Thanks for your knowledge sharing sir. Can you please tell me which to use when?. How to decide which one we should go for static or instance?

[@sapabapbyrahulmehta]

Hello - Please refer to the below mentioned link. It is an excellent link. Requesting you to please refer after creating the programs using instance and static methods. It will help you to understand better. www.linkedin.com/posts/activity-7263424466313981952-gBir/?

Hello sir i have a doubt 1. what is the difference between data x type i and data x type reference ??? 2.Why reference variable is created while creating the object ?? Plz explain me 3. Why class is called user defined datatype is it not similar to subroutine pool or function group ??

[@sapabapbyrahulmehta]

Below are the answers. 1) Suppose I am writing - DATA : LO_OBJECT TYPE REF TO ZCLASS, it means LO_OBJECT is a object reference variable to ZCLASS. REFERENCE itself is saying - it will act as a pointer or reference to the class. When we compare to TYPE , suppose I am writing - DATA : LV_DATA TYPE I. It does not mean that LV_DATA is a reference or pointer variable. 2) Compare it to real world - You are passing your user name and password, Captcha always comes at run time. You are doing a transaction, OTP always comes at runtime. If OTP/Captcha is incorrect, transaction will not happen. Same is here, you are creating a object at runtime and that is calling our class methods, attributes etc. Security/data hiding is there that's why OOPS is preferable as everything happens at runtime with the help of object. 3) Yes, class is a user defined data type as we are creating a template having methods, attributes etc. and accessing that template with the help of object, same thing is with data type - data types are like templates which is used to declare n number of objects. So class is a user defined data type. Function group is a container for function modules which is only a container and you can not access through DATA statement, same is with Subroutine pool, so a class can not be compared to function group and subroutine pool.

[@sayanroy6181]

Hello sir, your videos are really helpful for me. But I have one doubt: During global class creation from SE11, there is one option named 'Instantiation' which has public, private, protected and abstract options. What is the provision or usability of the first three options. Like I know if we make this as private then we cannot access this class. Then why SAP has given these options while we already have options to make the methods and attributes as public, private or protected. Can you please be brief about it..

[@sapabapbyrahulmehta]

Hello Sayan - Once you move forward in the same playlist, you will get the answer of these questions automatically. Suppose - When you will earn ALV by CL_SALV_TABE, this class instantiation is private, so we can not create the object outside the class using CREATE OBJECT statement, but we will use a static method Factory to return the static object and with the help of that we will call the public methods of the class.
