Get will always give us a value which means it will return a value, and we can already intuit that it will work like a return from a function. We will continue using the example of the Book class, and in Java, there is some simple and fast code to enter the get and set methods of a property:

public class Book {
    private String title;
    private String author;
    private String isbn;
    private int pages;
    public Book(String title, String author, String isbn, int pages) {
        this.title = title;
        this.author = author;
        this.isbn = isbn;
        this.pages = pages;
    }
