β˜•οΈŽ Exploring Optionals <?> in JAVA 
01.Coding with Light

This option <?> was added in JAVA 8.
The mascot Duke really likes animals.
(It is one of the illustrative ways to better understand the code).
Officially, developers and designers can use images and play with the Duke mascot.
A good book to learn Java is = Effective Java by Joshua Bloch.
The Optional <?> class includes methods that allow you to explicitly address cases where a value is present or absent.

Practical Example = The cat that comes out of the box is an option.
Example the cat.
Helps simplify code and avoid NullPointerException errors.
