hi,
I have a strong feeling that it cannot be done but am not sure.
Since in Java, it's pass by value, i feel it cannot be done.
Yeah array is definitely a solution but i'm just looking for a simple java equivalent of C code where u pass the "pointers" and swap it.

> AnyObjectType temp[] = swap(a,b) ;
> a = temp[0] ; a = temp[1] ;
