Explain the difference between instance and static constructors in ABAP: instance uses constructor with importing parameters; static uses class underscore constructor with no parameters and runs once per class.
In this session you will learn how to convert a local class to global class
Explore how ABAP methods return multiple exporting parameters in both class methods and global classes, distinguishing mandatory versus optional parameters, and implementing a get customer example.
Explore global inheritance in ABAP by building a vehicle, cycle, and bike hierarchy, overriding methods with the super keyword to extend behavior and add attributes.
Learn to handle standard exceptions by defining an exception class, raising and catching it with a catch block, and displaying user-friendly, standard messages captured from the system.
Learn how exceptions arise as runtime errors, why unhandled exceptions terminate programs, and how to handle them with try and catch blocks, guarding risky code like division by zero.
Master oops alv in sap abap by using salv classes to instantiate standard classes with a factory, access components, and render data in reports.
Develop an interactive alv report using salv classes to display customer data from a selection screen, then convert the kuna column into a hotspot for navigation.
We are best in providing material and documentation for all concepts including sample programs along with coding part.
Object Oriented ABAP is a mandatory skill for every ABAPer, for every latest technology like ABAP On HANA, ODATA, Webdynpro , Workflow etc OOPS ABAP is a main prerequisite. Sustaining without OOPS knowledge is difficult for any ABAPer. Now a days all clients/companies are preferring to develop their projects in object oriented approach. Object orientation simplifies software design to make it easier to understand, maintain, and reuse. Object Oriented Programming (OOP) represents a different way of thinking in writing software. The beauty of OOP lies in its simplicity.
Provide properties like data hiding(encapsulation) & code reusability(inheritance) with more data security. Better performance with less consumption of time. Helps in future orientation. Simple and it much easier to maintain as compare to procedural ABAP programming. OOPS language allows to break the program into the bit-sized problems that can be solved easily (one object at a time). The new technology promises greater programmer productivity, better quality of software and lesser maintenance cost. OOPS systems can be easily upgraded from small to large systems.
Advantages of OOPS Concept in ABAP:
In OOABAP, programs are divided into objects leading to better and powerful data management.
Provide properties like data hiding(encapsulation) & code reusability(inheritance) with more data security.
Better performance with less consumption of time.
Helps in future orientation.
Simple and it much easier to maintain as compare to procedural ABAP programming.
Relatively flexible & adaptable to changing business needs.
Object Oriented programming languages include features such as “Class”, “Instance”, “Inheritance” and “Polymorphism” that increase the power and flexibility of an object.
