Thread: How to clear the textArea?

Hi everyone,

Thanks in advance

        Searcher searchIT = new Searcher(search1, area, search, found);//sets listner for search1 JButton
 
        FindIt.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//so program will close when x is clicked

    }
    public static void main(String[] args)
    {
        FindIt word = new FindIt();
    }
}

I already read it, and I've tried many things, I couldn't find any solution yet . Anyway, thanks

Have a look here. Reading that should help you.

This is realy easy, the only thing you should do is setting the text to a string that contains nothing.
So you should do is : textField.setText(""); in the actionlistener of the button.
Then the field wil be set to nothing.

Except it's not a text field, it's a text area.
