how to read from standard input non-blocking?

Question

    long end=System.currentTimeMillis()+60*10;
    InputStreamReader fileInputStream=new InputStreamReader(System.in);
    BufferedReader bufferedReader=new Buffered         


        

Answer 1

BufferReader.readLine() can block for a very long time if a line is extremely long like 1M chars.

Does your file contains such long lines?

If yes, you may have to break up the lines, or use per-char read methods like BufferReader.read().
