What is static method in ABAP?
- ABAP Keyword Documentation ? ABAP Glossary ? static method Methodof a classthat can be used independently of a class instance. Declared with CLASS METHODS. Static methods can only access static attributesand static eventsof their own class.
What is the difference between instance and static methods?
- We have the instance methods, to access and change the object state. On the other hand, we have the class methods, to access or change the class status. Then we have the static methods, which can neither change the class status, nor the object status.

Understanding the concepts of Object Oriented
Programming
What is Object Orientation?
In the past, information systems used to be defined primarily by their functionality: Data and functions were kept separate and linked together by means of input and output relations. The object-oriented approach, however, focuses on objects that represent abstract or concrete things of the real world. These objects are first defined by their character and their properties, which are represented by their internal structure and their attributes (data). The behavior of these objects is described by methods (functionality). Comparison between Procedural and Object Oriented ProgrammingFeatures Procedure Oriented
approachObject Oriented approach
Emphasis Emphasis on tasks Emphasis on things that does those tasks.Modularization Programs are divided into
smaller programs known as functionsPrograms are organized into
classes and objects and the functionalities are embedded into methods of a class.Data security Most of the functions
share global dataData can be hidden and
cannot be accessed by external sources.Extensibility Relatively more time
consuming to modify for extending existing functionality.New data and functions can
be easily added whenever necessaryObject Oriented Approach - key features
1. Better Programming Structure.
2. Real world entity can be modeled very well.
3. Stress on data security and access.
4. Reduction in code redundancy.
5. Data encapsulation and abstraction.
What are Objects and Classes?
Objects: An object is a section of source code that contains data and provides services. The data forms the attributes of the object. The services are known as methods (also known as operations or functions). They form a capsule which combines the character to the respective behavior. Objects should enable programmers to map a real problem and its proposed software solution on a one-to- one basis. Classes: Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.Local and Global Classes
As mentioned earlier a class is an abstract description of an object. Classes in ABAP Objects can be declared either globally or locally. Global Class: Global classes and interfaces are defined 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. All of the ABAP programs in an R/3 System can access the global classes Local Class: Local classes are define in an ABAP program (Transaction SE38) and can only be used in the program in which they are defined.Global Class Local Class
Accessed By Any program Only the program where it is defined. Stored In In the Class Repository Only in the program where it is defined. Created By Created using transaction SE24 Created using SE38 Namespace Must begin with Y or Z Can begin with any characterLocal Classes
Every class will have two sections.
(1) Definition. (2) Implementation Definition: This section is used to declare the components of the classes such as attributes, methods, events .They are enclosed in the ABAP statements CLASS ... ENDCLASS.CLASS DEFINITION.
ENDCLASS.
Implementation: This section of a class contains the implementation of all methods of the class. The implementation part of a local class is a processing block.CLASS IMPLEMENTATION.
ENDCLASS.
Structure of a Class
The following statements define the structure of a class:1. A class contains components
2. Each component is assigned to a visibility section
3. Classes implement methods
1. Components of a Class are as follow:
Attributes:- Any data,constants,types declared within a class form the attribute of the class. Methods:- Block of code, providing some functionality offered by the class. Can be compared to function modules. They can access all of the attributes of a class. Methods are defined in the definition part of a class and implement it in the implementation part using the following processing block:METHOD .
ENDMETHOD.
Methods are called using the CALL METHOD statement. Events:- A mechanism set within a class which can help a class to trigger methods of other class. Interfaces:- Interfaces are independent structures that you can implement in a class to extend the scope of that class.Instance and Static Components:
Instance components exist separately in each instance (object) of the class and Static components only exist once per class and are valid for all instances of the class. They are declared with the CLASS- keywords Static components can be used without even creating an instance of the class2. Visibility of Components
Each class component has a visibility. In ABAP Objects the whole class definition is separated into three visibility sections: PUBLIC, PROTECTED, and PRIVATE. Data declared in public section can be accessed by the class itself, by its subclasses as well as by other users outside the class. Data declared in the protected section can be accessed by the class itself, and also by its subclasses but not by external users outside the class. Data declared in the private section can be accessed by the class only, but not by its subclasses and by external users outside the class.CLASS DEFINITION.
PUBLIC SECTION.
PROTECTED SECTION.
PRIVATE SECTION.
ENDCLASS.
We shall see an example on Visibility of Components once we become familiar with attributes of ABAP Objects.The yellow block of code is CLASS Definition
The Green block of code is CLASS Implementation
The Grey block of code is for object creation. This object creation includes two steps: Step1 is Create a reference variable with reference to the class. Syntax: DATA :[PDF] instanet forms purchase and sale agreement
