Inheritance Doubt

[usha raju]

Hi,
When I execute the foll code, the output is 10 & sub.Can anyone please explain?
Thanks in Advance,
Usha.
class A
{
int i = 10;
void method (){ System.out.println ("Super"); }
}
class B extends A
{
int i = 12;
void method () { System.out.println("Sub"); }
}
public class test
{
public static void main (String args[ ])
{
A obj = new B();
System.out.println(obj.i);
obj.method();
}
}

This is because, variables are bound at compile-time and methods are bound at run-time .
When the compiler sees the statement
A Obj = new B();
It binds its variable i at compile-time and will not resolve the method call until execution time
so, you get this ouput!
Hope it is clear!

Oops...This is getting even more confusing !! You are contradicting your own stmt...In the first line you say variables are bound at run-time and methods are bound at compile-time whereas in the next line you say just the reverse thing.
Please make it clear.
Thanks so Much !!

Variables: Compile time
Methods: Run time.
