Overriding the Object equals Method - Java Override Example - Comparing Objects - APPFICIAL

Please SUBSCRIBE! More programming videos coming soon! ✌️

Hi, I'm taking a java course at my University. This video has cleared things up quite a bit. I just have one question though, I am having trouble understanding why you would need to cast the object into a (Student)? What is the reason for this?

great explanation and easy to follow.

Danke

Thank you, I wish professors explained it this simple.

how to find earlier class link

I thought we used to equals method just because we compare the content instead of the reference.

This was super helpful for me. I was getting confused on how to implement an Override equals method from scratch and this just cleared up all of my questions. Thank you!

Just to make sure I'm not missing something. Since the StudentID field is private, don't you need a public getter to get it from the argument object instead of dotting it? However it works for you.

EDIT: Nevermind, it's because they share the same class. I was thinking that encapsulation worked cross object too but no.

your implementation is wrong if we pass a value which is not an instance of Student we get an error, same if we pass null.

I have a doubt here, On line 13 in student class the condition should be like this right ?? --- > (!this.getname().equals(s.getname())) because the calling Object is b.

These videos are amazing!!! Thank you so much!
