Who is that in the picture to your left

hahahaha, great video. im thinking a method that has both remove/add and index ref at the same time. Shall we cast the list to the diffrent type.Now im wondering what is the performance like for conversion. Thanks for the great video again. Big fan

I've learn a lot of things with this video, however, I find my self having hard time to forget : "sounds very poopie" hahahahaha

Inshort, LinkedList is way better than ArrayList (totally unexpected for me), if memory is not an issue.

Thanks sir

Best way to calculate Fibonacci number is : public static double fibonacci2(double number) { double a = 1 / Math.sqrt(5); double b = Math.pow((1 + Math.sqrt(5)) / 2, number); double c = Math.pow((1 - Math.sqrt(5)) / 2, number); return Math.round(a * (b - c)); }

wow wait im confused.... you wrote String string1 = new String ("hello"); Could you not have just wrote String string1 = "hello"; ??

Who else is watching in 2024

Question Integer a = 100; Integer b = 100; System.out .println( a==b ) The output is true Integer a = 200; Integer b = 200; System.out .println( a==b ) The output is false Why ?

Do you think you can do a video on comparator and comparable in Java?

Really good video. It would be nice if you'd explain why I'd want to write something like "Animal myAnimal = new Dog();". The upcasting need is clear for functions, but less so about having an Animal reference to a Dog object

Wow, John, please give yourself a pat on the back on my behalf 😊. This was hands down the best Java intro i have seen online. Thanks for making this ❤

Great video, thenks

Your teaching style has performance edge, great job! 🕹

This 11 mins video probably saves you HOURS of research on the internet what the keyword Static means, you're the best John! 👏

I am a beginner in Java and even though I don't know that much about Java I could easily understand most of the things in the video. I'm so happy that I came across your channel. Looks like this channel will help me a lot :D

This video is the best explanation for the Java pass by value/reference topic on UA-cam. Subscribed

Fab❤

This deserves an award for being the first perfectly clear guide on generics. I've done many courses and many java certified developer courses that fail to explain exactly how they work. Well done.

Great explanation , wish i knew your yt channel earlier

Best video about this topic I've ever seen!

public static void main(String[] args) { Map<Integer, Integer> memo = new HashMap<>(); int result = fibonacci(5, memo); System.out.println(result); } /** * Calculates the nth Fibonacci number using memoization. * Time Complexity: O(n) where n is the value of the input number. * Space Complexity: O(n) for storing the memoization map and the recursive call stack. */ public static int fibonacci(int num, Map<Integer, Integer> memo) { if (num <= 1){ return num; } if (memo.containsKey(num)) { return memo.get(num); } int res = fibonacci(num - 1, memo) + fibonacci(num - 2, memo); memo.put(num, res); return res; }

bro whar are you, bc you are genius bro

Very good video

really good video

So I'm very shocked because today Chat GPT-4 created this game in 10 seconds, even when I added some extra "easter eggs" like if the user presses "k", they can play a number guessing game. If they win this mini-game, they get an extra move in tic-tac-toe And Chat GPT-4 explained everything clearly. This code is very user-friendly, which is awesome.

I just think it's so ridiculous that you have to pass an Arrays.asList() inside the arrayslist.

Almost perfect video... when you first implement the lambda, you should have removed the Cat object to show the audience you don't need it.

a four hour class i had summerized in 7 minutes. I'm so flabbergasted honestly 😭😭😭😭

You and code bro saved my exam

00:00 Creating and comparing linked lists and array lists in Java 01:31 ArrayList and LinkedList are virtually identical 03:02 ArrayList vs LinkedList in Java 04:38 Linked lists are a chain of nodes with pointers to the next node. 06:09 ArrayList and LinkedList have different ways of storing data. 07:36 Linked lists are better than ArrayLists for adding or removing elements. 09:00 Linked lists are faster for adding and removing elements, while arrays are faster for getting elements at a certain position. 10:25 Choose ArrayList for retrieving specific values, LinkedList for adding/removing elements.

After watching lambdas explained by you i'm not sure if i want to pay 50$ just to give 50$ to someone who's doing it right or to benefit from a hole course given by someone who's doing it right. I only met once someone in your class mate. Ppl like you are in a special class!

He really melted all my doubts about abstract classes and interfaces in only 7 minutes, that's masterclass explaining there

at line 15 in Cata.java, what is public Cat() {catCount ++; }? I know the concept is closure (updating the state of closure), but it doesn't look like a function and it's not a class, although it is capitalized. Also, I'm assuming that this syntax implies execution upon every instance of cat based on the logic of Main.java. What is the concept and syntax called?

Thank you so much 🙏

hi...can i ask you something? does it even make sense to learn programming because of artificial intelligence?

But what if we take first fibonacii term = 0 Here you take zero fibonacii term = 0

This was extremely helpful, thank you so much!

I never understood this topic for years , I am having my interview tmrw this helped me a lot to understand it quickly.KEEP DOING THE GOOD WORK MAN !!!!❤

Thank you so much. This tutorial really helped me to learn the concept

Java still one of best programming language.its stand the test of time

Thx u for multithreading teach. Before a few hours, I didn't understand that but now I watching this video, I totally understand that. this is slayyyyy!!

exteremly essential stuff tnx lad

Is java even still relevant 4 anything nowadays

You nailed it. A crystal clear explanation.

How do you import Gson?

hey someone has a roadmap on this algoritms and in what order should i learn them

and well, neeva doesn't exist anymore.

What a great explanation! Thanks John!

Thanks Java creators for this shot in the leg
