Which of the following is a result type in Struts 2?
a) Action
b) Interceptor
c) Result
d) Filter
Answer: c) Result
Explanation: In Struts 2, a result is a predefined or custom class that encapsulates the view to be rendered as a response to a user’s request. It defines how the action’s output will be presented to the user, such as a JSP page, a JSON response, or a PDF document.
What is an action in Struts 2?
a) A Java class that implements the business logic
b) A configuration file that defines the application’s behavior
c) A template for generating views
d) A container for managing components
Answer: a) A Java class that implements the business logic
Explanation: In Struts 2, an action is a Java class that implements the business logic of a web application. It receives user input from the web layer, performs the necessary processing, and prepares the response to be rendered by the view layer.
What is an interceptor in Struts 2?
a) A configuration file that defines the application’s behavior
b) A Java class that implements the business logic
c) A template for generating views
d) A component that intercepts requests and responses
Answer: d) A component that intercepts requests and responses

What is the purpose of an interceptor stack in Struts 2?
a) To define the order of execution for interceptors
b) To define the result type for an action
c) To define the business logic for an action
d) To define the view for an action
Answer: a) To define the order of execution for interceptors
Explanation: An interceptor stack in Struts 2 is used to define the order in which the interceptors should be executed for a particular action. Interceptors are applied in a sequential order as defined in the stack, allowing developers to control the flow of request processing and apply cross-cutting concerns in a specific order.
What is the purpose of a result type in Struts 2?
a) To define the order of execution for interceptors
b) To define the view for an action
c) To define the business logic for an action
d) To define the input validation for an action
Answer: b) To define the view for an action
Explanation: A result type in Struts 2 is used to define how the output of an action should be presented to the user. It determines the view that should be rendered, such as a JSP page, a JSON response, or a PDF document, based on the result type configured in the action.

a) To store values entered by users
b) To store configuration settings for the framework
c) To store action objects
d) To store user session data
Answer: c) To store action objects
Explanation: The “ValueStack” in Struts 2 is a core component that is used to store action objects during the request processing. It provides a way to access and manipulate the action objects, making them available to the views for rendering.
Which of the following is true about OGNL (Object Graph Navigation Language) in Struts 2?
a) It is a configuration file used in Struts 2
b) It is a result type in Struts 2
c) It is a view technology used in Struts 2
d) It is an expression language used to access and manipulate action objects
Answer: d) It is an expression language used to access and manipulate action objects
Explanation: OGNL (Object Graph Navigation Language) in Struts 2 is an expression language that is used to access and manipulate action objects. It provides a convenient way to access properties and methods of action objects in the views for rendering.
What is the purpose of the “ActionContext” in Struts 2?
a) To store configuration settings for the framework
b) To store user session data
c) To store values entered by users
d) To provide access to the current request and response objects
Answer: d) To provide access to the current request and response objects
