Not exactly. I use Guava's Optional frequently when writing Java. It really helps take care of the null problem. It doesn't change the language significantly. However, I really wish it was part of the language instead of a library. Other libraries typically don't return Optionals which forces me to add even more lines of code protecting against nulls.

edit: s/Java/Android Java/, unfortunately the spat between Oracle & Google has prevented most of Java 7 & all of Java 8 from being incorporated into Android Java, which is what I work with on a daily basis.
