I have my java exam in university in 15 days and I was so stressed about it but watching your videos made it so easy to understand Java. Lots of love to you from Stockholm. :)
Great video, loving your channel so far! I want to add for new learners: One of the most important uses of upcasting is when you have an ArrayList, List, LinkedList, etc, and you can make it of type Animal while adding all types of animals like Cats, Dogs and whatever
Or you can have an array as well. Array of chess pieces for instance. And then every chess piece is actually a pawn, knight, bishop, rook, queen or a king but they are all upcasted as chess pieces in the array.
I still had my doubts about this despite having read my textbook and having attended my university lecture about this two times. I don't normally comment but THANKS A TON for explaining this in just 10 minutes! May God bless you 💞
I try to teach my daughter about upcasting and downcasting for 2 weeks with no avail, And she immediately got it after watching this video, Best explanation !
this video is life saver, nobody on internet explained it this way, whenever i read an article or watch a video about up/down casting they just tell you the syntax which is pretty easy, but i never understood the concept of it, why should i use up/down casting? since i already can call each method from it's own object? but finally i found this video although i'm coming from C# background and i could still understand everything he said. Thumbs up for this man!
I remember watching this video a couple of months ago. That was the moment I understood downcasting and upcasting. The book that I was reading explained it so poorly that I wasn't able to understand what was going on, how downcasting and upcasting work. This guy is such a talented teacher, in 10 minutes he perfectly explained a topic which I wasn't able to understand whatsoever.
This vidio survived me from miss understanding. After reading lots of blogs and watch some videos, just your vidio clarified all the concepts and reasons to me🤩
I was taking this online java course and in it they threw in upcasting and down casting while teaching polymorphism without explaining what this casting is. This was such a great explanation!
Love your videos John, I am using them to supplement the course materials in my intermediate java college course. They are extremely helpful for a 52 year old.
OMG ! this video made my day , I have been searching for upcast and downcast for a day , none cleared me , but the example in your video told why we have to use this upcast and downcast , caught my mind , thankyou so much , you are an amazing explainer. and I subscribed your channel , keep posting amazing contents.
You are awesome! I've been searching the answer of this type of code on the internet for a couple of days and even in the stack overflow I couldn't find a satisfactory answer. You made it crystal clear. One more time, Thank you :)
i like c# over java (very different usages), but (don't kill me) javascript over c# for game dev. in unity, even though they dropped it. slower, but easier to write IMO
Thank you so much for explaining these concepts. I'm learning java. I'm new to to your channnel. No one can explain concepts in more simple way other than you. Keep uploading new tutorials.
Yes, he made the concept easy to understand while the book that I was reading made this concept unnecessary hard. Someone posted a sequence from their book which "explains" casting in Java and yeah, you can see how bad the "explanation" is. It is more of a description of casting for people who already understand what casting is and who are experienced in Java then it is an explanation aimed at learners who don't already understand casting and who are Java beginners. People who write such books are talented, it is not easy to make such easy concepts hard to understand, but they manage to do it.
First time RU-vid recommendation worked for me. Came across you video's and haven't stopped watching ever since. Thank you so much, your explanation are unbelievably good and easy to understand.
What a great video! I am reading a book on Java and I didn't understand downcasting, upcasting, instanceof at all until I watched this video. This explanation is so much better than the explanation in my book.
Hey John! Thank you so much for your videos and course on the website its 200% worth it, I was so tired of these Indian accent guys, was barely able to understand anything, but with your explaination I finally get it all!
This saved mee thank you so much!! Been re-reading the notes given by my lecturers and couldn't wrap my head around it. This video made is so easy to understand!
I had the same impression when I learned this a couple of months ago. The book that I was reading explained it so poorly and then I watched this video and suddenly I understood upcasting and downcasting while also wondering how could I ever not understand this.
Thanks a lot! I ended up learning OOP concepts with Java since I made the mistake to start learning programming with Dart... Anyway, very well explained, keep it up!
