JTextArea in JTextPane - Want new line

I want to add text to a JTextArea, and to have an auto scrollbar on vertical.

but when typing horizonally, I want an auto new line when there is no space in line.. If I use only JTextArea it's OK, but when I put it in a JScrollPane, it is not make a new line when needed.

How can I do that?

Thanks!

By default, a JTextArea will not wrap text so you have to manually define that behavior:

textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);

Also, make sure you're setting up the JScrollPane correctly:

JScrollPane sp = new JScrollPane(textArea);

//JScrollPanes are just like JPanels (except for the scrollbars) so be careful not to just add the JComponent to your frame; add the container instead.

frame.add(sp);

As a side note, read the tutorial @kleopatra so helpfully suggested to get a good solid base on textareas.

you have to configure the textArea to wrap:

textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);

You might consider reading a basic tutorial to get you started effectively :-)

Isn't JTextArea implementing the Scrollable interface? So why you need JScrollPane?

Edit to your comment, this one works for me:

JScrollPane sP= new JScrollPane(txtarea);
sP.setBounds(10,60,780,500);
sP.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
