What is the correct code to call a public static method called my_method from my_class?

The correct choice for calling a public static method from a class in ABAP is the first option. In ABAP, static methods are invoked using the double arrow operator =>, which indicates that the method belongs to the class itself rather than an instance of the class.

When you use my_class=>my_method( ), you are correctly specifying that you want to call the static method my_method from the class my_class. The parentheses are necessary to indicate that you are invoking the method; this syntax is standard for calling static methods in ABAP.

Other options do not conform to this syntax: using a single arrow operator implies an instance method call, which requires an instance of the class to be created first, thus making it invalid for static methods. Additionally, omitting the parentheses entirely, as seen in the third choice, does not properly execute the method as it does not indicate a method invocation.
