GWT - text area - getText() - how to save some formatting?

I am just wondering... Is there an optimal way to keep "new line" formatting in TextArea? I mean when for example:

UI something like:

 ------------
|Hello world | line A (\\n)
|Hello world | line B (\\n)
|...         | line i (\\n)
 ------------

String t=ta.getText();

... so t is missing all ta "new line(s)" ; As a result t value is

Hello worldHello world...

So my question is...

How to keep "new line" format for getText() method? Or maybe there some more optimal way?

I am not pretty sure is the GWT's TextArea supports \\n lines separator. But is there a way to catch new line on fly I mean on user presses 'Enter' button? If I get text on 'Enter' was pressed no formatting is been kept. The only thing I get is a straight string but I want somehow keep line separation marks or something to restore text as it was originally in TextArea component

Thanks

If the text entered in teh textarea end with \n, then you can use

     String[] lines = yourTextArea.getText().split("\\n");// split according to new line
     for(int i=0;i<lines.length;i++)
              {
                System.out.println("lines are"+lines[i].toString());// display using toString()
              }

Is this what you are looking for??. This works if your are using java swing.
