dos output

[jesse jay]

I am running the jdk thru a dos window but I am having the following trouble.....when I have output, it is much larger then the output window, even if i make the window size huge and the text tiny, is there anything in dos that is similar to the cat command on unix so I could capture the i/o to a file and then review it.
any help appreciated
thanks in advance

Yes, you can redirect the output of your program to any outputstream that you wish.

public static void main(String args[])
{  
   try
   {
      FileOutputStream fos = new FileOutputStream("Output.txt");
      PrintWriter pout = new PrintWriter(fos);
      System.setOut(pout);
      //the rest of your code as it exists now
      pout.close();
   }
   catch(IOException ioe)
   {
      ioe.printStackTrace();
   }
}

Hope this helps

OK, DOS like most operating systems allows you to 'pipe' the output of programs(as long as the program doesn't take additional control) The charater that is used for a redirect is >
java saveScreenOutput > output.txt
You can also 'pipe' input using the <.
Hope this helps
