The term "polymorphism" means: O A method can have multiple return types. A class can have multiple names. The exact method that is called is determined by the object's type, not the variable's type. The exact method that is called is determined by the variable's type, not the object's type.

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:
Step by step
Solved in 2 steps
- 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…Method,Field can be accessed from the same class to which they belong.Class object method This program has three methods and two constructorsone constructor has one parameter and the other none The class has two primitive variables one static and the other notThe static member is initialized to greater than 0 the non-static to 0 Variables in two methods are assigned with the static member main() has an initialized variable with a value not the same as others in the program; it is used as the argument to one of the constructors; this value is used to assign a value to the static class variable The constructor that takes no argument has a variable declared with the same name as the static variable, it is initialize by the non-static variable A.Demonstrate and explain the displayed results of objects created in the following order Constructor(arg)Constructor() B.Create a second program to Demonstrate and explain Constructor()Constructor(arg) Iolecnotes Assignment 4.

- T/F A method defined in a class can access the class' instance data without needing to pass them as parameters or declare them as local variables.Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…True or false: A class object can be passed to a function, but cannot be returned by a function.
- True or False If a method belongs to a class, then you must write a method’s definition inside the class.Activity 1 - C++ Language Write a C++ class with the following properties and methods Create a class named BANK ACCOUNT with public properties ACCOUNT NUMBER and BALANCE; - Create a method DEPOSIT that accepts an argument AMOUNT Which stores/add the given AMOUNT in the BALANCE property. - Create a method WITHDRAW that accepts an argument AMOUNT Check the AMOUNT value if less than or equal to the object's BALANCE. Deduct AMOUNT from the current BALANCE if true and return true; Return false if the condition wasn't met. Create a method DISPLAY to show the ACCOUNT NUMBER and current BALANCE of the objectPlease 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.
- Month Class Exceptions Write a class named Month. The class should have an int field named monthNumber that holds the number of the month. For example, Janauary would be 1, February would be 2, and so forth. In addition, provide the following methods: A no-arg constructor that sets the monthNumber field to 1. A constructor that accepts the number of the month as an argument. It should set the monthNumber value to the value passed as the argument. If a value less than 1 or greater than 12 is passed, the constructor should throw an InvalidMonthNumberException. A constructor that accepts the name of the month, such as “January” or “February”, as an argument. It should set the monthNumber field to the correct corresponding value. If an invalid name is passed, the constructor should throw an InvalidMonthNameException. A setMonthNumber method that accepts an int argument, which is assigned to the monthNumber field. If a value less than 1 or greater than 12 is passed, throw an…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. Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…True or False The get accessor can be thought of as a method that returns the class property’s value.
