The basic problem is that integers in computers have a finite range. For instance, the rage of a signed 16-bit integer is -32767 to 32767. What happens if arithmetic moves the value out of that range?

To ensure we end up with an unsigned 16-bit integer variable regardless of the underlying system, we’ll be using the C standard library’s type definitions from stdint.h.

Here's everything you need to know about Java operators and operator types, and how to use them to write expressions for your Java programs.
