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:
Identify all the members (variables and methods) of a class Company.
Step by step
Solved in 2 steps
- Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.Complete the method in Java. Name of the public class is Assignment1.javaType a Java method constructor for the "book" Class, which takes values as parameters for all of these attributes.The" book " Class has the following properties: title (string), author (string), year (int), pages (int).
- class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g. Circle (int xCoordinate, int yCoordinate, double radius) { this.xCoordinate= xCoordinate; this.yCoordinate= yCoordinate;…Given the following class. (JAVA) public class FamilyMember { public String drink( ) {return “cup”;} public String eat( ) {return “fork”;} } Write a Baby class that is derived from the FamilyMember class. The Baby class has an instance variable for the age, a default constructor, and a constructor that accepts an integer. Include any other necessary methods. If a baby is older than 3 years, print that “it eats with its fork”; otherwise, “it eats with its hands”.The following code is in Java: public class Vehicle // Superclass { private double cost; public Vehicle(double c) { cost = c; } (Other methods . . .) // assume these are given and they’re OK. } public class Car extends Vehicle // Subclass { private int passengers; public Car(int p) { passengers = c; } (Other methods . . .) // assume these are given and they’re OK. } 1) What problems are in the code above?2) What is needed to fix the issue of the code?
- Complete the Car class below so that it inherits from the given Vehicle class. Cars lose value over time. In this example, you should assume that the value is reduced by 25 cents per mile driven, until it reaches zero. Do not add any instance variables to the Car class. /** Represents a car.*/public class Car // TODO: Inherit from Vehicle{ // Do NOT add any instance variables public Car(double purchasePrice) { // TODO: Complete } // TODO: Override the getValue method}1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result 2/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 3/Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in…(Java) Question 5 Explain the answer step-by-step and include verbal explanation. Thank you! Write an interface as follows: The interface is named ServiceReminder It has one method named timeForService that has no parameters and returns a boolean variable. Now, update the below class so that is inherits from ServiceReminder Note that the next service date should be 90 days from the last service public abstract class Car { private double gasGauge; private double currMileage; private String color; private String make; private String model; private int daysLastService; public Car(String color, String make, String model, int daysLastService) { this.color = color; this.make = make; this.model = model; gasGauge = 0.0; currMileage = 0.0; this.daysLastService = daysLastService; } @Override public String toString() { return "Make: " + make + "\nModel: " + model + "\nColor: " + color…
- This composition example contains classes Date, Employee and EmployeeTest .Class Date declares instance variables month, day and year to represent a date. The constructor receives three int parameters. It has method checkMonth to validate the month—if the value is out-of-range the method throws an error message. same goes for year and day. Provide getters, setters and toString method. Class Employee has instance variables firstName, lastName, birthDate and hireDate.Members firstName and lastName are references to String objects. Members birthDate and hireDate are references to Date objects. This demonstrates that a class can have as instance variables references to objects of other classes. The Employee constructor takes four parameters—first, last, dateOfBirth and dateOfHire. The objects referenced by the parameters are assigned to the Employee object’s instance variables. When class Employee’s toString method is called, it returns a String containing the employee’s name and the…The following code is in Java: public class Vehicle // Superclass { private double cost; (Other methods . . .) // assume these are given and they’re OK. } // Subclass public class Car extends Vehicle { public Car(double c) { cost = c; } }1) What is the problem with the code?2)How can it be fixed?The BankAccount class models changes to the balance of a person’s savings account. public class BankAccount { public BankAccount(String name, double initBal) public double getBalance() public String getName() public void deposit(double amount) public void withdraw(double amount) public void transferTo(BankAccount otherAcct, double amt) public boolean equals(Object other) private String acctName; private double balance; } Provide the code for the transferTo(…) Briefly explain why there is no setBalance() method in this class.
