Very detailed.. Thank you Ratan

[@prabalsaxena5536]

Ratan sir i have a doubt. Why Parent constructor is showing error while declaring it as a parameterize constructor? My program is allowing me to initialize child constructor as parameterize constructor but not Parent. class Parent { { System.out.println(" Parent class instance block"); } Parent(int c) { System.out.println(" Parent class 0-arg const"); } } class Child extends Parent { { System.out.println(" Child class instance block"); } Child(int a) { System.out.println("Child class 1-arg const"); } public static void main(String[] arg) { new Child(10); // not working new Parent(10); // not working } }

Hi Rathan, I am following your videos. Can you explain "Upcasting", "Downcasting" at Inheritance level? Thanks!

[@9039522806]

Can you please explain the following concept Class Animal{} Class Dog{} Class Main{ public static void main(String[] rags){ Animal obj = new Dog(); } So this object creation does what and what is its importance Can you please explain?

[@shaheenshaikh6701]

Why can't we write child class instance block inside main method ??

[@moududhassan3026]

why parent class constructor execute before child class instance block? It should parent Instance block, then child instance, then child constructor to parent constructor(bcz of super), then come back to child constructor again, as you teaches us.

[@kritisaxena1098]

same doubt

[@manojswn94]

super will give the control to parent class,which will execute static block first then instance block (executed during obj creation)then the constructor,then again the parent class will give the control back to child class, then the child class logic will be executed because the control of execution is given first to the parent class(due to super),the logic over there is executed, then once the child class receives the control the logic in child class is executed

[@vivekreddy8551]

same doubt

[@rupakkumar4774]

See.In the last example first of all static blocks of the parent class and child class is executed respectively.During object creation of child class Parent class instance block is executed then, o-argument constructor is executed because of auto-generation of super() in child class constructor.Now control comes in child class and instance blocks and constructors are executed.

[@MubashirAR]

Why would you partially initialize each? The purpose of both constructors and instance blocks is to execute business logic and initialize variables *at the time of object creation* So it does make sense you execute both before moving further

[@dollysai5444]

thanqqq soo much sirrrr........ i am done with inheritance tanqqq soo muchh

[@DurgaSoftwareSolutions]

thank u dolly sam

[@harithaSingidi]

very nice explanation

[@akhileshgupta9659]

Want to ask why do we create object of child class by taking the reference of parent class.parent() p=new child(); And if parent class and child class both are present in different packages or in different files and assume both the files are complied ,and we are executing only child class Will parent class be loaded in memory and static block of parent be executed.
