This is a unique feature in JAVA.as the name itself
suggests that it is related with run time.In this classes
has methods with same method name and signature.However
which method will b executed will be decided during run
Java uses this fact to resolve calls to overridden methods
at run time. Here’s
how. When an overridden method is called through a
superclass reference, Java determines
which version of that method to execute based upon the type
of the object being referred to at the
time the call occurs. Thus, this determination is made at
run time with the help of dynamic method dispatch .
