Task: Pass tests.PointBounds.
Instead of throwing an exception when one of the int fields of Point is set to a negative value, write an aspect to trim the value to zero.
around advice; note that inside the body of an around advice, you can invoke a proceed statement with (possibly different) join point parameters.
Your aspect is going to look like this:
public aspect Answer4 {
void around(int val): <pointcut> {
<if necessary, sanitize val>
proceed(val);
}
}
With a correct implementation, you should pass tests.PointBounds.
When done, remove your aspect from the build path and continue with Exercise 5.
