Develop a Java program to manage a photo album through object-oriented programming.
Start by creating a class called PhotoAlbum with a private attribute numPages of type int. Also, include a public method GetNumberOfPages that will return the number of pages in the photo album.
PhotoAlbum
numPages
GetNumberOfPages
The default constructor will create an album with 16 pages. An additional constructor will be provided to specify the desired number of pages for the album.
Additionally, there is a class called SuperPhotoAlbum whose constructor will create an album with 64 pages.
SuperPhotoAlbum
To complement the exercise, create a class AlbumTest that will perform the following actions:
AlbumTest
No input required
16 24 64
public class StudentTeacherTest { public static void main(String[] args) { Person myPerson = new Person(); myPerson.greet(); Student myStudent = new Student(); myStudent.setAge(21); myStudent.greet(); myStudent.showAge(); myStudent.study(); Teacher myTeacher = new Teacher(); myTeacher.setAge(30); myTeacher.greet(); myTeacher.explain(); } } class Person { protected int age; public void greet() { System.out.println("Hello!"); } public void setAge(int n) { age = n; } } class Student extends Person { public void study() { System.out.println("I'm studying"); } public void showAge() { System.out.println("My age is " + age + " years"); } } class Teacher extends Person { public void explain() { System.out.println("I'm explaining"); } }

Create a Java program that requests three names of people from the user and stores them in an array of objects of type Person.
Create a Java program that prompts the user for three names of people and stores them in an array of Person-type objects.
The instanceof operator in Java is used to check if an object is an instance of a specific class, subclass, or implements a specific interface.
Create a new Java project with three classes plus another class to test the logic of the code. The main classes of the program are the following.
Nested and Inner Classes in Java are defined within another class and have access to the members of the containing class, including private members.
Inheritance in Java is one of the fundamental pillars of Object-Oriented Programming (OOP). It provides a mechanism through which a class can inherit properties and behaviors from another class.
Create a Java program to manage a photo book using object-oriented programming.
Create a class called 'Person' with attributes like name, age, and address. Then, create objects of the 'Person' class and initialize their attributes. Implement methods to display and modify these attributes.
An abstract class is a class that cannot be instantiated directly. This means you cannot create objects directly from an abstract class using the new operator.
Create a Java program that represents the following UML class diagram.
Create a Java program that implements an IVehiculo interface with two methods, one for Drive of type void and another for Refuel of type bool that has a parameter of type integer with the amount of gasoline to refuel.
Create a Java program that implements an abstract class Animal that has a Name property of type text and three methods SetName (string name), GetName and Eat.
