Note quite understand what you mean on this ==> you should avoid to do
questions different from java-as400 environment
in this list.

Hi Hockchai,

you should avoid to do questions different from java-as400 environment
in this list.

Read about immutable objects[1]. Briefly, unless your param be
immutable, every change done over the object, it will be made
effective in the whole scope of the variable, so, you don't need
return the value.

use public void execute(MyObject parm1);

If I have a method that accept an object as parameter and the main purpose
of this method is to call a backend api and update/add more info into the
object in the parm. In this case, should I directly update that object in
the parm and return void or should I return a object that is the same as
the
parm?

public void execute(MyObject parm1);

or

public MyObject execute(MyObject parm1);
