A queue in java is an object that lets you store data like a line for a restaurant. First in line gets first dibs.
A queue is just a line. People stand in line and get fed in order. Queues in java take the next value in the queue. To take the next value in a java queue, do:
q.poll();
Or look at the next value in the queue by:
q.peek();
This queue java code can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned-by-doing!
I hope you enjoyed this queue in java tutorial! I like to have a nice mix of tutorials and actual projects for you all :)

I learned more in this 7 minute video than my hour and a half lecture. Absolute legend @Alex Lee

[@samueldelosreyes7598]

Seriously hayss

[@jackien404]

could not agree more

[@ariefsetiawan3516]

TRUEEE

[@acetan1074]

man .. 2 weeks of class made my headaches, but you healed me in 7:45 mins .

[@RG-ri4qd]

My teacher probably thinks I've been doing programming my whole life, but I've been learning from this guy for 2 weeks. Thanks man.

[@nozgul3865]

For years I have been running and avoiding java. Alex made it so interesting that I have never concentrated in java for this long in my entire life! Wish he made videos when i was studying

[@youvegotmail9385]

Yall have no idea how lucky you are to have KZbin during college. Google hadn't yet acquired KZbin and it was still Google Videos during my time. I bet you didn't know that.

[@beachwave5705]

@@youvegotmail9385 no one asked keep complaining

[@celestial1210]

Really appreciate for making theses videos!! It really helps me a lot in understanding Java!! You make my studies a lot easier!! Looking forward to your upcoming videos!!! Thank you very much, Alex!!

[@alexlorenlee]

Twitch.tv/theadolph that’s awesome, no problem!

[@raboija]

I have been watching your videos all night, so simple and doesn't come out as scripted I love how u sometimes make mistakes and then solve your way through it help us understand better too. Keep up the good quality and thank you for this.

[@abdeselamselami4532]

Thanks a lot Alex, for everyone the short-cut of System.out.println() is type sysout + hit buttons ctrl+space.

[@kyliemun2681]

Thank you, keep it up! You are saving my life during final exams!'

[@flickrplay]

[@Brizzesss]

Thank you so much, I finally understand 3 projects I've been struggling with for weeks through watching a couple of your tutorials, Thank you again!

[@stephanieezat-panah7750]

love the reference to bbq. thank you. queues = fifo, stacks = lifo

[@zaffarismail1508]

Universities should fire those lecturers who spend more time trying to figure out how the projector works and hire people like Alex. Absolutely Amazing Video!

[@anweshapatra6682]

I like your videos a lot it's soo compact and simple to understand with day to day life examples, just makes it soo easy

[@helliboi]

These videos are honestly the best for java learning ive seen. Thank you so much for helping me learn this language :)

Thanks dude!

[@alexlorenlee]

Oh My God! I am really glad i found you. Literally understanding at the last moment for exam. Keep going! Lots of plauds and love for you..Thanks Bro:)

[@jackmanjls]

Excellent, organized and to the point with extremely useful information. Made something that seemed relatively complicated very easy to understand. I can apply this immediately to my project. Also great notes to use for reference.

[@ikutoh04]

Thank you Alex for making Java Easier to learn!

[@dimitrydenscikov5567]

Thank you Alex for your fundamental work:) Fast and easy - what more could we ask for. Hope you're doing marvelously well with your new trainings. Anywhere in the world you know:)

[@azeejshaik7081]

[@valcmeza]

Loved that BBQ explanation! Thank you Alex.

[@user-ww4er1fl8x]

Single handedly saved me from failing. A true legend.

[@zalikashameem6092]

[@syahril2898]

I suggest you use some drawing/visuals when you story tell cause damn its interesting

[@edoardofiorini8989]

Thanks man, love the way to teach so easily

[@user-cm8en8or1p]

Your videos are helping me so much. Thank you.

[@mohamad877]

what's excatly the difference between HashMap, HashSet, Stack & Queue? they are basically all kinda do the same trick. I'm a lil bit confused on why there's many of them, could you please do a video explaining when to use them excatly, which one is better in which situation & why one is better than another etc. @Alex Lee (Thanks for the hard work man! we really appricate you & your videos)

[@nduduzondlovu8520]

you are perfect bro. Can you please do a video for us on how to create methods enqueue and dequeue in java.

[@chimmypark789]

Thank you so much for this. Really got me understood easily.

[@krishbajaj7550]

This is incredible! Thanks Alex!

[@yoni1991]

You are AMAZING man! Thank You. bro!

[@rosswellbonete7919]

thank you for this video! i really like how you explain things clearly :)) now i understand queues more!

[@karagardner733]

Your real-world explanations really help me learn and remember what I've learned! Thank you keep up the good work!

[@lochanpokharel]

Thanks

[@user-rs2yx6zc8q]

should use enqueue and dequeue. They are the standard way to add and take out from the queue

[@branvinifilms]

Well done, thank you!

[@samuelknightmusic]

So gifted at teaching man! Can you please explain how we'd use a .txt file with a queue?

[@prashanthigali8954]

New subscriber i learnt more things in this small video thank you so much

[@JohnReySilverio]

Thank you, your videos really helped me a lot.

[@professorposh4146]

Can you set a limit to the queue so that only 4 elements can fit at one time?

[@arunkutz]

Thank you for the informative video ... Very helpful 😊

[@madeline182]

I think you can't create instance of Queue like Queueq = new Queue() because Queue is an interface, and you can't make instances of Interfaces- on the other hand we have LinkedList which is class implementing Queue Interface, so there is no comilation error, is that correct?

[@sharulaiman7484]

Awesome explanation! love it Alex

[@srihari795]

thats awesome dudeeeee😍😍

[@z1nc0r3]

Thank you

[@baneous18]

Thank you Alex.. you are the best

[@heyocrane8061]

[@riaria2251]

U r awesome sir thank u so much 💖

[@NatureandSpirit111]

Similar to stack but which is faster and what’s the difference?

[@tabithae3679]

THANK YOU

[@christianmanuel4161]

is it better to use .add instead of .offer??

[@esi2047]

Some heroes dont wear capes, Great Video

[@deli5777]

Good vids for sure, but for my class, I'm implementing Queues interface with a LinkedList class. I think this vid helps with testing though

[@Jonny-op3wr]

Can you explain why you need to use linked list for creating the instance?

[@webworld99]

The way my teacher could’ve explained this the way u did……

[@pluviophile7926]

Godsend. TYSM

[@clausekinncaparida8096]

can i print those letters randomly using the q.toArray method? like for example word Certified, I want to make it EICRTFDIE

[@vladanstarcevic7453]

What is the real difference between Stack, Queue and generally Arrays & ArrayList? I watched all of your tuts but it's still a bit confusing to me @AlexLee? Thanks in advance!

[@clausekinncaparida8096]

could you make a tutorial for priorityqueue in java. I badly need it :(

[@Arien17k]

My uni instead of teaching us how to use the data structures available (and already optimized), we have to build our own.... and here I am anxiously searching YT for help TToTT

[@leannemoli2438]

Thank you!! :))

[@Web-Driver]

Thanks.

[@7evenb]

my question is why is there so many types of lists (lists, queues, arraylists, stacks, hashsets, linkedlists) they all feel so similar and i cant tell the reason why they are all needed

[@harshhwardhanrai3716]

plz we want course for data structure and algorithms and competitive programming in java.

[@akumasdeception]

So a linkedList is a standard queue implementation?

[@stephymacvin1888]

In BlueJ ,It has to be given as import java.util.Queue; import java.util.*; instead of import java.util.Queue; import java.util.LinkedList; WHY is this different?

[@nitesharu1269]

I use intellij idea IDE and typed Queue sampleque and after autocomplete there were like 10+ methods implemented with return type as false. If you explain those it may stand more useful

[@twenty4marc306]

Thx

[@venur8153]

how to implement single queues and double queues using single level inheritance by java program

[@austinneatanante284]

How about for deque?

[@katherinegonzaga8948]

how about entering element? like SOP Enter Number/Words:...

[@julianfgc]

how is this different to stacks?

[@mayarabdelfatah699]

Thank youuu!!!!

[@freemancity2518]

Bravo !
