Recursion Java Tutorial #69

[@alexlorenlee]

If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h

[@evinhendry3560]

Universities, pay to use websites, overpriced textbooks, Udemy courses, exclusive courses: People have to pay hundreds or thousands of dollars to learn even basic Java and it's going to be several long years of study to even get past the introductory phases. Alex Lee: Hold my beer.

So would you be a patron for him?

[@mrboyban]

Tell me..... Enrolled this so called top 30th best CS universities in the world. So disappointed tubes of money thrown at it and all you get back is self-study. Capitalism just turned to be a piss taken.

[@ninjaninja9954]

This is good as an intro but not good enough for an exam question or interview. You may feel you get it but now write a fibonacci sequence and see if you can do that i bet you can't

[@FunnyDubz1]

You're so enthusiastic and you never make me feel bored while learning how to code! I usually don't comment on videos but you sure deserve it!

[@tommieogrady]

I 've tried and seen a lot of java tutorials both free on utube and others you have to pay for. Without doubt these are the best by a long shot.

[@_________________404]

Well yeah, this tutorial is not bad, but it's definitely made for "java beginners". For example, when the StackOverflow exception appears he saids that "The computer can't handle it" which is wrong because the computer can handle it, it's just the program stack being overflown. Program stack size is the limitation, not the computer hardware..

[@joeatefabdullah4095]

@@_________________404 okay wow, computer genius.... bet you cant explain as good as this guy over here

[@_________________404]

@@joeatefabdullah4095 Well no, I'm not saying that he's wrong. When I was learning about recursion, it was important for me to understand how the program stack works, because it then all makes sense. He ignored the topic of program stack in this video in order to make it more beginner friendly, but I'd say that it's very important to understand how the program stack works if you want to fully understand recursion.

How can it save your exams... If u dont even know that hat are u doing here in this university ?? People are not even working alone by themselves today...

[@midnight4569]

@@ValoFranceClips Everyone learns differently and at different speeds. Some people can figure things out by themselves just fine, and other people learn better when something is explained to them by someone else in a certain way. Just because someone learns differently from you doesn't make them stupid or incapable of becoming a programmer. The fact that they're here trying to learn instead of asking for a classmate's code to turn in is actually a really great sign imo.

Can you use the for statement instead? Btw love your videos

Great explanation bro love you 😘

[@javaprogrammer-org]

When did you start tutorials and JavaFX I am curisously waiting.

[@oliverstivers5967]

So, I noticed that all of the examples in this video could easily be done with a for loop instead. What are the advantages, if any, of using recursion, as opposed to a for loop?

[@ZZetsu]

Alex, do ASMR video with your keyboard. it gave me eargasm

[@nayandeep8810]

dude thank you so much!!!!!!!!

[@valsant4]

by far the most helpul videos. thank you alex for making this so simple :')

public class Main { public static void main(String[] args) { insideA("a method"); } public static void insideA(String string) { System.out.println(string + "being called inside of itself "); insideA("being called inside of itself "); } }

[@GoodGirl880302]

I find your Java tutorials very helpful. I'm sorry you have stopped making them. Wish you the best :)

[@adog6704]

So it’s a more complex loop

[@theresafischer7005]

Hey Alex! I love your tutorials! Because you explain everything from bottom up and tell us WHY you're doing WHAT

[@rahulboby7754]

Instead of doing this: n--; sayHi(n); you could do this: sayHi(n--); basically, decrimenting the value of n while calling the methode at the same time. Have a good day :)

[@tyw__]

Saving me in my Comp Sci 30 class bro. My teacher just gives us assignments with PDFs to read. He doesn't even actually know how to program 😭

[@arianaaa2469]

thanks you really helped me out for my exam! definetly subscribed! greetings from Bavaria, Germany :)

[@stevesalesforcedummy9321]

How do I get it so that a piece of code is repeated UNTIL a desired outcome? For example, if I have a random number generator on a loop (let's say the limit is 10), and I want it to STOP once a 9 is generated.

[@jadesimonson8253]

Reigniting my fire to keep learning to code when I get stuck! Thank you so much for all of these videos!

[@favour5442]

Nice ...... but what happened to your keyboard camera there......I love seeing it

[@DavidBartenstein]

Hi Alex, could you please explain why the recursion stops after hitting the basecase instead of just infinitely printing out "Done!"?... I would think that the method would keep calling itself unless specificly asked to snap out of it?

[@nuelzemudio883]

I always used (n-1) instead of n-- I've never thought of using n-- tbh. It might have been the problem

[@greenleaph5145]

Hmm I see, but wouldn't it be a lot simpler to just use a for loop? Why use recursion instead of a for loop?

[@blueballedtech]

Oh, this is an excellent breakdown of an oftentimes tricky subject for many(like myself).

[@yongfulu8984]

Hello, I have question. I don't see you have a Main class in your project and you can still run your code, but when I run my project like this, my IDE says I need to have a Main class, why is that ?

[@maherwrites8931]

alex when you'll be making videos on data structures???????

[@andrewshatnyy]

This explanation is ok for a simple case. I think the majority of devs get tripped at the Real use cases such as the knapsack problem. The problem where you would consider a result of the recursive call while splitting a decision.

[@joethompson8147]

fantastic explanation of recursion. If you see recursion being taught with "Fibonacci sequence "as the first illustration, forget that and use the 2 examples here.

[@hemanthk2561]

[@aaahhh1180]

Can anybody explain why we need recursion when we can use the "for" loop to achieve the same result?

[@Jonathan-rn6rq]

Apparently is it supposed to be clearer and more intuitive than For Loops, where For Loops involve less memory and faster processing. But from my understanding (limited so far), you can achieve the same thing with either of Recursion or For Loops.
