Just save it to a variable. Of course it will be overwritten each time in the loop

String savedString = buffer;

How about:

String store="";
while( (buffer=input.readLine())!=null)
{   store+=buffer;
    display.appendText("\n"+buffer);
}

This will put the whole input into the String named stored.

String buffer = null ;
   StringBuffer todisplay = new StringBuffer();
        while( ( buffer = input.readLine() ) != null )
          todisplay.append( "\n" + buffer ) ;
          }
    display.setText(todisplay.toString());

use following if you want to append the read text:

display.appendText(todisplay.toString());

It's already stored in a variable in your question.  It's stored in "buffer".

If 'display' is a text component like a TextArea then it's stored anyway and you can get it back as follows:

String original = display.getText();

> It's stored in "buffer".

Not the entire string read.

> String original = display.getText();

That returns the string displayed in the text field, and not the string read in.

>>That returns the string displayed in the text field, and not the string read in.

The value, if taken just after the text field is set, is exactly the same as the value contained in the StringBuffer 'todisplay' that you suggested, which is redundant if 'display' is a text component of some kind, as the String is already buffered.

>>display.appendText()

'display' can't be of type String, as it does not have an appendText method
