What Is the Role of Optional in Java and How to Use It Properly?

The Optional class in Java helps handle null values safely without null checks.

Using Optional Effectively

Optional allows avoiding NullPointerExceptions by providing a cleaner way to deal with nulls.

Example Code

            Optional name = Optional.ofNullable(null);
            name.ifPresentOrElse(
                System.out::println,
                () -> System.out.println("Name is not present")
            );
            

This example shows how to use Optional for safer null handling in Java.
