ABAP INTERFACES in Objects

INTERFACES statement is used in ABAP Objects programming development. We can declare interfaces globally or locally in our ABAP programs. Interface will contain only declaration parts; it won’t contain any executable statements. We can declare all the components like attributes, methods, types etc in an Interface. In the definition part of a Class the declared interfaces will be listed. In the methods of class, all the operations in interfaces will be defined and it should present in the class implementation part.

All the declared components will be available automatically in the class.
