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:
Let’s build a Player Portfolio System that has an abstract class.
-
- Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example:
abstract class PlayerA {
private String name;
public String getNameA()
{
return name;
}
public PlayerA(String name) {
this.name = name;
}
abstract public int getStatsA();
abstract public String getSportA();
}
- Create NFL Player and NBA Player concrete classes that will extend Player abstract class.
- Create a main method to implement your classes

- Let’s build a Player Portfolio System that has abstract classes. Inheritance using Abstract: Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example: Abstract class PlayerA {private String name;public String getNameA(){return name;}public PlayerA(String name) {this.name = name;}abstract public int getStatsA();abstract public String getSportA();} Create NFL Player and NBA Player concrete classes that will extend Player abstract class. Think of meh=thods for these two classes and implement them Develop appropriate unit tests.Vehicle is an abstract class. Create the Airplane class as a subclass of Vehicle. Extend and override Airplane as necessary to meet the criteria below. The travel method should return the distance traveled by the Airplane object. CODE: abstract class Vehicle { public abstract double travel(double time);} //add class definitions below this line //add class definitions above this line public class Exercise2 { public static void main(String[] args) { //add code below this line //add code above this line }}public abstract class Staff implements Payroll { private String name; private String department; private double baseSalary; private LocalDate joinedDate; What to do/change 1. (5) Provide the following: (2.5) Provide a fully parameterized constructor. (2.5) Provide getters and setters for all attributes. Base Salary must be a non-negative value (make all the necessary changes) 2. (5) Add a toString method. The string it returns should first include the name of the class (Doctor and Nurse should be subclasses of Staff). It should look similar to to the following: Expected Output: Doctor Name: Dr. Ahmed Department: Family Medicine Base Salary: 10000.0 Joined Date:2019-03-04
- Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.Shape -width: double -length: double +allmutatorMethods Shapes2D Shapes3D -height:double *calSize():double +calVolume():double 1. Define class Shape, 2DShape and 3DShape as per UML class diagram given. 2. Define all mutator methods(set and get) for all classes. 3. Define methods calArea() with formula area - width * length for 2DShapes. 4. Define methods calArea() with formula calvolume, volume = width*length*height for 3DShapes. In the main program, declare and set data in 1 object of 3DShapes. Create an array OR ArrayList of 2DShapes, set and display the info of all objects as shown in the output. 5.public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.

GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18-ARID-2891 and CircleM.JibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*lengthIndications:Person is an abstract class containing the abstract method Print().In Teacher and Student the method print() will print the information of either Teacher or Student.Write the class university corresponding to the following UML diagram. It contains three attributes.Tab is an array of Person. sizeTab is the size of Tab. The attribute n represents the number of elements added to the tab. When the tab is empty n is equal to 0.The constructor University(sizeTab) will initialize the different attributes and allocate the memory to the array Tab.addPerson(p:Person) will add the new person to Tab. The method printAll() will print all the information of the Persons inside Tab.Write the main method. Create three Teacher and three Student and add them to University Object and print them all.
- Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food.
