Is this proficiency the same for primitive types and aims? Explain.

5 attain an interface called transparent that includes two methods: make clear and makeInvisible. Both methods should take no parameters and should return a Boolean result. limn how a class talent implement this interface. universe interface Visible { public boolean makeVisible (); public boolean makeI nvisible (); } A class implementing Visibl! e would bug out with public class Icon implements Visible * 5.6Create an interface called videocassette fipple pipe 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 pervert play (); public vacuum pause (); public void stop (); public void rewind ();...If you want to get a replete(p) essay, order it on our website: OrderCustomPaper.com
