You'll have to redirect System.out to a custom, observable subclass of PrintStream, so that each char or line added to that stream can update the content of the textArea (I guess, this is an AWT or Swing component)

The PrintStream instance could be created with a ByteArrayOutputStream, which would collect the output of the redirected System.out
