next();
    sc.close();
    return s;

}

Answer 1

It's possible your program is getting stuck on this line:

String s = sc.next();

Have you tried using sc.hasNext() or sc.hasNextLine() to check for further data? Does the input data have an EOF character?
