Using BigInteger Multiply operator

Question

Hello, I was wondering if there was a way to multiply BigInteger variables together, because the * operator cannot be applied to BigInteger.

So I was wondering if it was possible to multiply two BigIntegers together without using the * operator.

Answer 1

You use BigIntegers multiply() method like so:

BigInteger int1 = new BigInteger("131224324234234234234313");
BigInteger int2 = new BigInteger("13345663456346435648234313");
BigInteger result =  int1.multiply(BigInteger int2) 

Answer 2

You can use the multiply(BigInteger) method in BigInteger. So:

BigInteger result = someBigInt.multiply(anotherBigInt);
