Inheritance and constructors example

This is an example of inheritance constructors of classes. The example is described in short below:

  • We have created class A, class B that extends A and CClass that extends B.
  • Each class inherits the constructor of its super class to be initialized.
  • We create a new instance for CClass, using its constructor.
  • Since it inherits B‘s constructor that also inherits A‘s constructor all constructors are called.

Let’s take a look at the code snippet that follows:  

package com.javacodegeeks.snippets.core;

class A {

    A(int i) {

  System.out.println("A constructor");

class B extends A {

    B(int i) {


  System.out.println("B constructor");

public class CClass extends B {

    CClass() {


  System.out.println("CClass constructor");

    public static void main(String[] args) {

  CClass x = new CClass();



A constructor
B constructor
CClass constructor

This was an example of inheritance constructors of classes in Java.
