confused ????

Posted by saddy on January 22, 2001 at 12:15 PM

Here is a short program

class A
{
int i = 10;
void meth()
{
System.out.println(" i am in A");
}
}

class B extends A
{
int i =20;
void meth()
{
System.out.println(" i am in B ");
}

public static void main(String args[])
{
A a = new B();
System.out.println(" i = "+a.i);
a.meth();
}
}

on executing the above program the output is:
i = 10
i am in B
that is object a is pointing instance variable of A where as invoking methods from class B although instance variable with the same name i.e. i(here) is present in the base class .
can anybody please help me why it is behaving like this.
Thanx in advance
