Publicationdate July 1, 2009. The aim of this presentation is to demonstrate imaging findings of common diseases of the temporal bone. CT is the imaging modality of choice for most of the pathologic conditions of the temporal bone, especially for those of the middle ear. MRI is more useful for diseases of the inner ear. Disease processes in the pontine angle and in the internal acoustic meatus are not discussed.
Java allows an instance of an abstract class to be instantiated. Late binding refers to the method definition being associated with the method invocation when the method is invoked at run time. Early binding enables the compiler to be more efficient.
Use of Java [Interfaces / Abstract classes] You can think of an interface as a contract. You are defining a set of methods that classes which implement this interface must implement. An abstract class, on the other hand, is used when you have some code that could be common to all the child classes you want to implement. So you might have an abstract class called Shape that has some common code, and in your derived classes (Circle, Square, etc.) you could have the code that is specific to those shapes (getArea would be an example).
