Question

Acrobat ivan = new Acrobat ("Ivan"); ivan act (); interface CircusPerformer {private String name; public string getperformer (); public void act (); public void entrance (); public void performance (); public void exit ();} class Acrobat implements CircusPerformer {private string name; public Acrobat (string n) {name = n:} public void act () {entrance (); performance (); exit ();} public string getperformer () (return name;) public void entrance () {system.out.printing(name + " parades with performer");) {system.out.printin(name + " flips forward and backwards on trapeze");} public void exit () {System.out.printin (name + " Lands in safety net");}} What is printed as a result of executing the code segment? (A) parades with performers flips forwards and backwards on trapeze lands in safety net (B) Ivan parades with performers Ivan flips forwards and backwards on trapeze Ivan lands in safety net (C) Ivan parades with performers flips forward and backwards on trapeze lands in safety net (D) A compile error message, due to improperly using an attribute in the interface. (E) A compile error message, due to implementing a method that was not declared in the interface.

Explanation / Answer

(1)   In Interface every field is public static final by default and every method is public abstract.

(2)   Statement written as String name = "Tom"; will automatically converts into public static final String name = "Tom";

(3)   But in the given code attribute name is coded as private String name;

(4)   So result of executing the given code segment is:
  
   A Compiler error message, due to improperly using an attribute in the interface.
  

Hence correct option is (D)
