ABAP methods overloading

Question

Hi All,
In ABAP objects, is it possible to use same method name with different signature
in the same class. In Se24, i have build a class xyz and a method A. The method A has a string as importing parameter. I have to use the same method A with an internal table as importing parameter. Any code samples and replies would be really appreciated.
Thanks,
Ricky

In abap objects overloding(we can change the signature ) is possible only with construcor.
It is not possible with methods and the signatures can not be changed.
