Just want to say thank you for everything. These videos are the entire reason I am passing my classes and all the videos helped me out immensely. After learning Java using other videos you created, using this series Kotlin was way easier for me to understand. For the first time since starting this journey, I feel like I finally understand the concepts and I owe it all to you guys. When I can I will pay it forward and I highly recommend anyone interested in programming use these resources. It makes a huge difference.

Finally somebody who explains the getters and setters in Kotlin

Y'all are true blessings! My finances are not good right now, but when I'm back on track, I will donate regularly. FCC deserves it!

Hi, this course was very useful for me. All begginners aspects of Kotlin syntax throughly explained. Alex with your permission, as the select while part of collections needs more explanation (from 11:49 to 11:53), I want to explain it as I understood, and please correct me if I am wrong: Look to these commands as a while statement. "take while" loop will continue as long as the predicate evaluate to true. As soon as the predicates evaluate to false the processing of the rest of the collection will not be done. So for third example "dropWhile { it.length == 3 }" means to start from start of list, one.length == 3 is true, then drop it two.length == 3 is true, then drop it three.length == 3 is false, then from here include the remaining elements in the result and break the while loop That is why "six" despite having length == 3 is included in the result. I hope this to be helpful

@programmingwithalex.585

Жыл бұрын

Hi, Thank you for your feedback! I'm glad to hear that the course has been useful for you, and I appreciate your effort in explaining the "select while" part of collections. Your understanding is mostly correct, but let me provide a slight correction: In the third example, "dropWhile { it.length == 3 }", the process starts from the beginning of the list. For each element, the predicate "it.length == 3" is checked. If it returns true, the element is dropped and the process continues to the next element. However, as soon as the predicate evaluates to false for the first time, the remaining elements in the collection are included in the result, and the loop is terminated. So, in your example, "one" and "two" are dropped because their lengths are equal to 3. When the predicate evaluates to false for "three" (length is not equal to 3), the remaining elements ("four", "five", and "six") are included in the result. Overall, your explanation is helpful, and you have grasped the main idea of how "dropWhile" works. I hope this clarification is clear, and please feel free to ask if you have any more questions.

Great tutorial!!! You are very good at explaining each topic and making everything well understood.

❤unbelievable just unbelievable ✅13+ hours long course!!! You rock guys😎👍❤

It is an excellent and outstanding source to learn Kotlin. I'm coming from C# background and it is a bit easier for me to understand comparitively to someone who is starting from scratch. But, I'm sure anyone would be able to grasp the logics of each topic with the teacher being so simple and straightforward. The simplicity and avoiding using too much complex terms have surely won my vote on being one of the best source to learn KOTLIN ! Please don't hesitate to follow the whole course. Definitely, you will learn a lot from this resoruce.

Is it worth it or not?

dropwhile works in order, you can think of it as starting a loop from the beginnign of the list, and continuing to drop elements until a condition is met...that is why the six is left in the list. The loop hits 'three', which is !=3 length, then breaks and the six is left in the list because of the break...at least I believe that is what is happening here.

In the binary search chapter, the code on line 19 should be high = mid - 1 then it works successfully for other searched elements.

Thanks for an amazing course!

Thank You for this course. ✨ Love from India.

alex i am very thankful to you becos you provided such cource😘😘😘

Time to binge this, this weekend.

thank you for such detail tutorial on it. I myself have created lots and lots of android applications.

Alex is simply impressive!

for the binary search I think if cmp > 0 means that the mid number is greater than the searchelement. So the search element should be in the left part of the list. So you have to move the "high" back to "mid -1" and not the low

a slight correction: at 7:06:21, you said not when they are compiled on JVM. JVM doesn't compile, it interprets the already compiled byte code.

4:40:36 the line written starting here is redundant to the line above it. It's not showing a different value for each loop, it's displaying the same value twice. If you had set up the second loop(FOR loop) with a different last value, you would have noticed this

Thank you very much for your effort!!! I just have a note here the video could be way shorter if you just cut the time wasting things

Thanks! Chapters would be useful

Thank you Sir...❤

I like this course !

dropWhile() only excludes elements while the condition is being met. Once it is no longer met it will stop executing. That is why it drops "one" and "two" and then "three" no longer meets the condition which is it.length == 3. That is why "six" doesn't get excluded.

Just when I started to learn android development haha you read my mind

thanks for this wonderful course

4:33:18 This code has a flaw.. If the start number is an even number it will skip that number since we have startNumber++ at the start of the loop... Try the same code with startNumber=2 and endNumber=20 .. You will get only 9 as total even number count

Can anyone please tell that currently which version of sdk should we install to follow along this tutorial?

Could it be that the dropWhile function stops executing when the condition is no longer satisfied?

I was literally trying to find solid Kotlin / Android development videos on KZread yesterday, and what do ya know...

please make a spanish version of this course! we need it. ty

For function overloading a better language design would have been to allow multiple type definitions for the same parameter like: fun getMax(a: Int || Double, b: Int || Double) { ... } To me that's much more concise than having to rewrite/copy the whole function just to change the parameter types. Sure you could also cut down on the amount of duplicated code by just converting the passed arguments to that of the original function and making a call to the original function to do all the work, then convert the result back to the desired type for the overload. But that only works if the parameter types in the new overloaded function are compatible with - smaller than - those in the original.

Hey freeCodeCamp you are doing just great but I have a suggestion can you please always give the codes and notes that were written and used in any tutorial. This would help us a lot in many ways.

in 51:45 you mentioned it the values cannot be printed exceddding the max value. but during practice the values greater than maxINT can actually be print...

This is really helpful. Though there is something I'm having trouble with. At time 6:00:27, if you put a capital "A" at "name.lowercase().startsWith( prefix "A"), the program is going to respond with it doesn't start with "a" or "A" Additionally, "println("Age: ${friend.age}")" also works. The reason for printing out "println("Name: ${friend.name}") is lost. Please help clear these up.

Well done

Thanks!
