A counter variable is normally used in a program to keep track of the current count value.Create your own counter data type which is able to perform common counter operations such as increment (by one) the counter value and decrement (by one) the counter value. It is also able to set the counter to a specific value and to retrieve the counter value. The minimum value the counter can attain is zero, while the maximum value attained is stored in attribute maxValue. The class should have the following private members (attributes): (first picture) In the main program, test the workablity of your member functions by first setting an initial value to the counter. Display this value before proceeding. Then test other functions by randomly incrementing and decrementing the object’s value. Be sure to keep track of your actions. At the same time you should also make sure that your minimum value should not be less than zero. Once this is reached you will not be allowed to do further decrements.…

7-2 Discussion: Interpreting Multiple Regression Models Previous Next In this discussion, you will apply the statistical concepts and techniques covered in this week's reading about multiple regression. You will not be completing work in Jupyter Notebook this week. Instead, you will be interpreting output from your Python scripts for the Module Six discussion. If you did not complete the Module Six discussion, please complete that before working on this assignment. Last week's discussion involved development of a multiple regression model that used miles per gallon as a response variable. Weight and horsepower were predictor variables. You performed an overall F-test to evaluate the significance of your model. This week, you will evaluate the significance of individual predictors. You will use output of Python script from Module Six to perform individual t-tests for each predictor variable. Specifically, you will look at Step 5 of the Python script to answer…

Guide to working through the project Steps: Write the GradeBook constructor that reads student information from the data file into the ArrayList roster). For now, ignore the grades. Test your GradeBook class before proceeding to the next step. Create the Grade class. Test your Grade class before proceeding to the next step. Modify the Student class to include an ArrayList of Grade. Test the Student class before proceeding to the next step. Finish writing the GradeBook constructor to process the grades as they are read in from the data file. Test the GradeBook class before proceeding to the next step. Add additional functionality to the GradeBook and Student classes one method at a time. Here is Grade.jave code is shown below. public class Grade { // TODO: complete this class as described in this task write-up } GradeBook Class The GradeBook class has a single instance variable roster, an ArrayList of Student. This class performs all operations related to the scores of all…
Blue-Eyed Island: A bunch of people are living on an island, when a visitor comes with a strangeorder: all blue-eyed people must leave the island as soon as possible. There will be a flight out at8:00pm every evening. Each person can see everyone else's eye color, but they do not know theirown (nor is anyone allowed to tell them). Additionally, they do not know how many people haveblue eyes, although they do know that at least one person does. How many days will it take theblue-eyed people to leave?

Develop a Shipping Calculator Java application, which contains the concepts of a Java object and class. This Java Program must include the declaration and definition of object and class. The steps for the program are outlined below: Create a Java class named Package that contains the following: Package should have three privateinstance variables of type double named length, width, and height. Package should have one privateinstance variable of the type Scanner named input, initialized to in. No-args(explicit default) public constructor, which initializes all three double instance variables to 1.0. Initial(parameterized) public constructor, which defines three parameters of type double, named length, width, and height, which are used to initialize the instance variables of same name. Public copyconstructor, with a parameter of type Package, used to duplicate an existing Package object. Three public void methods named inputLength,inputWidth, and inputHeight. Each method will…
Project Description: The goal of this project is to write a program that can read data from any publicly available IoT source device and display it clearly to the user. The program will need to be written in Python (or any other programming language of your choice) and will need to include the following features: 1. Data Reading: The program should be able to read data from any publicly available IoT source device, such as a camera or any other sensor. The type of device is up to you, but they should be able to provide a valid URL for the device. The program should read the data from the device at regular intervals and store it in a data structure. 2. Data Display: The program should display the data that it reads from the IoT source device in a clear and easy-to-read format. The display could be in the form of a text-based output or a graphical interface, depending on your preference. The display should include information about the source sensor, as well as the data that was read…
