could anybody help me to find out the answers for these questions

Q)The static modifier is valid for
a) Class declarations
b) Class initialization blocks
c) Local variable declarations

Q)Consider the following code:

1. public class Cat {
2.   int iq;
3.   public Cat ( ) {
4.   }
5.   Cat(int i) { iq = i;}
6. }
7. public class TestIt extends Cat { 
8.   final Cat c = new Cat (6);
9.   public static void main(String[] args ) {
10.    c = new Cat(4);
11.    c.iq = 5;
12.    System.out.println("Cat IQ = " + c.iq);
13.    return;
14.}
15.}

a)5
b) Compiler error, you cannot change a final variable
c) Compiler error, you cannot subclass from Cat
d) 6

(I gave your code sample a little formatting so it would be easier to understand)
Q1) Inner class declarations and class initialization blocks.
Q2) You could just copy this program into a couple of .java files, compile and run...
In my head, I think the answer will be 5.

Hi,
I think i have two findings in your code.
First, the variable c is an instance variable in TestIt and can not be accessed inside a static method like main.
Second, even if we declare/define 'c ' inside main then we encounter the problem "Can't assign a value to a final variable: c"
So, to me, the question looks like a wrong one.
What do you think?
Rgds,

Right on both counts!
