- Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…Problem description:1. Below are classes for a project that involves the creation, displaying andevaluation of a polynomial in x. Organize the classes into a project and test theprogram.2. Based on the project, create a project for the same purpose such thatcoefficients of polynomial may be numbers with decimal digits and that theliteral coefficient in each term must be consistent with the other terms (i.e. A term can be added in an existing polynomial only if the literal is the same asthe literal of the existing terms)./*** The following defines a term of an algebraic polynomial that involves only one* literal. 3x^2 is an example of a term where 3 is the coefficient, x is the* literal and 2 is the degree*/public class Term {private int coef; // data member to hold coefficient of a termprivate int degree; // data member to hold the degree of a termprivate char literal; // data member to hold the literal of a term/*** This a constructor that sets coefficient to 0, degree to 0 and…This next program is a little simpler, but it still illustrates some very critical program structures. It also illustrates an idea that is still used commonly, even if the mechanism has evolved with modern tools and alternative languages. We are referring to a menu-based help system. Modern help systems and menus are often represented using an integrated user environment; however, the core concepts behind the help system remain largely unchanged from this assignment. Create an interactive help system for Java programming. The system will incorporate a menu system that interacts with the user, and the appropriate help topic will be displayed, based on an input selection. This program is going to require some research on your part, as well as some programming in Java. Specifically, you will need to find definitions for the Java terms included in your help system. You can read the textbook or scour the Internet for the definitions. They should be no more than a few sentences each; nothing…

You should not use the assembly-part stock control scenario described in lectures. You can make use of other sources for scenario ideas, but you should reference them appropriately. Your answer should include the following: a) A description of the scenario and the relevant objects in it. b) A class diagram illustrating the use of the composite design pattern. c) A description, with code snippets, of an implemented solution to the scenario without using the composite design pattern. d) A description, with code snippets, of an implemented solution to the scenario using the composite design pattern, making reference to how the implementation in c) was adapted. e) Your answers to c) and d) should include a discussion of data structures used, any association, aggregation, or composition relationships, inheritance relationships, and the use of polymorphism
- Your task will be to create a simple text-based simulation that inherits from a pre-existing World class. You must use the World.h provided as a starting point for your code. At least one object in your solution should meaningfully inherit from this class. DO NOT MODIFY THE WORLD CLASS in any way. Note that the World class is abstract and there are a few pure virtual functions for you to implement in your object that inherits from the world. Namely, you will need to implement: void PrintGrid() - This function should print the grid (10 by 10 char array) to standard out. void UpdateGrid() - This function should update your characters' positions on the grid void initGrid() - This function should set your grid up (implement your "starting conditions" here) The scenarios that you will simulate will be confined to a 10x10 grid (defined in the World class as grid) and be subject to at least 10 distinct rules. In addition, there must be at least 2 different objects or “characters”…Computer Science UML is a standard language that allows you to capture different aspects of your system in well-defined graphical models. Some of the models capture static aspects for the system and one will capture dynamic behavior for the system. In this project, you are required to draw an activity diagram showing the actions and events involved in depositing a check to a bank account using a mobile app. In particular, your paper should provide the following: A simple pseudo-code that captures the sequence of that process A detailed activity diagram that maps to your pseudo code you identified Make sure to specify clearly any assumptions you feel important to understand your logic I'm a bit lost on what to do and really just need an example of what this is asking and then suggestions on how to go about doing the assignment.In our engineering school, students can be a CS, SE or CE student. Therefore, four classes are developed: Student, CS, SE, and CE. Because CS and SE are in the same department, you are asked to develop exactly one function foo(…) in class MyProg that can accept an object of CS or SE, but not CE. Which design pattern can be easily applied to accomplish this.
- Develop a program (or find one on the internet) to exemplify and document dynamic binding). A parent and two or more child classes are needed. Shape, Triangle, Rectangle are common examples where Shape is the parent and Triangle and Rectangle are the child classes. Create a project for the program, add the parent and childs classes to it. Use main to exemplify dynamic binding by creating an array or ArrayList of the parent class type and filling it with objects of the child class types. Loop through the array and display all the objects in it by calling their toString method. Then create a method whose parameter is the parent class type. Have main call the method sending it the child types. What the method does is up to you. Heavily document this program since this is not a prescribed assignment. I want to read your words. So I want you telling me what it does, how it does it, and how it has anything to do with dynamic binding. Then using screen capture software, take…The cognitive walkthrough is a formalized way of imagining people’s thoughts and actions when they use an interface for the first time. During a cognitive walkthrough the evaluator needs to ask four questions as below Is the effect of the action the same as the user’s goal at that point? Will users see that the action is available? iii. Once users have found the correct action, will they know it is the one they need? After the action is taken, will users understand the feedback they get? Given below is an action sequence for creating a customized voicemail message on an iPhone. Tap Voicemail. Tap Greeting. Tap Custom. ‘ Tap Record and speak your greeting. When you finish, tap Stop. To listen to your greeting, tap Play. To re-record, repeat steps 4 and 5. Tap Save. Imagine an iPhone interface and create a report of the cognitive walkthrough for the above mentioned task in context with the review questions.Write a function with the interface doRandomWalk(nstep,startPosition), that takes the number of steps nstep for a random walk and the startPosition of the random walk on a straight line, and returns the location of the final step of the random walker. Problem Part B Now, write another function with the interface simulateRandomWalk(nsim,nstep,startPosition) that simulates nsim number of random-walks, each of which contains nstep steps and starts at startPosition. Then, this function calls doRandomWalk() repeatedly for nsim times and finally returns a vector of size nsimcontaining final locations of all of the nsim simulated random-walks. Problem Part C Now write a script that plots the output of simulateRandomWalk() for nsimnstepstartPosition===1000010−10 The resulting plot should look like the following, How do you interpret this result? How can uniformly-distributed random final steps end up having a Gaussian bell-shape distribution.
