Throw statement equivalent in ABAP Objects

Question

Hi All,
I am trying to raise an exception and use a throw statement after catch inside try endtry in ABAP objects. Later i understood that there is no throw statement defined in ABAP objects. Could anyone help me out to understand the equivalent throw statement in ABAP and how to use in raise exception. I am pasting my code below for reference.
try.
    CATCH Zxx_EXCEPTION into err.
     write:/ err->local_text.
    message err->LOCAL_TEXT type 'I'.
     if err->local_text = ZIF_XXXX~BUSOBJLOCKED.
      throw CX_AI_APPLICATION_FAULT.
endtry.
Thanks

Hello Deno
The TRY/CATCH logic of ABAP-OO is pretty much the same like in Java. Instead of throwing exception we have to raise them.
Method execute somewhere raise an exception of class zcx_myexception.
method execute.
  if ( condition = abap_true ).
  else.
    RAISE EXCEPTION TYPE zcx_myexception
      EXPORTING
        textid = ...
        <parameter> = ...
  endif.
endmethod.
TRY.
  call method go->execute( ).
  CATCH zcx_myexception INTO lo_error.
* Do error handling
ENDTRY.
If the method that calls go->execute does not surround the method call by TRY/CATCH then it must define the exception class in its interface and, thereby, propagate the exception to the next higher level calling method.
