Cash Register program in Java 1. The driver class should initially fill the register with 0x$100, 0x$50, 10x$20, 20x$10, 20x$5, 0x$2, 50x$1, 80x$0.25, 50x$0.10, 20x$0.05, 100x$0.01 2. The program should ask the user the following: Make a sale make change print balances exit 3. For a sale: the program class should prompt for the cost and how much of each type of currency were given 4. If the register can not make the correct change, print an appropriate message 5. For making change: the program should ask which currency is being provided and how much of that currency, then it should output what currency is being given - example, make change, provide 4 quarters, register gives 1x$1 - example, make change, provide 50 dimes, register gives 1x$5 OR 5x$1 OR 4x$1, 4x$0.25 6. For print balances, just show what is currently in the register of every currency 7. Calculate Big-Oh for all 3 processes 8. Calculate actual operations for making a sale and print out (don't forget to include the cos...

Object Oriented Concepts: (Inheritance, Polymorphism, Abstract classes, Interfaces, Exceptions and some other concepts)Answer the following questions as briefly (but completely) as possible: 1- What is the printout of running the class C (via the command “java C”) in the code below (saved in C.java)? (And, is that what you expected?) class A { public     A()     {         System.out.println("A's no-arg constructor is invoked");     } } class B extends A { } public class C { public     static void main(String[] args)     {         B b = new B();     } } 2- What problem do you expect to see if compiling the program below? What was the error(s), if any, actually produced? class A { public     A(int x)     {     } } class B extends A { public     B()     {     } } public class C { public     static void main(String[] args) ...

A class is a programmer-defined data type that describes what an object of the class will look like when it is created. It consists of a set of variables and a set of functions. A class is repository of functions that any main program may use. In this project you will create two classes and two main drivers to test the classes. Part I Part I will produce 2 files. Geometry.h file is the Geometry class with its members and functions. main cpp file tests all the code in the Geometry class. The textbook examples place the class code in the same file as the main function, but your code will be more re-usable if the class is defined in a separate file – Geometry.h . The header file will need to be included in the program as you did in the Airline Problem and the array.h file. The final version of the Geometry class (Geometry.h) will include: Three constructors:  Constructor 1 – receives 2 integer values for length and width. (rectangle) Calls checkNum to validate each value. Assigns val...

Introduction In the popular game Mastermind, one player creates a secret code of four pegs, each of which can be chosen from one of six colors. (The number of pegs and colors may be different than this in different versions, but your implementation will use these values, but be extendible to other values. Also, a color can be reused, thus there really are six choices for each of the four pegs.) The other player then has to guess the color of each peg, with the order mattering.The player who made the secret code then has to give feed back to the player guessing. This feedback is in the form of white and black pegs. A black peg means that the guesser has chosen the correct color in the correct slot. These are first “calculated” and awarded. Once these are counted, these pegs are ignored. Then the white pegs are awarded. These are for pegs that are the correct color but are in the incorrect slot. There is no “double dipping” of pegs in the response, so the sum total of white and black peg...

(Body Mass Index Calculator App) The formulas for calculating the BMI are BMI = (weightInPounds × 703)/(heightInInches × heightInInches) or BMI = (weight In Kilograms)/(height In Meters × height In Meters) Create a BMI calculator app that allows users to enter their weight and height and whether they are entering these values in English or metric units, then calculates and displays the user’s body mass index. The app should also display the following information from the Department of Health and Human Services/National Institutes of Health so that users can evaluate their BMIs: BMI VALUES Underweight: less than 18.5 Normal: between 18.5 and 24.9 Overweight: between 25 and 29.9 Obese: 30 or greater Buy now CONTACT DETAILS For any other questions or other tasks please feel free to contact me via email: mhassnainjamil@gmail.com via WhatsApp: +92-324-7042178 via skype: hassnainjamil1

Database Systems Some friends of yours are hoping to set up a data driven website to support their home business selling second-hand children clothes, and have asked for your advice on the database design side. They need a database to list all the available items for customers to purchase, and also want to have a user comments system so that visitors can give feedback on purchased items as well as buy them. They are not database experts, and they have asked you to devise a database model they could use. Their ISP has said they can mount and operate a database on their account if given a set of relational tables, which describe it, so this is ultimately what they want you to produce. As a minimum, they would like to store the following information about each item of clothing: the kind of garment, colour, size, material, gender (where appropriate), condition, age, and how much it costs, plus feedback once sold, if available. For customers they would want to record name, postal address, e...

The 8-puzzle problem In this project you will implement a solution to the 8-puzzle by state-space search, using the search engine described in the lectures, and experiment with search strategies. What you must do Implementing 8-puzzle search In the search2 folder in the Java download on the COM1005/2007 MOLE site is the code for the simple search engine and for Jugs problems. Note that you may have to recompile the code for your version of Java. • Following the instructions in section 2.9 of the lecture notes, write classes to implement a state-space search for 8-puzzle problems. • You should not need to change the code for the search engine except perhaps to control how much it prints as a search proceeds, and to stop the search after a given number of iterations (in an 8-puzzle the search tree can become large). • Test your implementation with breadth-first searches for the following initial con- figurations and the same goal state as above: Experimenting with Search Strategies The s...

Introduction Firstly, this worksheet is one of the worksheets from which your laboratory worksheets portfolio of work will be assessed. This worksheet is about empirically evaluating how scalable a number of single population heuristic search methods are at solving the Travelling Salesman Problem (TSP) when applied to a number of different sized problems. The aim is to evaluate and demonstrate how well each of the methods performs as the size of the problem increases. The overall objective of this worksheet is to produce; present and report on, a Java program that is capable of solutions the TSP on a number of different sized problems using a number of different heuristic search algorithms (see below). Solving the TSP Problem The Travelling Salesman problem (TSP) has been described fully in the lectures. The purpose of this worksheet is to: 1) Implement a number of the algorithms (listed below) to solve the TSP 2) Compare the algorithms on a number of different sized datasets 3) Report...

Introduction: For this lab, you will do some work on a GUI program. Most of the work is related to actions, buttons, menus, and toolbars.When you turn in your work for this lab, you should also turn in an executable jar file of your program, in addition to all the files from your Eclipse project. See the last section on this page for information about how to create executable jar files. To begin the lab, create a new project in Eclipse and copy-and-paste both directories – guidemo and resources -- from the code directory into your Eclipse project. The guidemo directory is a package that contains the Java code of the program. The resources directory has several sub-directories that contain image and sound resources used by the program. You will be working only on the code in the guidemo package. The code directory also contains an executable jar file of the completed program, GuiDemoComplete.jar. You can run this jar file to see how the program should look when it's done. In the inc...
