Program Plan Intro
Object-oriented analysis and its advantages.
Expert Solution & Answer
Program Description Answer
Approach of analyzing system using objects is known as object-oriented analysis.
Explanation of Solution
Object-oriented analysis is based on objects and their interaction with the system. Objects can be any identifying entity such as a person, machine, place or any transaction which interacts as a group.
When one buys a product from market then customer, product, shopkeeper, the company all interact with each other and thus they are distinctive objects. Object−oriented analysis is an approach to analyze the system through its group of objects and their functions to create an object model. Object model is a system based on object and its interactions in the form of functions.
Advantages of object-oriented analysis:
- Focus is on object or data and not on procedures or functions.
- Effective in utilizing concepts of data encapsulation and data hiding.
- It develops modules which can be easily reused and can be upgraded from smaller modules to large modules.

How do we find the possible final values of variable x in the following program.
Int x=0; sem s1=1, s2 =0;
CO P(s2); P(s1); x=x*2; V(s1);
// P(s1); x=x*x; V(s1);
// P(s1); x=x+3; V(s2); V(s1);

- Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forwardIf a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a) Give an example of when an application might want to receive such ICMP messages. (b) Find out what an application has to do, on the operating system of your choice, to receive such messages.

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forwardusing r languagearrow_forward8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods: A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list. A method named clear that should clear the CashRegister object’s internal list. Demonstrate the CashRegister class in a program that allows the user to select several items for purchase.
