Is this proficiency the same for primitive types and object lenss? Explain. Java passes all parameters by assess which means that the current value of the actual parameter is copied into the stately parameter in the system header. * 5.3Explain wherefore a invariable manner cannot refer to an instance variable.

5 form an interface called visual that includes two methods: make palpable and makeInvisible. Both methods should take no parameters and should return a Boolean result. distinguish how a class talent implement this interface. human beings interface Visible { public boolean makeVisible (); public bo olean makeInvisible (); } A class implemen! ting 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 lift play (); public waste pause (); public void stop (); public void rewind ();...If you want to get a replete(p) essay, order it on our website: OrderCustomPaper.com
