INTERFACE
1. Interfaces are
independent structure which is used in a class to extend the functionality of a
class.
2. It contains
collection of methods without any implementation.
3. Where as a class
contains methods with implementation.
4. We need to
specify an interface with the required method
names in SE24 TCODE.
5. Now, this
interface can be used by ‘n’ no of classes to extend the functionality of the
class.
6. Just give the
name of interface under the ‘interface’ tab.
7. All the
interface methods will be automatically copied to the classes in a particular
class without affecting the other classes.
Polymorphism
Polymorphism
is a concept by which the same method names will behave differently in
different classes i.e. each method will have its own implementation in
different classes but with the same name.
EXAMPLE ON INTERFACE
•
Go to SE24 provide interface name.
•
Interface name should start with ZIF.
•
Define
the method name.
•
Provide
Parameters
•
Save
it and activate it.
•
We cannot implement
the method of this interface.
•
Provide the name in
the class Tcode SE24.
9. SAVE IT..
10. Now go to
Methods Tab then we can see the interface method in the class method.
