Introduction to Java Development
********************************
-Last updated: 28 February, 2013.

As of OpenCV 2.4.4, OpenCV supports desktop Java development using nearly the same interface as for
Android development. This guide will help you to create your first Java (or Scala) application using OpenCV.

Now let's look at the possiblity of using OpenCV in Java when developing in Eclipse IDE.
