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.
There are more aspects (interface: only public methods, abstract class: protected abstract and public abstract methods) but you can read that for yourself. On a final note, an abstract class that only provides abstract methods is a pure abstract base class, aka, an interface.
