JAVA CODING QUESTION. Object-oriented and constructor chaining!!! Build a "country" class. A country object will have 2 attributes its name and an array of the names of football stadiums in the country You have to assume there is a football stadium class that consists of just one constructor that has only one input parameter, which is its name. Add the following constructors to the country class: 1) Country(String country_name)  //country has no football stadium 2)Country(String country_name, String football_stadium_name) //country has exactly 1 football stadium 3)Country(String country_name, football_stadium[] football_stadiums) //country has multiple football stadiums YOU HAVE TO USE CONSTRUCTOR CHAINING!!   After coding answer the following question in words: When making a country object what is the maximum amount of constructor methods that are called and what is the minimum amount that will be called. Write an example for both situations

A field has access that is somewhere between public and private. static final Opackage Oprotected

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…

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks:                                                                        Bonds: Purchase date (Date)                                                   Purchase date (Date) Purchase price (double)…

Car Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…

JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types:…
