Java SE (Java Platform, Standard Edition)

Hello,

If I have a JTextarea and I display a whole book in it, is it possible to implement a search function. Like for example a JTextfield, where I could type a word and the press a button and all the matches in the JTextarea are highlited and the JTextarea goes to the first match.
Also, would it be possible to have a JComboBox with the chapters of the book, and then when I choose one, the JTextArea goes down to that chapter ?

If anybody can tell me if this is possible, and maybe give a few pointers or links, where I can read about this, I would be very thankful.
