Hi Madhu,

1.ABAP Objects is a complete set of object-oriented statements that has been introduced into the ABAP language...

2. SAP Business Objects and GUI objects - already object-oriented themselves - will also profit from being incorporated in ABAP Objects..

have a look at this

Hi Madhu,

There are lots of resources available on SDN in this topic.

The best one to read is <b>ABAP OBJECTS by Horst Keller</b>.

Template for calling a class

• Create reference to class lcl_airplane

DATA: airplane1 TYPE REF TO lcl_airplane.

• Create instance using parameters in the cosntructor method

CREATE OBJECT airplane1 exporting im_name = 'Hansemand'

im_planetype = 'Boing 747'.

• Calling a method with parameters

CALL METHOD: airplane1->display_n_o_airplanes,

airplane1->display_attributes.

Interfaces

In ABAP interfaces are implemented in addition to, and independently of classes. An interface only has a declaration part,

and do not have visibility sections. Components (Attributes, methods, constants, types) can be defined the same way as in classes.

· Interfaces are listed in the definition part lof the class, and must always be in the PUBLIC SECTION.

· Operations defined in the interface atre impemented as methods of the class. All methods of the interface

must be present in the implementation part of the class.

· Attributes, events, constants and types defined in the interface are automatically available to the class

carrying out the implementation.

· Interface components are addressed in the class by ]
