Question

What makes a type different from class and vice versa?

(In the general language-agnostic sense)

Answer 1

Interesting question. I think aku's answer is spot on. Take the java ArrayList class as an example

public class ArrayList extends AbstractList
    implements List, RandomAccess, Cloneable, java.io.Serializable

An instance of the ArrayList class is said to be of type of every superclass it extends and every interface it implements. Therefore, an instance of the ArrayList class has a type ArrayList, RandomAccess, Cloneable, and so forth. In other words, values (or instances) belong to one or more types, classes define what these types are.
