Why a supplier instead of a manufacturer?

This is a very simple question, but someone here needs to know, so it's easy to get some points here.

In Java 8 in the package java.util.function

are four categories of functional interfaces: Consumer

, Supplier

, Function

and Predicate

. A Function

converts one input to one output. A Predicate

converts input to boolean

.

The signatures for single abstract methods in Consumer

and Supplier

are essentially opposite to each other:

For Consumer<T>

:

void accept(T t)

      

        
        
        
      

    

And for Supplier<T>

:

T get()

      

        
        
        
      

    

Since a Consumer

takes input and returns Supplier

nothing, but takes nothing and returns a value, they feel like opposites. If someone asked me what the opposite is Consumer

, my natural thought would be Producer

like the Producer-Consumer problem.

So my (admittedly stupid) question is: why not Supplier

called Producer

? Is there an obvious reason I am missing?
