Nice information.. Thank you Navin

excellent teaching sir. Can you plz add access specifier topic with hands on coding, to show how private, protected and public members are accessed from derived class/outside world. this would cover more core concept of inheritance.

Well done ! Keep on ...

Great tutorial

I think it would help people follow a little better if the constructor with the int parameter also printed out the int in the text line as well.

Thx!!

Sir I have an doubt regarding object creation in inheritance. Is it true that When a object of sub class created object of super class is not created. ?? I find some answers on stackoverflow that parent class uses the memory of child class object to instantiate its constructor. Hence only one object is created.

very helpful

super!!

does java support heirarchical inherit?

sir, can you explain how reference of (super class) can hold the object of (sub class) and the memory allocation while instantiation of sub class.

is any thing in subclass . we can find it in superclass. . ??

How can we call a subclass method without calling the default method of the superclass ?

expalin it if i am using it with multiple inheritance.... java dsnt support multi inheritance but if the mult inheritence wld be ther in java hw the object creation takes place...???

Sir How to differentiate between method and constructor means how we will know which is method n which is constructor. And when how we will know when we have to use constructor or method?

why do I get an error when I don't have a default constructor in parent class but a parameterised constructor and have child class that extends parent class

can you enable subtitled mode please sir ?

Naveen, i could not create "object of super class with memory allocation of subclass"

Sir can an object of sub class and and referance of super class can be created?

Why we cannot inherit a class with the private constructor?

how to stop calling the super();

package javaapplication132; public class JavaApplication132 { public static void main(String[] args) { System.out.println("output 1"); parent var1=new parent(); // executes only constructor of parent class *(i wil create multiple object of same class thats why variable name is var1) System.out.println("output 2"); parent var2=new parent(1); // executes only parametarised constructor of parent class *(i wil create multiple object of same class thats why variable name is var2) System.out.println("output 3"); child var3=new child(); // executes only constructor of child class and also constructor of parent class(which is called super class) because child class is extend of parent class *(i wil create multiple object of same class thats why variable name is var1) System.out.println("output 4"); child var4=new child("pass string value"); // executes only parametarised constructor of child class and also the constructor of parent class(which is called super class) *(i wil create multiple object of same class thats why variable name is var2) } } class parent { public parent() //create constructor of class parent, because constructor name is same as class name { System.out.println("constructor in class parent"); } public parent(int i) //create parametarised constructor of class parent, because constructor name is same as class name { System.out.println("parametarised constructor in class parent"); } } class child extends parent { public child() //create constructor of class parent, because constructor name is same as class name { System.out.println("constructor in class child"); } public child(String i) //create parametarised constructor of class parent, because constructor name is same as class name { System.out.println("parametarised constructor in class child"); } }
