Cоnsider the fоllоwing clаss declаrаtions. public class A { private int x; public A() { x = 0; } public A(int y) { x = y; } // There may be instance variables, constructors, and methods that are not shown. } public class B extends A { private int y; public B() { /* missing code */ } // There may be instance variables, constructors, and methods that are not shown. } Which of the following can be used to replace /* missing code */ so that the statement B temp = new B(); will construct an object of type B and initialize both x and y with 0 ? y = 0 super (0); y = 0; x = 0; y = 0;
Cоnsider the fоllоwing clаss definitions. public clаss Animаl { public void eat() { /* implementation not shown */ } // constructors and other methods not shown } public class Tiger extends Animal { public void roar() { /* implementation not shown */ } // constructors and other methods not shown } Assume that the following declaration appears in a client class. Animal a = new Tiger(); Which of the following statements would compile without error? I. a.eat(); II. a.roar(); III. ((Tiger) a).roar();
