Hello,

I am new in JAVA/OOP and have a question about using interfaces.
When do you have to use interfaces? I read some information about the use of
interfaces in JAVA/OOP, but I don't  understand the advantage/strength of
interfaces.

Is the ONLY advantage of interfaces having a set of methods (including a
list of parameters)
which you can use (inherit) for different object/classes? An interface does
not have any implementation,
so you have always write implementation code in the class which implements
an interface !!
That's what I understand about interfaces. But till now I don't really
understand the power/strength
of interfaces in OOP design. The only advantage I see is that you have
always the same methodNAMES and
parameterLIST when using interfaces !

Please, can anyone tell me more about it ?

Thank you in advance for your reply.
