    I think it is a way to give a class a type that can be tested for to determine if the class has certain characteristics.

    An example of a marker interface is the Serializable interface. Technically, it doesn't really contain any methods. However, it will tell user classes (particular the Object output stream classes) that an object which implements Serializable can be serialized and deserialized.
