Could someone help me with this two questions about interface
I couldn't do it :s:
Did you seriously just post a screenshot of your homework and expect somebody to do it for you?
I find it interesting that a lot of folks use the adjective "easy" in the subject line to describe a problem and yet can't answer it themselves. If they don't know the answer how can they possibly know the degree of difficulty of the question?
okey, it's not a homework xD , and @jim it supposed to be easy because i studied the basic only and trying to be pro :o
but thanks anyway <3
My recommendation would be to implement the classes and interfaces. Then try and do what the questions suggest. If it works, then you have your answer. If it doesn't you can try and apply different changes until you arrive at a reasonable answer.
