This week's book giveaway is in the Other Open Source APIs forum. We're giving away four copies of Storm Applied and have Sean Allen, Peter Pathirana & Matthew Jankowski on-line! See this thread for details.
You are not creating an object in this statement, You are declaring a variable con that can later hold an object that implements the interface Connection.
Later in your code, you will not use: con = new Connection(), but something else. What are you doing: you are asking your database driver to give you an object that implements the Connection interface.
It's a good idea to set a breakpoint in this line of code, and see what class this object actually is.
