Static and Dynamic Binding

class A{
int i= 10;
void m1(){
System.out.println("This is A");
}
}

class B extends A{
int i = 12;
void m1(){
System.out.println("This is B");
}
}

class Demo{
public static void main(String[] args){
A a1 = new B();
System.out.println(a1.i);
a1.m1();
}
}

Output:

------------------

10

This is B

Summary:

Variable binding is static in java

Method binding is dynamic in java
