1. Create the instance of the class.

CREATE OBJECT C1. (If there are any parameters to the constructor of the method you will have to pass here.

2. Now call the method

CALL METHOD C1-->METHOD1. (Pass the parameters).

You can do this using the pattern of the ABAP Editor also.

If its a static class, you can directly call the method without instantiating the class

Ravi

Hi,

You need to create a instance of the class and call the method using the syntax CALL METHOD instance_name->method_name if the method is an instance method.

For static methods you need to use the syntax CALL METHOD class_name=>method_name

Hi sivaprakash pandian ,

If u want to call the method of same class in the mplementation of another method,just u need to use CALL METHOD METHOD_NAME, other wise if u want to call the method of other class, u have create the object of that class and with that obj, uneed to call the method,

i.e,

CREATE OBJECT OBJ.

CALL METHOD OBJ->METH1.

Hi Siva,

Check the ABAPDOCU transaction. And go through this program....

REPORT demo_class_counter .

CLASS counter DEFINITION.

PUBLIC SECTION.

METHODS: set IMPORTING value(set_value) TYPE i,

increment,

get EXPORTING value(get_value) TYPE i.

PRIVATE SECTION.

DATA count TYPE i.

ENDCLASS.

CLASS counter IMPLEMENTATION.

METHOD set.

count = set_value.

ENDMETHOD.

METHOD increment.

ADD 1 TO count.

ENDMETHOD.

METHOD get.

get_value = count.

ENDMETHOD.

ENDCLASS.

DATA number TYPE i VALUE 5.

DATA cnt TYPE REF TO counter.

START-OF-SELECTION.

CREATE OBJECT cnt.

CALL METHOD cnt->set EXPORTING set_value = number.

DO 3 TIMES.

CALL METHOD cnt->increment.

ENDDO.

CALL METHOD cnt->get IMPORTING get_value = number.

WRITE number.

Hope it helps u in some way.
