class Parent {
int i = 100;
void Printme() {
System.out.println("Parent");
}
}
class Child extends Parent {
int i = 10;
void Printme() {
System.out.println("Child");
}
}
public class Class1 {
public static void main (String args[]) {
Parent p = new Child();
System.out.println(p.i);
p.Printme();
}
}
Output is :
100
Child
On which way I can access variable i of the Child class.

In addition to an answer given by R Manivannan, it is worth noting than you can access i in Child class using explicit cast:
System.out.println(((Child)p).i);
