Java EE 7 Application Developer — Question 27

Your web application requires logic to remember items that a user placed into a shopping cart.
Which two mechanisms should you use to associate that information with the user? (Choose two.)

Answer options

• A. HttpServletResponse objects
• B. ServletContext objects
• C. HttpSession objects
• D. a database

Correct answer: B, C

Explanation

The correct answers are B and C because ServletContext objects allow shared data across servlets and users, while HttpSession objects are specifically designed to maintain user-specific data during a session. HttpServletResponse objects are used for sending responses to the client, and a database is not directly used for session management in this context.
