Morphing class deprecated??

Question

I have been working with a Morphing example found on the internet (posted below) and when I go to compile the code, I get the following warning:
"javax.media.j3d.Morph in javax.media.j3d has been deprecated"
Java 3D is fully functioning on my pc, so it isn't a case of java3d being missing.
Can anyone help explain? Any help would be greatly appreciated, Thanks.

Answer 1

A method or (in this case it seems) a class being deprecated is nothing to worry about. All it means is that it is strongly advised that you not use this method/class because they have made something better to use. It also means that support for the method/class is no longer available from the makers and that they will soon be discontinuing the method/class.
In the case of the Morph class, you can still use it, but it may not be there in the next version or two. If you want to stop those compile warnings, then you can stick this somewhere (before the method that uses the Morph, I think):
@SuppressWarnings("unused")Using that will Suppress further Warnings of any "unused" (read "no longer supported/deprecated") classes or methods. And in your next program, see if you can find a replacement for the Morph class.
