Passing a method as a parameter

[Raknarg]

I was wondering if it was possible to set a parameter or variable as a method. In turing, for instance, you can do this:

Turing:

var thing : proc x proc hi    put "hi" end hi thing := hi

Or in Python there's a method called reduce whose first argument takes in a function. Is there anything like that in java?

Oh I just discovered you can use "implement" to do sort of the same thing, you define a bunch of classes with one method that is the function you want.

Any other ideas out there?

Right now you can use an anonymous inner class. Once Java joins the future, you can also use lambda functions like in Python.

Well technically speaking I'm not using Java, but something based off of Java (Processing, in case you're curious), so what I stated above works in it but I don't think I can do that
