Free Java objects in RPG

Hi,
 
 I'm a little confused about freeing java objects created within RPG.
 
 Rpg ref v5r2 says that if we code:
 
>  string = createString(myString);
>  string = trimString(string);
 
 we actually have 2 java objects to free and suggests how to correct the
code.
 
However suppose we have coded something like this:
 
>  for i = 1 to 100;
>    string = createString(myString);
>    newObject = someMethod(string);
>    . . . .
>  endfor;
 
 At the end of the loop:
 
> FreeLocalRef(String);
> FreeLocalRef(newObject);
 
 should be enough ?
 
 Or we have 200 objects to free ?
 
 Thanks.
Beppe.
