STL library vs JCF framework

Question

Why is the STL considered a library, but the JCF a framework? What exactly is it in their respective designs that causes/justifies this distinction? Can you give a code example that illustrates this?

Answer 1

Definition by Martin Fowler:

A library is essentially a set of functions that you can call, these days usually organized into classes. Each call does some work and returns control to the client.

A framework embodies some abstract design, with more behavior built in. In order to use it you need to insert your behavior into various places in the framework either by subclassing or by plugging in your own classes. The framework's code then calls your code at these points.
