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:
class Vehicle
{
String s = "This is my vehicle" ;
}
class Car extends Vehicle
{
String s = "This is my car" ;
{
System.out.println( super .s);
}
}
class Truck extends Car
{
String s = "This is my truck" ;
{
System.out.println( super .s);
}
}
public class MainClass
{
public static void main(String[] args)
{
Truck t = new Truck ();
System.out.println(t.s);
}
}

- Polymorphism in Java In the class “Phone”, there is a method call() which in default prints “Calling Emergency services…”. Override this method by accepting a string called number. Accept for a number as input. If input is 0, call the default method. Inputs 1.

- language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…The class diagram below shows an Order class that "has a" Customer and zero or more Items.

- Assume the Book class is defined as follows: public class Book{ enum Type type {FICTION,NON_FICTION}; public int isbn; public Type type; Book(int isbn, Type type){ this.isbn = isbn; this.type = type; }} Define filterBooksOfGivenType method that shall return ArrayList of Book of the type specified in parameter.Create a class Animal Create a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…Using JAVA Part A) Design a class Message that models an e-mail message.

- Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A,B,C,D,E" is correct.
