Counting keystrokes in programming is like counting letters in a novel - the amount of time put to think of something, to discuss it, takes the vast majority of time. Keystrokes used to write something is irrelevant (especially if you type with more than 2 fingers)

And if the whole arguments boils down to Java not having a var/val keyword - yes, that would be handy; but you would then still need tools to figure out what is the type of val foo = calculateSomething();
