Sap Abap Objects Online Training Study For Sap Certification

ABAP Objects Syntax Overview Preview 10:20

In this lecture you will see the syntax of defining local classes, its attributes and methods.

Creating Your First ABAP Objects Class Preview 10:08

In this lecture we are creating our first local ABAP class, putting all theory which we haved learned in the previous lectures into practice.

Encapsulation in Object-oriented Programming using Getter and Setter Methods Preview 16:43

First we're going to learn some techniques to protect the integrity of an object. Then we will see how to create functional methods (Getter/Setter).

Types of Parameters: Pass by Reference vs. by Value Preview 04:04

We already saw that there are different types of parameters. Here we will have a detailed look at how parameters are passed from the calling programm to the called method.

Declaration and Instantiation of Objects and the Class Constructor Preview 09:44

After looking at the definition of classes, now let's see how to create and use objects, which are bases on these class definitions.

In addition, the constructor-method is considered.

Working with Objects and Components Preview 18:01

Here you will see how to access the object instances and its components, like attributes and methods.

Types of Method-Calls and the Null-Object-Reference Preview 17:11

First we will see how to define user-specific data types within a class.

Then we will create some new methods in our employee-class to see what you have to consider while defining and calling methods.

At the end I'm going to show you a frequent mistake, called "Null Object Reference", what occurs at wrong calling of a method.

Events in Object-oriented Programming Preview 08:12

After learning how to work with objects, how to do some method-calls and other important things, we're going to work with events and eventhandlers as well.

Getting Started with the SAP Class Builder Preview 18:38

After working with local classes, in the coming sections we will work with global classes. This lecture in an introduction to the class builder, which is the tool in SAP to create global classes.

Class Builder: Attributes, Events and Types Preview 13:23

In this lecture we will have a look at how to define a gloabal class, its components, like attributes, methods, events and types, in the class builder.

Class Builder: Methods Preview 17:06

This lecture shows you how to define methods in the class builder and what you have to bear in mind while doing this.

Class Builder: Generating Method Call Code with the Pattern Wizard Preview 08:37

Here we will use the pattern functionally to let the system generate the coding for calling a method.

Inheritance: Creating a Subclass Preview 13:17

In this lecture we will talk about inheritance and create our first subclass.

Inheritance: Redefinition Preview 15:26

An important tool of inheritance is the redifintion of methods. In this lecture we will have a detailed look at it and see how the redefine methods in the class builder.

Inheritance: Instantiate Subclass Preview 06:05

Here we will have some practical exercises to truly unterstand the inheritance concept.

Inheritance: Class Constructor Preview 04:24

Here we will get to know the class constructor of an class and see when it is called.

Inheritance: Abstract Classes and Methods Preview 05:12

This lecture informs about abstract classes and methods.

Inheritance vs. Composition: Pros and Cons Preview 18:15

Inheritance is an powerful technique in the object-oriented programming - see what it is and learn how to use it to build powerful and robust appliacations.

Introduction to Polymorphism: Casting Preview 09:42

See how you can use polymorphism to create highly flexible designs. 

Polymorphism: Narrowing and Widening Cast Preview 07:56

Casting is sometimes necessary in order to create some flexible designs. We will have a look at how to work with object reference variables in a generic way.

Polymorphism: Dynamic Binding Preview 11:58

Dynamic binding is a powerful technique to work with object references also in a generic way. See how it works!

Interfaces Preview 07:57

Here we will talk about whar interfaces are and how we can take advantages of this. We'll also have a look at the system and see how to create global interfaces in the class builder.

Friends Preview 02:46

In ABAP Objects are some friendship-relationships between classes possible. This lecture informs you about and shows a practical example.

Exception Classes: Overview Preview 07:35

Exception handling is as important as the main application logic. In this lecture we will see how you can use exception classes for handling of errors and exceptions in your programs. 

Exception Classes: Declaration Preview 15:01

In this lecture we will see how to create an exception class.

Exception Classes: Raising and Catching Exceptions Part 1 Preview 09:15

Here you will see how to raise exceptions.

Exception Classes: Raising and Catching Exceptions Part 2 Preview 14:22

Here you will see how to catch exceptions.

Unit Testing with ABAP Unit Preview 06:30

ABAP Unit is an testing tool in SAP which can be used to do some moduletests. In this lecture we will have a detailed look at that.

Persistent Classes Preview 20:40

Here we will get the persistent service of the object services to know. Based at our employee-exercise, we will see what persistent classes are, and how to use it.

How To Debug Objects Preview 07:59

An really important topic, especially in the daily business, is how to debug objects and get all necessary information about your objects in the debugger.
