Can you pass a `null` value to `Math.abs()` in Java?
Yes, `Math.abs()` can accept a `null` value for its argument if you're using the `Integer` or `Double` wrapper classes.
I'm a bit disappointed, as `Math.abs()` expects a primitive value and cannot handle `null` references.
Can you explain what would happen if you passed a `null` value of a wrapper class to a primitive method?
