Throw exception on numeric overflow [duplicate]

Question

Is it possible to throw some sort of runtime exception when integer overflow occurs rather then failing silently. For e.g.

int x = 100000000 * 1000000000;

print 1569325056 due to overflow and what I w'd like is to get some sort of runtime exception

Answer 1

Yes, Starting from Java-8 you can use the new Exact method, it will throw an exception(java.lang.ArithmeticException: integer overflow) on overflow. E.g.

Math.multiplyExact(100000000, 1000000000);
