Uses of Interfaces

Interface uses include the following:

• Declaring methods that one or more classes are

expected to implement

• Determining an object’s programming interface

without revealing the actual body of the class

• Capturing similarities between unrelated classes

without forcing a class relationship

• Simulating multiple inheritance by declaring a class

that implements several interfaces
