我如何从abap的内部表中计算所有员工的平均工资？

Question

I created a class that has the attributes (name ,address ,age ,salary). I created employee objects in an internal table defined as follows

 Data itab_employees  TYPE TABLE OF REF TO lcl_employee.

Is it possible to create a method that calculates the average of the salaries of the employee objects that are inside internal table (itab_employees)?

This what i tried so far

METHOD get_avg_salary.
DATA: r_employee  TYPE REF TO lcl_employee,
      getsalary   TYPE i,
      average     TYPE i,
      sum_salary  TYPE i,
      no_employee TYPE i.

getsalary = r_employee->get_salary( ).
no_employee = lcl_employee=>get_n_o_employee( ).

LOOP AT it_employees INTO r_employee.
  AT LAST.
    SUM .
    sum_salary = getsalary.
    average    =  sum_salary / no_employee.
  ENDAT.
ENDLOOP.
re_avg_salary = average.
ENDMETHOD.

But i am not sure about the line getsalary = r_employee->get_salary( ).

Thanks for your comments @gkubed. I figured something out which worked out for me

  METHOD get_avg_salary.
DATA: r_employee  TYPE REF TO lcl_employee,
      average     TYPE i,
      sum_salary  TYPE i.

LOOP AT it_employees INTO r_employee.
    sum_salary =  sum_salary +  r_employee->get_salary( ).
ENDLOOP.
average    =  sum_salary / sy-tfill.
re_avg_salary = average.
ENDMETHOD.
