Model a real-life object as a Java class with at least one attribute and an instance method. Write a main method to create an instance of the class, assign a value to the attribute, call your method, and demonstrate that the value of the attribute changed and that the method successfully completed what it was supposed to do. I need one that programs a DVR with hours, minutes, and dates.

Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.

Create a UML class diagram of the application illustrating class hierarchy, collaboration, and the content of each class. There is only one class. There is a main method that calls four methods. I am not sure if I made the UML Class diagram correct. import java.util.Random; // import Random packageimport java.util.Scanner; // import Scanner Package public class SortArray{ // class name public static void main(String[] args) { //main method Scanner scanner = new Scanner(System.in); // creates object of the Scanner classint[] array = initializeArray(scanner); System.out.print("Array of randomly generated values: ");displayArray(array); // Prints unsorted array sortDescending(array); // sort the array in descending orderSystem.out.print("Values in desending order: ");displayArray(array); // prints the sorted array, should be in descending ordersortAscending(array); // sort the array in ascending orderSystem.out.print("Values in asending order: ");displayArray(array); // prints the...

Please written by computer source 1. Model a real-life object as a Java class with at least one attribute and an instance method. Write a main method to create an instance of the class, assign a value to the attribute, call your method, and demonstrate that the value of the attribute changed and that the method successfully completed what it was supposed to do. The main method can be created in a separate driver class (e.g. MyDriver.java) within which you will create an instance of the object class. For example, if the name of the object class is Car (meaning, you are coding Car.java) then you can create an instance of Car inside MyDriver.java.

In Java!!!!!This is a multi-part question. Consider the following UML diagram on attached image: 1.Write Java classes corresponding to the UML diagram. 2. Write getters and setters for all classes 3. Write non-default constructors for each class that initializes all instance variables to values passed as arguments to the constructor 4. Write toString method for each class 5. Modify Vehicle class to maintain inventory (list of all vehicles created) and print the list. What variable(s) you need to add? What additional method(s) you need? What else needs to be modified in the Vehicle class? Do you need to modify any of the descendant classes and explain your answer (if not: why not; if yes, describe what changes). Vehicle {Abstract} manufacturer:String - color:String Car Truck TwoWheeler {Abstract} -numberOfDoors:int -numberOfAxels:int -passengerSeats:int -fuelType:String -fuelLevel:int -fuelType:String -numberOfSeats:int -fuelLevel:int Truck Motorcycle -numberOfAxels:int -fuelType:String...

We already have the address and vehicle class for the system below. We will need a CarShow class with IsSanctioned() method, Owner class with IsOwner method and a main class that creates objects and implements all our existing classes. Use the class diagrams. Make sure to include respective attributes, setters, getters and constructors in your code Explain your code in a few words.
