This video teaches you how to use Optional class.
In Java, Optional is a container object that may or may not contain a non-null value. It is part of the java.util package, and it was introduced in Java 8 to address problems related to null values and the common NullPointerException.

The Optional class helps make your code more readable and expressive by making the presence or absence of values explicit, thus reducing the risk of errors from unhandled null values.
