Hi,
why in this examples the variable r which is in parent used ?
class Q16
{
public static void main(String args[])
{
A a = new B();
a.callme();
System.out.println(a.r);
a.xx();
}
}
class A
{
void callme()
{
System.out.println("A");
}
int r=10;
}
class B extends A
{
public void callme()
{
System.out.println("B");
}
int r=20;
}
output :
B
10
