How many objects are created due to inheritance in java?

Question

Let\'s say I have three classes:

class A {
    A() {
        // super(); 
        System.out.println(\"class A\");
    }
}
class B extends A {
    B() {
             


        

Answer 1

1. In your Case One object is created

2. while doing the following, this super() will provided by Compiler Implicitly

   class A {
   A() {
       System.out.println("class A");
   }
   }
   class B extends A {
   B() {
       System.out.println("class B");
   }
   }
   class C extends B {
   public static void main(String args[]) {
       C c = new C(); //
   }
   }
   

It is similar to calling a super() inside your methods

    B() {
        super();
        System.out.println("class B");
    }

The super keyword can also be used when a method is overridden in the current class, but you want to invoke the super class method.

super() will makes the all constructors reference to one class. (For easy understanding: Its like all the member functions are comes under a same class.) Its going to call all the constructor methods only.

So its done the work of calling constructor only, so super() will not done any object creation. Its just referring the member functions.
