You are a project manager at a software company and you have to assign tasks to your team members. You have three tasks: A, B and C. Task A requires 10 hours of work and has a deadline of tomorrow. Task B requires 5 hours of work and has a deadline of next week. Task C requires 15 hours of work and has a deadline of next month. You have two team members: X and Y. X can work 8 hours per day and Y can work 6 hours per day. How would you assign the tasks to your team members to meet the deadlines and optimize the productivity?

Look at this Hibernate code. Assume there is one to many mapping between the User and Address object.

Line 1:

Session session = sessions.openSession();

Line 28:0

Transaction tx = s s.beginTransaction();

Line 3:

User u = (User) session.createQuery("from User u where u.name= .setString("userName", userName).uniqueResult();

Line 4:

Map address is = u u.getAddress();

Line 5:

Line 6:

session.close();

tx.commit();
Line 6:

close () ;

Line 7 : Integer 2inco * de = (Integer) address.get("zipcode");

What would happen on Line 7?

ClassCast exception as address.get("zipcode") would return Collection.

Hibernate Session will throw an exception because the results are fetched from lazy association outside the hibernate session.

Hibernate Session will throw an exception that can't be fixed by specifying lazy="false" for the association mapping.

No exception would be thrown.

Asked about the how was the test? Was I were able to solve the questions? Were I got struck anywhere and why?
