[SOLVED] CSE308 Offline Assignment 2

Description

Consider a company producing a Queue Management System. The components of the Queue

Management System are described as follows:

1. Display unit for each of the booths in the service center.
2. A use ATMega32, Arduino Mega or Raspberry Pi for receiving and processing data from

web-based control unit.

1. The display system could be LCD panel or LED matrix
2. An application to control the display units over the Internet.
3. The communication system for communication between the display unit and controller

application

1. We can think of WiFi connectivity through broadband service or mobile data service
2. WiFi service requires WiFi module to communicate with the base station
3. For mobile data we need SIM card for communicating
4. The control unit can control multiple number of display units

You are to implement a web-based system that takes the sales order of the queue management system that

selects the following:

• The name of the Queue Management System specified as follows:

o Deluxe: LCD panel with Raspberry Pi

o Optimal: Arduino Mega with LED matrix

o Poor: ATMega32 with LED matrix

• The communication channel
• The number of display units

You have to determine the cost of the total system as well as description of the system. Cost of the

following must be considered: processor, display, communication module, web-based controller

application, yearly communication cost.You have to use creational design patterns to demonstrate the above-mentioned web-based system. Do

not develop the web-based application here. It is sufficient to demonstrate it through regular input and

output command from the prompts.

Problem 2:

Assume that you are trying to implement syntax highlighting in a programming language editor.

The editor currently supports 3 languages (C, CPP and Python). To perform this, you need to be

able to parse the .c, .cpp and .py source files. Each language has specific rules of parsing. All the

parsers implement an interface named Parser which contains all the functions required to parse a

file. There is an Interface for the fonts of the source codes. The editor uses Courier New, Monaco

and Consolas font for C, CPP and Python respectively. Assume that multiple instances of the

editor cannot run simultaneously. The input will be the file name with extension and the output

will be the selected font while showing environment and parser name when running parsing

method of the editor.

Tasks:

• Identify the design pattern(s) that can best capture the scenario above.
• Implement the scenario in Java
