Re: java best pratice

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);
