Examine the following piece of code "example.java", and write out the output of the program when executed. Answer the following questions:

 class A { 

 int i=0; void f(){ i=1; }; private void g(){ i=11; }; A() { f(); } A(boolean x) { g(); } 

}

 class B extends A { void f(){ i=9; }; public void g(){ i=99; }; public int h() { return i;} B() { super(); } B(boolean x) { super(x); } 

 public static void main(String[] args) { System.out.println( new B().h() ); 

} System.out.println( new B(true).h() ); }

1) What new file(s) would be generated if you compile example.java?

javac example.java

2) What are the constructors of class B? Are they overloaded or overridden?

3) Run the program by

java B

Did you get the same result as you had anticipated? What happens if you try to run

java A

Can you explain the result?

4) If f( ) of A is defined as private method, what results the program will produce? Can you explain why?

5) If you place the keyword public right in front of the definition of the class B so that you have

 public class B { .... 

can you still compile it by executing javac example.java? If not, explain why.
