I'm new to java (like a few weeks new), but coming from a C++ background..

This is going to sound retarded, but... can someone explain to me how I can make a BigInteger object to make it have the same value as another BigInteger object? That is they have to have the same value but be two different objects.. like a copy-constructor maybe??

And if I can't, due to the fact that java frowns on copy constructors, then why am I able to half-assedly get around this by doing something like
BigInteger foo = bar.add(BigInteger.ZERO);
where bar is another BigInteger

Thanks a lot, I've been able to find no info besides implementing Cloneable for my own classes.. this all seems really weird to me..

Just wondering... why do you want to do this? The BigInteger class is immutable, so two instances sharing memory will never be a problem.
