Insertion in JTextArea

[P Jain]

Hi!
I have a JTextArea which has some strings(each string in new line).
I clicks at some location in JTextArea after this I click one Button.I want to insert a text by button click on the next line of the location where I last click the mouse(in JTextArea).

lets the contents of JTextArea is

Cricket
FootBall
Tennis

when I click on the line of FootBall and then clicks on button then text "Text" should be inserted as

Cricket
FootBall
Text
Tennis


How I can do that.

        f.getContentPane().add(north, "North");
        f.getContentPane().add(textArea);
        f.setSize(400,400);
