Write a java program to create any number of classes with one controlling class to implement Inheritance, Encapsulation, Polymorphism, Arrays, String, and Math classes Concept. ) Each class can have multiple methods and constructors as per your wish. (ii) Any number of variables are allowed to use it inside the program. (iii) Any Number of objects are allowed to create in the controlling class. (iv) You have to use Encapsulation, Polymorphism, Arrays, String, and Math classes. The following information is required for the assignment Properties with proper data types Methods with proper return types and scope Demonstration of OOP feature- (Inheritance) Demonstration of user-defined package Proper naming convention Proper comments in each program and within program The purpose of each code should be explained.

class A{}; class B{}; int main() { A obl,ob2; B ob3; ob3=ob2; } (a)Why does Overloading occur? Is there any error in this code section? If there is any, explain with reason.
{In Java Programming Please} Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class…

Object Oriented Programming (Java): True or False Statements with one line reasoning: 1. The implementation of inheritance always involves writing a few less lines. 2. The following class declaration is incorrect: public final class Class extends OtherClass {...} 3. Inheritance is only useful if specialization is used. In fact, specializing we inherit in the subclass (or subclasses) members of the superclass that we must not rewrite. Instead with the generalization we create an extra class, and then we write more code. 4. The super keyword allows you to call superclass methods and constructors. The keyword this allows you to call methods and constructors of the same class. 5. Multiple inheritance does not exist in Java because it does not exist in reality.
Create a Java program demostrating the following aspects of OOP: You must create an UML. class diagram for all the classes and interfaces in the program. Use Java interface and method overriding appropriately. Inheritance/Interface and polymorphism. Your program the base class of interface should be used as the variable/parameter type to demostrate polymorphism. Overloading using either methods or constructors. Appropriate use of this keyword. Correct use of access modifiers (public, private) in an appropriate way. Correct use of static variable and instance variable. Passing object as parameter to a method. Caling method from another method of the same class. Creating user defined classes with Encapsulation principle consideration. You are free to pick any topic/system to accomodate the above points but please keep it simple. The application does not have to be real world application meaning you can use an imaginary system for the mentioned points. Neverthless, you should be aware…
Writing a java program that contains a class representing the vehicle And it contains basic specifications such as safe speed It is pre-installed and another variable for velocity is an amount The speed of the car and can be increased or decreased, and others Other specifications as desired by the student, as well L-car functions such as movement, stop and reverse, among others Of the jobs, according to the request of the student, so that the car is built By moving at a certain speed and when increasing and equaling the speed For safe speed, it will alert you when the speed is exceeded Safety the car stops permanently and speeds up Become zero. Note: Not all concepts are used In object-oriented programming
Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note. The note’s value is an integer. it is specified by counting how far the note lies above or below the A note that orchestras use in tuning ( https://en.wikipedia.org/wiki/A440_(pitch_standard) if needed to check ) . In counting "how far", you should count every key, both the white and black notes on a piano. So the A note above Middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz) quarter note. Include methods to set a note to a specified length and value. Write methods to retrieve information about a note,…
Write a program in Java to perform the followings, (i) Design one parent and two child classes. Names of parent and child classes along with the names of their variables and methods should be taken from real-life by yourself. Parent class should have at least two variables, one parameterized constructor and one method to perform any meaningful operation/calculation with the variables. Child classes should have at least one additional variable declared within (ii) (iii) them and one parameterized constructor, and a toString method. (iv) Design another class and a main method inside it. Declare at least one object of each of the two child classes using parameterized constructor. Call the method of the parent class with these objects to perform the particular operation/calculation on these objects and show the result. Display values of all the variables of these objects using toString. Write the Java program using Eclipse IDE, copy and paste the code along with the output in a word file.…
Write a c++ program to implement the hierarchical inheritance 1. Write getter/setters, display function, parameterized, default and copy constructor. 2. Write a calculateSalary() function in the Typist class and override the definition in permanent and casual. 3. Write a ‘main’ function and create objects of all classes in main and call the public methods of all classes.

Images/pictures of your code is not accepted. Write a program using inheritance to do the following tasks: a) Create an abstract class Employee with the variables id, name and salary. b) Declare an abstract method calculateTax(double) which calculates the Tax on Salary of an employee. c) Inherit the class Employee into a subclass Employee Tax. In EmployeeTax class do the following tasks: i) Create a method getEmployeeDetails) to read id, name and salary of an employee. i) Inside the calculateTax() method calculate the tax using the following conditions. Salary Tax >=2000 20% >=1500 15% >=1000 10% <1000 5% iii) Create a method netsalary0 in the subclass to print the salary. Note: salary=salary-tax
