How long data type can i get in jave ? In c/c++ we get max 64 bit in jave is it possible to use 256 bit or more ?

First Google hit -
http://java.sun.com/docs/books/tutorial ... types.html

There's also java.math.* which provides arbitrary-precision integers and decimals, but they're currently not supported at this online judge.

For primitive data types the max you can go in Java is 64 bits for a long (which is 32 bits for C/C++).

There are other types such as BigInteger, BigDecimal, to name a few.

Hi folks,

Actually, since java.math.BigInteger is not supported by the online judge, one is supposed to implement the arbitrary precision long numbers by itself, right ?

Thanks,

Yes.
Or you can wait until the new server (with full Java 5 support) will finally be ready...
