Chapter 12, Problem 1D
Explanation of Solution
Object oriented design:
- A set of process that is involved in developing a set of classes for problem solving is called as object oriented design.
- It is considered as most powerful complement to the top-down design for developing a reliable, cost-effective software system.
- The goal of top-down design is developing set of black-boxes and its associated interfaces.
- A top-down design seeks for the function whereas the Object Oriented Design seeks for an Object.
Process of Object oriented design OOD:
There are many different ways to process OOD and they are as
- Look for object candidates.
- While considering a problem definition, the main goal is to define a set of objects that aids in solving the problem.
- The objects that are chosen are often described through nouns.
- The nouns present in the each problem statement are considered and underlined one by one based on the below mentioned factors.
- Identify instance variables.
- Based on the value possessed by the instance variable the instance variables are identified.
- Most of the instance variables are considered to have primitive value whereas some of them seem to have complex types...

Using XML, design a simple user interface for a fictional app. Your UI should include at least three different UI components (e.g., TextView, Button, EditText). Explain the purpose of each component in your design-you need to add screenshots of your work with your name as part of the code to appear on the interface-.
Screenshot is needed.

- R languagearrow_forwardUsing R languagearrow_forwardCompare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forward
