  1. Make the information available from a singleton

  2. Store the information in the ServletContext

  3. Store the information in an HttpSession

  4. Store the information in a Properties file


Correct Option: C

AI Explanation

To answer this question, you need to understand how dynamic information can be made available to all servlet requests sent to an application. Let's go through each option to understand why it is correct or incorrect:

A) Make the information available from a singleton - This option is incorrect because a singleton is a design pattern that ensures a class has only one instance and provides a global point of access to it. While a singleton can be used to store and access dynamic information, it does not guarantee that the information will be available to all servlet requests.

B) Store the information in the ServletContext - This option is incorrect. The ServletContext is an interface that provides a way for servlets to communicate with the servlet container. While the ServletContext can be used to store and share information across servlets, it does not automatically make the information available to all servlet requests.

C) Store the information in an HttpSession - This option is correct. The HttpSession is an interface that provides a way to store user-specific information across multiple servlet requests and sessions. By storing dynamic information in the HttpSession, it can be accessed by all servlet requests sent by the same user.

D) Store the information in a Properties file - This option is incorrect. A Properties file is a file format commonly used to store static configuration data. While a Properties file can be used to store information, it does not provide a way to make that information available to all servlet requests.

The correct answer is C) Store the information in an HttpSession. This option is correct because the HttpSession allows for the storage of dynamic information that can be accessed by all servlet requests sent by the same user.

      2. white, black and gray

      3. white,red,blue

      4. black, blue, and gray


      Correct Option: B

      AI Explanation

      To answer this question, we need to understand the concept of color mixing. When we mix different colors, we can create new colors. The primary colors, which are red, blue, and yellow, are the building blocks for all other colors. By mixing primary colors, we can create secondary colors, such as purple, green, and orange.

      Option A) Purple, green, and red - This option is incorrect because it includes red, which is a primary color and cannot be obtained by mixing other colors.

      Option B) White, black, and gray - This option is correct because it consists of equal amounts of all basic colors. White is the absence of color, black is the combination of all colors, and gray is a neutral color.

      Option C) White, red, and blue - This option is incorrect because it does not include equal amounts of all basic colors. It includes white, which is the absence of color, and red and blue, which are primary colors.

      Option D) Black, blue, and gray - This option is incorrect because it does not include equal amounts of all basic colors. It includes black, which is the combination of all colors, and blue and gray, which are not equal amounts of the basic colors.

      The correct answer is B. This option consists of equal amounts of all basic colors - white, black, and gray.
