Java 1.1

serializable comparable

This subclass of java.lang.Number represents integers that can be arbitrarily large (i.e., integers that are not limited to the 64 bits available with the long data type). BigInteger defines methods that duplicate the functionality of the standard Java arithmetic and bit-manipulation operators. The compareTo( ) method compares two BigInteger objects and returns -1, 0, or 1 to indicate the result of the comparison. The gcd( ) , modPow( ) , modInverse( ) , and isProbablePrime( ) methods perform advanced operations and are used primarily in cryptographic and related algorithms.
