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.
Note that the abstract keyword is used to denote both an abstract method, and an abstract class. Now, any animal that wants to be instantiated (like a dog or cow) must implement the makeNoise method-otherwise it is impossible to create an instance of that class.
