ConstructorSummary
BigInteger(byte[] val)Translates a byte array containing the two's-complement binary representation of a BigInteger into a BigInteger.
BigInteger(int signum, byte[] magnitude)Translates the sign-magnitude representation of a BigInteger into a BigInteger.
BigInteger(int bitLength, int certainty, Random rnd)Creates a randomly generated positive BigInteger that is probably prime, with the specified bitLength.
BigInteger(int numBits, Random rnd)Creates a randomly generated BigInteger, uniformly distributed over the range 0 to (2numBits - 1), inclusive.
BigInteger(String val)Translates the decimal String representation of a BigInteger into a BigInteger.
BigInteger(String val, int radix)Translates the String representation of a BigInteger in the specified radix into a BigInteger.
