It certainly doesn't, which is one reason they had to introduce the 
dreadful inner class stuff!

You define a bunch of inner classes(*) that have a single method 
then you can instantiate whichever inner class you need then 
call it's method - yech!

And it's still rubbish because the method names have to be 
the same etc. One reason why for non trivial code C++ often 
works out shorter than Java despite the hype. At least C++ 
includes the concept of method pointers!

(*) Java also allows anonymous inner classes which are directly 
    analagous to Python's lambdas.
