The above statment only works when !=null is called first.
But this is also assuming that the Java compiler will keep the order
this way (otherwhise it does throw a nullpointer exception)


On the other hand, its not a very clean, conservative style.
On a large project like Minecraft, he should be
more careful with such stuff, else it could result in hard to track bugs.
Notch participated several times in the Java4K Contest, sharing
code.
Its really cool so see minimized code, but its not
an approach to take for large-code projects.
