Hi,
You can probably not use the hashCode method to get unique numbers.
>From the documentation of Object.hashCode():
"It is not required that if two objects are unequal according to the
equals(java.lang.Object) method, then calling the hashCode method on each of
the two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results for
unequal objects may improve the performance of hashtables. "
So two objects which aren't equal can produce the same hash code.
"Normal" hashCode implementations usually creates well distributed hash
codes, but not unique ones.
