I want to read de characters in an array : ok but I want them to
display on the screen with OutputStreamWriter, but
nothing happens, what's wrong. I know there's a better way, but I want
to do it this way.

public class IO
{

    public static void main (String[]args)
    {
      System.out.println("Geef een zin in");
          Writer uitvoer = new  OutputStreamWriter(System.out); //
streaming to screen

     char[]buf = new char[250];
     Reader invoer = new InputStreamReader(System.in);

      try{
            invoer.read(buf); //ok
            uitvoer.write(buf); //nothing appear
      }
      catch(IOException ioe)
      {
        System.out.println("fout bij inlezen");

      }
