What is it called when you use object... as a parameter?

Question

I have noticed in Java that you can have a function with object... as a parameter and then method will take any number of objects as a parameter and treat it as an array. What is this called? I have been trying to search for it but it seems ... is ignored by search engines. I seem to remember printf in C does the same thing.

Thanks.
