What are the programming constructs?

  1. Sequential

  2. Selection -- if and switch statements

  3. Iteration -- for loop, while loop and do-while loop

  4. none of the above


Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Sequential - This option is correct. Sequential is a programming construct that represents a sequence of instructions executed in order, one after another.

Option B) Selection - This option is incorrect. Selection is a programming construct that allows the execution of different sets of instructions based on a condition. It includes if and switch statements.

Option C) Iteration - This option is incorrect. Iteration is a programming construct that allows the repeated execution of a set of instructions. It includes for loop, while loop, and do-while loop.

Option D) none of the above - This option is incorrect because the correct answer is option A - Sequential.

The correct answer is option A. This option is correct because sequential execution is a fundamental programming construct that represents the order in which instructions are executed.

Can a for statement loop indefintely?

  1. Yes

  2. No


Correct Option: A

What is a thin-client application?

  1. A browser that uses a plug-in to process user data.

  2. A distributed application where the client program does not process datA. but instead passes data for processing to an enterprise bean running on an application server.

  3. An application that cannot be stopped by a firewall.

  4. An application compiled with the -thin option of the javac command


Correct Option: B

What is a J2EE component?

  1. Special icons for creating the user interface elements for thin clients.

  2. A data module saved to the component area of the database.

  3. A self-contained functional software unit that is assembled into a J2EE application and interfaces with other application components

  4. A JAR file


Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of J2EE components. Let's go through each option to understand why it is correct or incorrect:

Option A) Special icons for creating the user interface elements for thin clients - This option is incorrect. Special icons for creating the user interface elements do not represent a J2EE component.

Option B) A data module saved to the component area of the database - This option is incorrect. A data module saved to the component area of the database is not a J2EE component.

Option C) A self-contained functional software unit that is assembled into a J2EE application and interfaces with other application components - This option is correct. A J2EE component is a self-contained functional software unit that is assembled into a J2EE application and interfaces with other application components.

Option D) A JAR file - This option is incorrect. Although J2EE components are typically packaged as JAR files, not all JAR files represent J2EE components.

The correct answer is Option C. This option is correct because it accurately describes a J2EE component as a self-contained functional software unit that is assembled into a J2EE application and interfaces with other application components.
