A new hope was born with the Java 8 release that might be the final weapon against the Empire, called the Optional.
Fight against the NullPointerException implementing your own version of the Optional with extra features, called Exceptional.
A fun test that should help you to think outside the box with an interesting narrative. In this challenge you will fight the evil Lord NullPointerException, that is messing with the Java rebel forces causing our attacks fail unpredictably.
A new hope was born with the Java 8 release that might be the final weapon against the Empire, called the Optional. Sadly, the rebel communications about how to use it were lost, so we need to provide support to our brothers.
Debug what are these mysterious errors and use the Optional to get us to our first victory against the Empire. You can change what you consider necessary, except
the classes inside the internal package, to lead us to victory today and in the future. Make sure that these mysterious errors never happen again.
