What ABAP statements can you use to create an instance of the class CL_GUI_CUSTOM_CONTAINER?

The correct approach to creating an instance of the class CL_GUI_CUSTOM_CONTAINER is to declare a reference variable for the class and then use the CREATE OBJECT statement to instantiate the object.

When you declare DATA: go_container TYPE REF TO CL_GUI_CUSTOM_CONTAINER, you are establishing a reference to the class rather than the class instance itself. This is crucial in ABAP for handling object-oriented programming, as instances of classes in ABAP are created via reference variables.

The CREATE OBJECT statement is then used to create an instance of CL_GUI_CUSTOM_CONTAINER and assign it to the reference variable, enabling you to work with that instance of the class effectively. This method allows for dynamic memory management and ensures that you can access the properties and methods associated with the class through the reference.

In contrast, using DATA: go_container TYPE CL_GUI_CUSTOM_CONTAINER followed by CREATE DATA or CREATE OBJECT would improperly handle the class instantiation. The CREATE DATA variant is primarily used for creating data references rather than class instances, and while CREATE OBJECT could be syntactically correct, it wouldn't be valid without a reference type declaration beforehand. Thus, the method selected (using a reference type with CREATE OBJECT) accurately adheres to the principles of object-oriented programming in ABAP.
