class Dog { public static void bark() { System.out.print("woof "); }}class Alsation extends Dog { public static void bark() { }}public class Bark { public static void main(String args[]) { Dog woofer = new Dog(); Dog nipper = new Alsation(); woofer.bark(); nipper.bark(); }}What is the output

public class test08 { public test08(Object o) { System.out.println("Object"); } public test08(double[] dArray) { System.out.println("double array"); } public static void main(String[] args) { new test08(null); } }

What happens when the following code is compiled and run. Select the one correct answer. for(int i = 1; i < 3; i++) for(int j = 3; j >= 1; j--) assert i!=j : i;

1. interface I{ void f1(); // 1 public void f2(); // 2 protected void f3(); // 3 private void f4(); // 4 } which lines generate compile time errors?

class C1 { static interface I { static class C2 { } } public static void main(String a[]) { C1.I.C2 ob1=new C1.I.C2(); System.out.println("object created"); } } What is the result of attempting to compile and run the program?
