Method Redefinition in ABAP Objects

The method that has already been defined in the superclass can be redefined within the
subclass .When a super class method is redefined within the sub –class then the method
name export import parameters remain the same but the method implemetation changes
.And whenever the redefined method is called from any instance of the sub class then the new implementation comes into picture .The earlier implementation that already existed in the super class is shadowed by the new implementation.
