can static methods /attributes be called from instance?

CLASS lcl_course DEFINITION.

PUBLIC SECTION.

METHODS: get_course_name IMPORTING im_name type string.

CLASS-METHODS: list_prices_and_discounts.

ENDCLASS.

CLASS lcl_course IMPLEMENTATION.

METHOD get_course_name.

ENDMETHOD.

METHOD list_prices_and_discounts.

ENDMETHOD.

ENDCLASS.

Data: course1 type ref to lcl_course,

course2 type ref to lcl_course.

Start-of-selection.

Create object course1.

call method course1->list_prices_and_discounts(). """""""" would this call be considered right??

All i want to know is , can we call the static attributes/methods of a class from the instance??...

Is it required that we should only call static attributes with Class names in our program??

should i only use lcl_course=>list_prices_and_discounts().

it is possible in case of static attr/methods like instance variables/methods we can call using instance.

Why don't you simply try it? If list_prices_and_discounts() on it's own works, then fine. If not then you know you must use the class name.

As a matter of good programming style, I always use the class name, even in static methods, as then it is clear what is going on, that the method or attribute is static. Similarly in instance methods, I always use me-> when referencing other instance methods or attributes,

I reaaly don't understand why this kind of question is asked. Are you afraid that if you use the wrong syntax you'll break the system or something?
