Wrapper class ??

In Java, primitive types have associated wrapper classes,

like primitive type int VS Integer class etc,

But can I use objects of wrapper class to do operations of mathematics??

Or I should convert wrapper class to primitive type ???

Another question is about n! .When I write codes for practice,the result

of 5000! is too big. Should I use class*BigDecimal* or *BigInteger* in *java.math* package??

I need your help.

Thankx your help in advanced.

No.

Yes.

Note that others have implemented their own "wrapper" classes which do provide methods for various mathematical operations.

Yes, you could do that.

What others?

Would you tell me some examples ??
