5 pull in an interface called telescopic that includes two methods: make open and makeInvisible. Both methods should take no parameters and should return a Boolean result. key how a class talent implement this interface. universal interface Visible { public boolean makeVisible (); public boole an makeInvisible (); } A class implementin! g Visible would bug out with public class Icon implements Visible * 5.6Create an interface called videocassette recording machine 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 annul play (); public annul pause (); public void stop (); public void rewind ();...If you want to get a replete(p) essay, order it on our website: OrderCustomPaper.com
