Hi,

Latest ABAP consists of (from 4.7Version onwards) this classes and Interfaces and objects, which are part of Java/OOP's concepts.

In ABAP we create these Classes and Interfaces from T Code SE24

we define methods like subroutines and write the code to do.

Go through the SAP doc for further details.

Hi,

Classes are templates for objects. Conversely, you can say that the type of an object is the same as its class.

components of the class describe the state and behavior of objects.

Local and Global Classes: Classes in ABAP Objects can be declared either globally or locally. You define global classes and interfaces in the Class Builder (Transaction SE24) in the ABAP Workbench. They are stored centrally in class pools in the class library in the R/3 Repository.

A complete class definition consists of a declaration part and, if required, an implementation part.

The declaration part of a class <class>

CLASS <class> DEFINITION. ... ENDCLASS.

It contains the declaration for all components (attributes, methods, events) of the class.

The declaration part belongs to the global program data.

If you declare methods in the declaration part of a class, you must also write an implementation part for it. This consists of a further statement block:

CLASS <class> IMPLEMENTATION. ... ENDCLASS

The implementation part of a local class is a processing block. Subsequent coding that is not itself part of a processing block is therefore not accessible.

Interfaces are independent structures that you can implement in a class to extend the scope of that class.

a universal point of contact.

They provide one of the pillars of polymorphism, since they allow a single method within an interface to behave differently in different classes.

Global & Local Interfaces

The definition of a local interface <intf> is enclosed in the statements:

INTERFACE <intf>.

...

ENDINTERFACE.

The definition contains the declaration for all components (attributes, methods, events) of the interface.

They automatically belong to the public section of the class in which the interface is implemented.

Can be declared globally or locally within a program.

Locally declared in the global portion of a program using:-

INTERFACE <intf>.

...

ENDINTERFACE.

The definition contains the declaration for all components (attributes, methods, events) of the interface.

Interfaces are included in the public section of a class.

Interfaces do not have an implementation part, since their methods are implemented in the class that implements the interface.

hi,

As in function group we will have

data variables declared in top,

functions....< function ...end function>

simillarly in class..

data variables are called as Attributes,

Functions as Methods..<method....end method>

methods are services provided to objects.

events are raised at their definition ...Raise event

...this will trigger a method which was defined .

Naresh.
