Please help me with my homework question:
Pick an interface in the JDK, describe the method(s) that interface requires, and describe a good use of it.
Note:
An interfaces includes method(s) without any implementation of it. Interface may also include attribute(s). An interface can extend from another interface. One class can implement one or more interfaces (not that it is a must requirement for a class to implement an interface), and one class can implement the method of the interface in one way, and another class can implement the method of the interface in another way.
