programming to an interface

Have you ever written any JDBC code? You "coded to an interface" then. The java.sql package defines interfaces (Connection, Statement etc) that you write your code against, and at runtime you load a specific JDBC driver which provides an actual implementation for those interfaces. But notice that you don't need to know you're using a particular driver when you're actually writing the code. That is "programming to an interface" in a nutshell: it allows you to not worry about the implementation details until later
