it would depend on how/if the class needs to be instaniated. If it has static methods you can call them straight way.





    CALL METHOD cl_gui_frontend_services=>gui_upload
      EXPORTING
        filename                = lv_file
        filetype                = 'BIN'
*     has_field_separator     = SPACE
    IMPORTING
      filelength              = lv_file_length
      CHANGING
        data_tab                = lt_data
      EXCEPTIONS
        OTHERS                  = 19.

but if the method is an instance method, you would first have to create an object of the class, then call the method.



  DATA: gr_zip TYPE REF TO cl_abap_gzip.

  CREATE OBJECT gr_zip.
  call method  gr_zip->compress_binary(
                EXPORTING
                       raw_in = raw_in
                IMPORTING
                       gzip_out = zip_out ).

Hello

If you display the class using either transaction SE80 or SE24 then you can run the class in test-mode. If instantiation is public then you can create an instance and call any of its public methods.
