Core Java With OCJP/SCJP: Innerclass Part- 1||Introduction

[@saurabhpal8048]

Nowerdays teaching has become a very big business but a very few like Durga Sir can be said to be following a noble profession and yes many will say he earns a lot from these videos and he has cut many videos but just think has anyone else provided you this much for free? And if he had to earn he could have earned a lot more by providing only one or two topics as demo here and providing rest in Udemy or live class here he might be getting may be lacks but just imagine if he charged 7k for core java from each student lile in Bangalore he could have earned a lot more than what he earns from KZbin.

[@tharunkumar8430]

Note: Before Java 16, you couldn’t have static methods in non-static inner classes. From Java 16 onwards, static methods are allowed in inner classes, provided they don’t interact with instance variables of the outer class.

We can not declare static methods inside inner class because it is instance of outer class and until outer class object creation we can't create inner object right but static declaration inside inner class doesn't talk about object creation then why we can't declare static inside inner

I can't think of a better lecturer to simplify concepts like this. Sir can you have multiple inner classes in a class or multiple inner interfaces in an interface? Also can you have both inner classes and interfaces in a class?

Thank you sir.

[@shashankkumar1201]

Sir, u told that Inner class and outer class share HAS-A relationship. But according to HAS-A relationship, if container class' object is created then inside the Container object the content object will also be created. But in case of inner classes it is not mandatory that inner class object is created by creating outer class(static inner class) only. Inner class can have separate independent existence and after destroying outer class object the inner class object will not be destroyed(static inner class). So my question is not all types of inner and outer classes share HAS-A relationship.

[@pratikbhardwaj3804]

HAS- A relation is AGGREGATION where inside object is not dependent to parent object existence i.e. class Bank has an class Employee, if Bank is destructed then employee still exist and you are taliking about COMPOSITION where parent -child are strongly dependent to each other

[@jvsnyc]

Someone made a good point but still kind of missed the heart of your confusion. Still watching the video, but most people are going to use the terms "static NESTED class" and "member INNER class" only, especially in modern times. That is, we don't speak of "static INNER class" but use the adjective NESTED if the relationship is static. So INNER class unless we say LOCAL or ANONYMOUS generally means instance member.

[@utsavparashar5104]

Please update videos as per java 1.7 or 1.8 because there are few changes in the concepts which you are teaching in this video.

When i use jdk8u231 for the below code, am not getting error/exception for java Outer$Inner., Please explain. class Outer { public Outer(){ System.out.println("Outer"); } class Inner{ public Inner(){ System.out.println("Inner class"); } } public static void main(String[] args) { System.out.println("Outer class main method"); } } Output java Outer -> Outer class main method java Outer$Inner -> Outer class main method

[@ritikakirtani1574]

inner classes are an implementation of composition? In both the concept, there is no chance of existing other objects if the parent object doesn't exist. So are these concept same if yes then we can achieve the same using override concept as well, can you please explain more ?

As static related declarations are not allowed in Inner class then why it is giving error as NoSuchMethodError:main when we run Inner class without declaring p s v main(String[] args) in it?

[@abhishekpathak8562]

sir, we can access inner class members from static method of outer class by creating instance of outer class firstly, then we create instance of inner class by this way (OuterClass.InnerClass i = o.new Inner();).... now here my ques is that why can't we created object after creating object of outer class by this way in static method of outer class - InnerClass i = new InnerClass();....?????

[@abhishekpathak8562]

instead of (OuterClass.InnerClass i = o.new Inner();).

Great Teacher but If you cant repeat one line atleast 7-10 times consecutively that would be great.This video can easily be just 1 hour long. Rest great analogies good teaching.

[@papipdp123]

This is the class of at least 1000 members, and all are mostly college passout. So to make them understand and make them memorise most of the concepts, he does that. I hope you understand. That is the way of teaching to make the newer people understand in a better way. And he is doing his job in a better way and another reason is students are making notes

[@muvvaanudeepreddy1562]

sir but when one object contains other object ,and the contained object doesnt exist with other object is called composition na,where child class doent exist if there is no parent class.but u ar esaying it as inner class.

[@MarimuthuP]

Innerclasses can have static final constants.

[@_devParty]

That is not correct. You can't have a static declaration in an inner class. You'll end up with a compiler error : "Inner class cannot have static declaration"

Hello Sir, I was trying the inner class example by defining main method inside the inner class, however I did not get any compile time error and I was also able to execute the main method from the inner class itself. I am running this code using java 1.8, so has the way of compiling inner classes in java 8 changed? Thanks in advance.

You will get error only if you don't declare main method in inner class . You have included main method so no error

In older version it used to be so but after 16 we can have static methods inside inner class

[@rishithakur8521]

outer.inner i=o.new inner(); sir explain the above statement. Why do we use outer class reference variable to create inner class object..

[@IgiveyouNONE]

public class A { class B { public void show() { System.out.println("Hi"); } } } class Test { public static void main(String[] args) { A a = new A(); A.B ab = a.new B(); ab.show(); } so outer.inner i = o.new inner() is on me A.B ab = a.newB(); When you want to create an object from an inner class you first need a reference from object from outer class!! Because Class A contains B so you can't(in my case) call the method straight from class A, cause my method it's in class B so i first need to make a object from Class A then make an object from class B and this is the line where i making this a.new B(); here i created the inner object. with the reference ab and i'm calling show after that. I hope you get it, bro.
