The following method ,creating the object of B that refers to A will call the meth() in Class B.
Question: Class A{
Public void meth(){
}
}
class B extends A{
Public void meth(){
}
public static void main(String args[]){
A a=new B();
a.meth();
}
}
Whenever a subclass needs to refer to its immediate superclass, it can do so by use of the keyword ?super? .

No if you want to really call a method in Derived Class then it is only possible if that method will only be present in Derived Class otherwise you can create direct object of the Derived Class.

To access a method of derived class create object for class B.

B b=new B();
b.meth();

If we access class A 's method meth() will not be called.Subclass B
overrides super class.
to access super class method use the keyword super.

Class A{
Public void meth(){
}
}
class B extends A{
Public void meth(){
super.meth()//to access super class method from subclass (bcoz super and sub
class has the same signature or same method name.
}
public static void main(String args[]){
B b=new B();
b.meth(); both methods in A and B are accessed.
}
}
