Question

Even i call this() paramerterised constuctor in my class, Is super class super() parameter less constuctor invokes?
I have excuted the following program. And result will be as follows:
Grandparent() constructor
Parent 25 constructor
Parent() constructor
Child() constructor
The program is below:
class ConstructorChain {
public static void main(String[] args) {
Child c = new Child();
class Child extends Parent {
Child() {
System.out.println("Child() constructor");
class Parent extends Grandparent {
Parent() {
this(25);
System.out.println("Parent() constructor");
Parent(int x) {
System.out.println("Parent(" + x + ") constructor");
class Grandparent {
Grandparent() {
System.out.println("Grandparent() constructor");
for this my excepected answer is
Parent 25 constructor
Parent() constructor
Child() constructor
because in parent class i defined this() constructor so, as my undersatnd is it never call Grand Parent Constructor as it is default parameterless constructor.
please Advise me

Answer 1

You can't initialize a class without it's super classes constructor being run. So even if you call another constructor (of the same class), the parent classes constructor will still be called.
