How do we create/use pointers in fantom???

Fantom does not support C-style pointers.

thanks that's what we thought is there something instead??

Does that not depend on what you want to do / achieve?

Every variable (be it a parameter, field, or local variable) is a reference to an object. And that is pretty much what everything is. Fantom uses immutable types much more than Java, so often times you can't change any of the fields of an object. Instead you create a new instance and update what your variable references.

Under the covers there is an optimization for references to an Int, Float, or Bool. But that isn't really exposed like it in Java.
