Text goes outside JTextArea

问题

I am trying to do something in Java which requires me to have a JTextArea in a ScrollPane.

Here is how I have defined them:

private JTextArea longestparagraph = new JTextArea();

....
JScrollPane scrollpanedreapta = new JScrollPane(longestparagraph, 
                        JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, 
                        JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
scrollpanedreapta.setBorder(BorderFactory.createTitledBorder("Cel mai lung paragraf:"));

The problem I'm encountering is that the text doesn't start on a new line when it reaches the right border of the TextArea but it continues. Got any ideas how to solve that? Here's a picture to make my statement a little bit clearer.

Found the answer. Just had to this:

longestparagraph.setLineWrap(true);
longestparagraph.setWrapStyleWord(true);
