I love your lessons. When I don't understand something, I usually use your videos. You explain simply, and it sinks in. Thank you.

You explain so good, realy what is important to understand, in comparison to others. I have seen so many videos on Java, they sometimes speak 20minutes, but don^t say what we realy have to know in order to understand, they just talk and do some things, but do not explain why and how is it in general.

This is far more complicated than it needs to be. You don't need to tie the inner class to the outer object like is done here in the main method. [ Outer.Inner obj1 = obj.new Inner(); ] You could just create the object of the inner class like you would any other object, just initialize the Inner class inside the Outer class body. You dont need to create the object for the inner class in the main method. class OuterClass{ int x=10; Innerclass Innerclass1 = new Innerclass(); class InnerClass { int y =5; //code }

Sir can we make inner class as a private and then is it possible to access by using outer class object???

@teluskosupport Жыл бұрын

Yes, an inner class can be declared as private and once you declare an inner class private, it can be accessed from an object of an outer class. And also private members of a class can be accessed using inner class.

here why did you created object of static class 🤔🤔🤔

@rakeshreddy1365 3 жыл бұрын

he did to show the difference to create obj of inner class in static and non static inner class if inner class is static u dont need to create an object of outer class for creating an object of inner class where as if inner class is non static we need to create an object of outer class to create an object of inner class

why the class Outer has no access specifier (like public class Outer)

@teluskosupport Жыл бұрын

The outer class is default public, it can not have access specifier as private or protected. As when we use protected or private modifier to outer class, we can access it within the package and can't access that class outside the package. So, outer class is by default public.

@ravindermacha1233 3 жыл бұрын

As innner class is static why u need to create object to access it.

@teluskosupport Жыл бұрын

It is just created to show you the difference between static and non-static inner class. If inner class is static, you do need to create an object of an outer class to access inner class whereas if inner is non- static, then you have to create an object of outer class to access it.
