<u>Abstract method declaration</u>
abstract void moveTo(double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.

Answer:
To create a nonlinear presentation that had external links the designer should include “hyperlinks”
Explanation:
Let us understand what non-linear presentation is. It’s a reverse of linear presentation. A linear will go slide by slide, without any jump. A non-linear slide is a type of presentation prepared when the flow of slide is not much important, and the presenter can jump to any of the slide from any slide. This is done thorough two ways. 1. Hyperlink 2. Action button
We must include hyperlinks or action buttons where it allows us to toggle or navigate to any of the slide within the file. The hyperlink can also be added to move the control to a website.
