Static Method to calculate ' Average '.

[Former Member]

Hi

I am wondering which one is preferred?  Static or Instance methods for calculating 'average' (e.g average sales).

My class lcl_company is having attributes name and sales. which represents name = name of the company, sales = total sales of one company under department: automobiles.

eg output:

Department: automobiles.

name = abc company

sales = 1000

name = xyz company

sales = 2000

total companies added: 2.

now i want to calculate the average sales of the companies under department automobiles.

I prefer using a static method (is it good choice), if not, why instance method. while using the static method, I noticed that i need to stick just with the defined attributes.

Please advice on calculating average.

Thank you.

Hi Pawan,

You`d better declare a another object, say 'Accountant', in this object, have a method used to calculating average, which importing parameters is a itab. In this itab, havd appended this two companies. I think no mater this calculating average method is static or instance, it`s ok, that`s depened on you how to abstract 'Accountant'.

BTW, static method has a small memory footprint than instance .

Hi Pawan,

There are so many ways,:

One, as you said, you defined this itab as a attribute of this Object, then you need define another attribute 'AverNum' as public. Of cause, this Object have a method using to calculate the average number, passing the value to public attribute 'AverNum', then you can access this public attribute from outside.

Another way:  Define this itab as a importing parameter of your average method, same time, this average method have a return parameter. Then you can call this static object method or instance object method from outside, and return your output by return parameter.
