Look at the code and resule below and Interpret it
yourself .. :) .. it is pretty easy.

public class A {
public static void staticMethod(){
System.out.println("Static: I print from
A");
}

public void nonStaticMethod(){
System.out.println("Non Static: I print
from A");
}

}

public class B extends A{
public static void staticMethod(){
System.out.println("Static: I print from
B");
}

public void nonStaticMethod(){
System.out.println("Non Static: I print
from B");
}
}

public class Launcher {

public static void main(String[] args) {
A a = new A();
B b = new B();
A obj = new B();

System.out.println("obj instanceof A : " +
(obj instanceof A));
System.out.println("obj instanceof B : " +
(obj instanceof B));

a.staticMethod();
a.nonStaticMethod();

b.staticMethod();
b.nonStaticMethod();

obj.staticMethod();
obj.nonStaticMethod();

}
}

Consol Output:

obj instanceof A : true
obj instanceof B : true
Static: I print from A
Non Static: I print from A
Static: I print from B
Non Static: I print from B
Static: I print from A <--- See the difference here.
Non Static: I print from B <--- See the difference here.
