Sybex CSG 17: Appendix: Answers To The Review Questions, Chapter 13 Concurrency, Question 4

I would also choose E. Line w4 as one of the correct alternatives because get() may throw two checked exceptions that we need to handle, InterruptedException and ExecutionException.

Mohamad,
Welcome to CodeRanch!,
While the method is allowed to throw exceptions under certain circumstances, I don't see anything that suggests they would in this example.

[Mohamad Almasri]

Thank you for welcoming me, Jeanne. I am glad to be part of this group.
I agree with what you said. The code might not throw any exception at all but if we go back to question 4, chapter 13 the question says:
Which lines need to be changed to make the code compile?
If I am correct the code will not compile because it fails to honor the Catch or Specify Requirement for checked exceptions. Line w4 must be enclosed by a try statement that catches the exceptions or we must provide a throws clause in order for it to compile.

I have attached a screenshot of the compilation error when I try to compile the code

[Jeanne Boyarsky]

I agree it can throw an exception. However, the code is not in a main method in the book. When not in a method, you have to assume the context is correct. In this case, that it handles the exception.
