Tip: Using Optional in Java

With Java version 8, there is an option to assign null value to an object of type Optional.

For example:

Optional optionalVar = Optional.ofNullable(null); 
   //Optional.ofNullable() accepts a null value to be passed as parameter

Also, you can use optionalVar.isPresent() to check if the value is present. true is returned if the value is present.
