OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

Which statement about default constructors is correct?

Question 9 options:

	It is a parameterless constructor.
	It does not accept argument(s).
	It initializes the object's fields with the value 0 or null.
	All of the above.

Expert Solution

Step 1

A default constructor is a constructor that takes no arguments, i.e., it is a parameterless constructor. It is automatically generated by the compiler if no constructor is explicitly defined in the class.

java Assignment Description: Write a class named Car that has the following fields: The yearModel field is an int that holds the car’s year model. The make field references a String object that holds the make of the car. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods. The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Constructor: The constructor should accept no arguments. Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel. No need to assign anything to the make and assign 0 to speed.

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)…

Brieﬂy describe the purpose of a constructor.
Please provide UML diagram Problem Statement Design a class named Car that has the following fields: year: The year field is an integer that holds the car’s year. make: the make field is a String that holds the make of the car. speed: the speed field is an integer that holds the car’s current speed. In addition, the class should have the following constructor and other methods: Constructor: The constructor should accept the car’s year >model and make as parameters. These values should be assigned to the object’s yearand make fields. The constructor should also assign 0 to the speed field. Accessors: design appropriate accessor methods to get the values stored in an object’s year, make, and speed fields. accelerate: the accelerate method should add 5 to the speed field each time it is called. brake: the brake method should subtract 5 from the speed field each time it is called.
True or False Class fields are almost always declared public in order to make their values easily accessible to code outside of the class.
True or False The get accessor can be thought of as a method that returns the class property’s value.
True or FalseIn structs, all fields and methods are public i.e. all the data can be accessed and changed and all the methods can be called by those who use it.
INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…
In PYTHON Design a class named Car that has the following fields: yearModel: The yearModel field is an integer that holds the car's year model (e.g, 1959). speed: The speed field is an integer that holds the car's current speed.

These values should be assigned to the object's yearModel and speed fields.The constructor should also assign 0 to the speed field. Accessors: Design appropriate accessor methods to get the values stored in an object's yearModel and speed fields. accelerate: The accelerate method should add 5 to the speed field each time is called. brake: The brake method should subtract 5 from the speed field each time it is called. Next, design a program that creates a Car object, and then calls the accelerate method five times. After each call to the accelerate method, get the current speed ofthe car and…
