 ### Basic Example
 Every abap2UI5 app is an implementation of the `Z2UI5_IF_APP` interface. Create a new class with the following code:
 ```abap
-CLASS z2ui5_cl_app_hello_world DEFINITION PUBLIC.
+CLASS z2ui5_cl_app_hello_world DEFINITION PUBLIC CREATE PUBLIC.
 
   PUBLIC SECTION.

 ::: tip **ABAP Language Versions**
 While we need to distinguish between Standard ABAP and ABAP for Cloud in the HTTP Handler, the apps themselves are independent. You can decide whether to develop your apps compatible with ABAP Cloud or not.
