Question

Acrobat ivan = new Acrobat ("Ivan"); ivan act (); interface Circusperformer {public string getperformer (); public void act (); public void entrance (); public void performance (); public void exit ();} class Acrobat implements CircusPerformer {private String performerName; Public Acrobat (String pN) {performerName = pN;} {entrance (); performance (); exit ();} public void entrance () {System.out.println ("Parades with performers");} public void performance () {System.out.println ("Flips forwards and backwards on trapeze");}} What is printed as a result of executing the code segment? (A) Flips forwards and backwards on trapeze Parades with performers Lands in safety net (B) Ivan Flips forward and backward on trapeze Ivan Parades with performers Ivan Lands in safety net (C) Ivan Flips forwards and backwards on trapeze Parades with performers Lands in safety net (D) A compile error message, due to implementing a method that was not declared in the interface. (E) A compile error message, due to not implementing a method that was declared in the interface. Interfaces and Abstract Classes

Explanation / Answer

Ans) F

Reason:

As we are creating a class named Acrobat by implementing from CircusPerformer interface ,In our implementation class(Acrobat) we must and should provide method bodies for all the methods inside the interface CircusPerformer.

Here in the Implementation class(Acrobat) we didnt provide the method bodies for getPerformer() and exit() methods .So we will get complation error.So that our program will not run unless untill we write the method bodies for all the methods in the interface in the implementation class.
