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.
An abstract method is implicitly a virtual method. Abstract method declarations are only permitted in abstract classes. The implementation is provided by an overriding method, which is a member of a non-abstract class. It is an error to use the static or virtual modifiers in an abstract method declaration.
