Once you depend on interfaces only, you're decoupled from the implementation. That means the implementation can vary, and that is a healthy dependency relationship. For example, for testing purposes you can replace a heavy database implementation with a lighter-weight mock implementation. Fortunately, with today's refactoring support you no longer have to come up with an interface up front. You can distill an interface from a concrete class once you have the full insights into a problem. The intended interface is just one 'extract interface' refactoring away. ...
We will talk initially about Serializable interface. This is a marker interface and does not have any methods.
