Inner Class Java Tutorial #81

An inner class in Java, is a class inside of a class, like this:

class ClassOne {

class ClassTwo {

}

}

A class just has variables and methods. But you can also put another class inside and make an inner class (i.e nested class) for readability and maintainability.

I hope you enjoyed this inner classes tutorial!

Hi Alex! I'm prepping for my Java certification as a high school student and have been slowly burning through all your videos this summer. I can't thank you enough for all the free, high quality tutorials you've given all of us and hope you know that what you're doing is really helping us kiddos get into computer science.

I've binge-watched all your videos on java basics and intermediate java and I practiced at the same time and I must say it's the first time I have all these cleared up inside my head. Thank you for everything you did for us! You saved a lot of us :)

Learning your videos have been fun kind of and truly engaging . Would you please organise the Java tutorials into a numbered playlist ? This will help us follow u sequentially! Thank u 🙏🏾

[yaqoobqp]

the link for your course isnt working for me, is it geolocked?

[jonathanc]

I know this is an old video but hopefully you still read comments I was just wondering I tried in my IDE and I was able to do
Outside o = new Outside();
Inside = o.new Inside();
Is it any different from doing it like you at 1:43?
