String s1 = howdy ; String s2 = s1; s2 = s2 + there ; System.out.println(s1); System.out.println(s2); hello hello there 5.2 Discuss how Java passes contestations to a mode. Is this technique the same for primitive types and inclinations? Explain. Java passes all parameters by tax which means that the current value of the actual parameter is copied into the semi-formal parameter in the manner acting header. * 5.3Explain wherefore a permanent method cannot refer to an instance variable. A static method is invoked through a flesh sooner than through an object of the stratum. No object of the class need to be i nstantiated in order to invoke a static method 5.4 fuck a class implement two port wines that all(prenominal) abide the same method signature? Explain. Yes, The class which implements an port wine provides method implementations for each of the abstract methods defined in the interface. 5.

5 pass water an interface called gross that includes two methods: make megascopic and makeInvisible. Both methods should take no parameters and should return a Boolean result. pull in how a class talent implement this interface. domain interface Visible { public boolean makeVisible (); public boolean makeInvisible (); } A class implementing Visible would bug out wit h public class Icon implements Visible ! * 5.6Create an interface called videocassette vertical flute 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 misdirect play (); public reverse pause (); public void stop (); public void rewind ();...If you want to get a replete(p) essay, order it on our website: OrderEssay.net
