The java.math.BigInteger.xor(BigInteger val) returns a BigInteger whose value is (this ^ val). This method returns a negative BigInteger if and only if exactly one of this and val are negative. Here, “val” is the value to be XOR'ed with this BigInteger.Firstly, create two BigInteger objects −one = new BigInteger("6"); two ... Read More

BigInteger class is used for big integer calculations which are outside the limit of the primitive data types. It provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.Firstly, set a long value −Long l = 198L;Now, create a new object ...
