Method to locate row and column in TableView

Question

In a TableView.setOnMouseClicked ()
How to capture that row and column were clicked?

Answer 1

I am having problem in populating data from a table in one screen to a Text Field in the other screen. I have two classes FirstClass containing a textbox and a button. On pressing a button a second window is opened containing a Table of values. As the user double clicks a row the value of the second column of the row should be inserted into the textbox of the FirstClass. Code of both the classes is attached. Thanking you in anticipation.
