I have done simple oops program. the program is below

class class definition . It is throwing error Method *** is unknown or protected or private.

PUBLIC SECTION.

DATA : WTEXT(40) VALUE 'ABAP OBJECTS'.

METHODS:DISPLAY.

ENDCLASS.

&----

class c1 IMPLEMENTATION

&----

CLASS Class IMPLEMENTATION.

METHOD DISPLAY.

WRITE:/ ' THIS METHOD TO DISPLAY'.

ENDMETHOD.

ENDCLASS.

*********************

START-OF-SELECTION.

DATA: CLASS TYPE REF TO class.

CREATE OBJECT: CLASS.

*WRITE:/ CLASS->WTEXT.

call method:

CLASS-> DISPLAY.

It is throwing error Method *** is unknown or protected or private.

Please rectify the error.

call method:CLASS-> DISPLAY.


class class definition .
  PUBLIC SECTION.
  DATA : WTEXT(40) VALUE 'ABAP OBJECTS'.
  METHODS:DISPLAY.
ENDCLASS.


CLASS Class IMPLEMENTATION.
  METHOD DISPLAY.
    WRITE:/ ' THIS METHOD TO DISPLAY'.
  ENDMETHOD.
ENDCLASS.

CREATE OBJECT: CLASS.
