Lesson 30 - Data Types - wraparound part 4 - Writing your own method on Overflow

As we saw in the last lesson, if we want a RuntimeException
on overflow instead of the values wrapping around
we can make use of the Math.xxxExact methods introduced in
Java 8.
If we type Math.addExact tab x2 and we can see there are two
overridden methods one returning an int and the other a long

Now what if we want to use the byte or short, but want
an exception at Runtime on overflow?

Welcome to lesson 30, part four .
