Object-Oriented Programming (Please do not use AI) Create a Java program that has the following: Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass. Polymorphism - Show polymorphism by using method overriding and method overloading. Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction. Show examples of the following words: super, this, static, final

Inheritance The more general class is typically known as the parent class, super class, or base class. The more specific class is typically known as the child class, sub class, or derived class. The Java keyword extends allows you to indicate that one class should be the child class of the original parent class. The child will then inherit everything from the parent class, including variables and methods. {0} Online (1) Main.java x Student.java public class Main { 1 2 3 4 5 6 Run V 7 8 9 10 11 12 13 14 } public static void main(String[] args) { /* Person class example */ Person teacher = new Person(); teacher.setName("Laurel"); System.out.println(teacher); } Reid Moseley X Person.java x /* Student class example */ Student student = new Student (); student.setName("Alice"); System.out.println(student); CONSOLE SHELL Name: Laurel Name: Alice Reset to Template Open Desktop
Task Performance A Simple Payroll Program Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance and polymorphism. Software Requirements: Latest version of NetBeans IDE Java Development Kit (JDK) 8 Procedure: 1. Create four (4) Java classes. Name them RunEmployee, Employee, FullTimeEmployee, PartTimeEmployee. The RunEmployee class shall contain the main method and will be used to execute the program. 2. Write a simple payroll program that will display employee's information. Refer to the UML Class Diagram for the names of the variable and method. This should be the sequence of the program upon execution: a. Ask the user to input the name of the employee. а. b. Prompt the user to select between full time and part time by pressing either F (full time) or P (part time). c. If F is pressed, ask the user to type his monthly salary. Then, display his name and monthly salary. С. If P is pressed, ask the user to type his rate (pay) per…
Objectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…
True or False A class can implement more than one interface.
Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming

Java Programming Create "Mammal" class as a parent class and "cat" as a child class Mammal(Superclass) Attributes name Methods move() eat() cat (Subclass) Attributes age Methods dispaly() eat() Override eat method in cat subclass. Print something in methods such as in move method you can print “I can move”. Test the inheritance with creating objects and calling parent and child methods. Create object of a child class by passing arguments to the constructor.
Protection against the accidental modification of class fields is essential.
