Optional classes in Java

Handling null values is a common source of bugs in Java, often leading to NullPointerException. Introduced in Java 8, Optional classes provide a type-safe way to represent nullable values, improving code readability and reliability.

In his tutorial, our software engineer, Nemanja Marić, covers how to create and use Optional in Java, including Optional.of, Optional.ofNullable, and Optional.empty.

Working with Optional classes in Java

In his video, Nemanja explores how Optional works in Java, as well as how to create and use it effectively, and finally, how features like ifPresentOrElse, mapping, filtering, and chaining can help you write cleaner and more expressive code.

He demonstrates best practices for retrieving values, using ifPresentOrElse, and chaining operations with map and filter through practical examples.
