Well, just what the error message tells you - you cannot use the
concatenation
operator (That's only valid for instances of String).
A DefaultStyledDocument is not a String. It is not text; it is pattern
describing
Perhaps you are trying to concatenate a String representation of a number
to the text contained within some portion of the document?
If so, see the getText() and insertText() methods of DefaultStyledDocument.
