What does this mean?

An exception is any error or unexpected behavior encountered by an executing program. Exceptions can be thrown because of a fault in your code or in code that you call (such as a shared library), unavailable operating system resources, unexpected conditions that the runtime encounters (such as code that can’t be verified), and so on.
