- Problem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message. The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well.

- Objectives: Use Javadocs to document a class and methods Design and write a Java class Use fields (instance variables) Write multiple constructors Write accessor methods Write mutator methods Use the this keyword Use string concatenation Round floating point numbers (using Math.round()) Use a Scanner object Description ProduceItem class For this project, you get to design and write a ProduceItem class that stores a description, cost and weight as fields. Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…python: class Student:def __init__(self, first, last, gpa):self.first = first # first nameself.last = last # last nameself.gpa = gpa # grade point average def get_gpa(self):return self.gpa def get_last(self):return self.last class Course:def __init__(self):self.roster = [] # list of Student objects def add_student(self, student):self.roster.append(student) def course_size(self):return len(self.roster) # Type your code here if __name__ == "__main__":course = Course()course.add_student(Student('Henry', 'Nguyen', 3.5))course.add_student(Student('Brenda', 'Stern', 2.0))course.add_student(Student('Lynda', 'Robison', 3.2))course.add_student(Student('Sonya', 'King', 3.9)) student = course.find_student_highest_gpa()print('Top student:', student.first, student.last, '( GPA:', student.gpa,')')Object-Oriented Programming OvalDraw Plus (Java code) Summary: Create a graphical application with Java that that draws an oval Prerequisites: Java, VS Code, and Terminal Create a graphical Java application that runs on Microsoft Windows and MacOS that draws an oval centered in the main application window when the programming starts. The oval should automatically resize and reposition itself when the window is resized. In this activity you will start with our OvalDraw application in our sample code, review the code, and then make incremental improvements to the application. Be sure to make the resulting application uniquely your own by adding standard comments at the top application (i.e. your name, class, etc.), changing the names of variables, and adding small features. Finally, be sure to save your work as you will often be asked to submit it as part of an assignment. Be sure to review the example OvalDraw project in the Java section of our example code repository.

- Java OOP UML design Design a lighting control system for a smart home. It should allow lights from different manufacturers and with different specifications to be controlled by the same app. The app controls groups of lights. The groups are user-defined: the user can add a light to a group and remove a light from a group. Some lights can dim smoothly, while some are just on/off. Some lights may change colour. Some lights can dim and change colour. . Design an object-oriented application for the light system. Draw a simple UML diagram showing the design of each class. You do not need to list getters/setters or constructors. The application should have the following features. The lights will have a method to change intensity and colour. There will be a method to change the intensity and colour of all the lights in a group. All the lights in the group will be changed to the same intensity and colour. Write pseudo-code or point-by-point English to clearly describe how these two methods…please type the code java programming please use the first question Boolean variable for true or false This problem set will test your knowledge of System I/O, and variable assignment. Your task is to create several different java classes (.java files) that will produce a specific output based on the user input. All input will be given to you either as a command-line argument or typed in from the keyboard. Below you will find directions for each class you need to create. Please make sure that the class name and java file name match the name specified in the directions below. For example, the code for the problem named "IsSame" should be put in a java file name IsSame.java and that file should have a class named public class IsSame. IsSame This program will accept two user inputted values from the console. The values will be words. The program should print "true" if the words are equal and "false" if the words are not equal. The last string that this program should print is "true"…True or False ___(25) Java’s constructor name is exactly the same as the class name. ___(26) Java allows multiple constructors to be defined within a class. ___(27) is-a relationship is similar to has-a relationship in Java.
