A mobile app for a library contains a 'Book' object with information about each book. If an app feature needs to display the title of a book, which aspect of the 'Book' object should the feature reference?
A method of the 'Book' object
A newly constructed class
A property of the 'Book' object
A new variable outside the 'Book' object
In object-oriented programming, a property (sometimes called an attribute or field access via getters/setters) stores data that belongs to an object. The book's title would be kept in a property such as title. Methods are behaviors that execute code, classes are blueprints for objects, and an external variable would not be part of the encapsulated data for a specific book object. Therefore, referencing the title property retrieves the information needed for display.
