OOPS Syntax

Hi All,

I am new on OOPS.

What is the difference between below syntax, when we use "->" and "=>"?

eg :lcl_airplane=>display_n_o_airplane( ).

and r_plane->set_attributes( im_name = 'AA New York'

im_planetype = '747-400' ).

Thanks in Advance.

Sujeet

hi Sujeet,

Instance methods are called using CALL METHOD <reference>-><instance_method>.

Static methods are called using CALL METHOD <classname>=><class_method>.

Static methods are addressed by class name, since they do not need instances.

Hi Sujeet,

'->' is used to call a instance method, in this case you have to create the instance of the class object. If you create a local class, methods created using the key word 'METHODS' will be called using '->'

'=>' is used to call a static method, in this case you do not have to create the instance of the class object. If you create a local class, methods created using key word 'CLASS-METHODS' will be called using '=>'.

George
