Yes, The class which implements an port provides method implementations for each of the abstract methods defined in the interface. 5.

5 take an interface called indubitable that includes two methods: make tangible and makeInvisible. Both methods should take no parameters and should return a Boolean result. advert how a class talent implement this interface. human race interface Visible { public boo lean makeVisible (); public boolean makeInv! isible (); } A class implementing Visible would bug out with public class Icon implements Visible * 5.6Create an interface called videocassette registrar with methods that represent what a video cassette recorder does ( period of play, reside, etc.). Define the method signatures any way you want. Describe how a class might implement this interface. public interface VCR { public forefend play (); public head off pause (); public void stop (); public void rewind ();...If you want to get a replete(p) essay, order it on our website: OrderCustomPaper.com
