Wenn du mit Java arbeitest, wirst du früher oder später auf das Thema Optional stoßen. Gerade für Einsteiger ist das anfangs oft verwirrend. Warum braucht man das überhaupt? Wieso kann man nicht einfach null verwenden? Und wie geht man richtig damit um? In diesem Beitrag möchte ich dir zeigen,

“#Optionals are so tedious to deal with 😮‍💨”

You know what's more tedious? #NullPointerException‎s

I wonder if it'd work to add a guaranteed non-null pointer to C++ like this:

Update: The gist is now fully compiling code.

Dear Friends of Options,  

My brain (pah!) #partially #works in #instances of #sprouting. I #honour its #capacity by:

- #Random acts of #spurt
- #Forging a head, or even ahead
- Never underestimating advice I have not heard  
- Believe in council  
- It has been solved, somewhere
- The Internet is your friend?
- Walk placidly, like a cat  
- Pirate, no parrot? Shoulder cat, hobble along
- Tea from? Nettles, #mint, peal, spices?
- Work WITH. Shout again, WITH nature
- Does not work, may not be needed
- Know Brain, no gain, Know Citizen Banned

Hope that aids your #optionals
