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
I learn so much more here than in my actual class that now class is just a place to receive homework and I learn to actually solve the questions here . Thanks Alex !!
Same!! I feel like my teachers just tell me to write the code and don't explain why we actually use it but this video actually explained this so much so thank you Alex! I'll be watching your videos more often now.
Alex, I am currently in a beginners programming class. I have learned more from your videos than my textbook and teacher combined. Thank you for your teachings and for distributing your knowledge, you are a true god send.
My new favorite UA-camr! You always explain everything in such a easy way that even the hardest things become easy after watching your tutorials! You deserve MORE subscribers and likes.
This video was great as I never even knew about switches before I watched it. One thing I would have added was how to make multiple cases output the same thing without having to copy and paste it multiple times. For example, instead of having code like this: switch(objectSize) { case "hammer": System.out.println("Small Object"); break; case "axe": System.out.println("Small Object"); break; case "computer": System.out.println("Medium Object"); break; case "backpack": System.out.println("Medium Object"); break; case "desk": System.out.println("Large Object"); break; case "shelf": System.out.println("Large Object"); break; } You could simplify it like this: switch(objectSize) { case "hammer": case "axe": System.out.println("Small Object"); break; case "computer": case "backpack": System.out.println("Medium Object"); break; case "desk": case "shelf": System.out.println("Large Object"); break; }
I realized that you can also put if-else statements in these cases and default. That's what I did when I can't put less than or equal and greater than or equal statement on cases. I put it inside of an if statement which is inside of a case statement. And it actually work.
Thank you for making life easier by explaining Java. I have been watching your videos for one week and still going! My new year into 2021 is to learn Java with you. I have given up few times trying to learn java, but with your videos, I am self-motivated to sit and watch through your videos without being overwhelmed. So happy I came across your channel. Your truly a Savior! Thank You a million times, and Subscribed. I recommend your Java videos to anyone who is interested. Much love from NYC!
Thank you Alex. I’m trying to learn Software Development in my spare time. I’m a complete beginner. I’ve nearly given up a few times. Your videos are immensity helpful and one of the greatest resources I’ve found. THANK YOU ☺️
thanks dude this helped me a lot! i had a program where you make ur own math test and then you are able to take that test, but you could also do it in different languages. it was 2500 LINES OF CODE. but I cut it down with the switch.
OMG this Saved my life, thank you Sifu Alex Lee! I hope your channel grows prosperous, you're honestly way better at teaching than my professor! I understood everything in your 9min video vs a 3 hour lecture at night.
Thank you so much Alex you are doing great works for the world community. I had trouble understanding JAVA but since I found your videos I'm back studying it again. Thanks a lot again.
This just made me understand switch looping more easier than my classes. Thanks a lot and keep the good work up so students like us can understand stuff easier :)
The reason I came here is because I saw something like: case 1: case 2: break; case 3: case 4: break; and I was wondering exactly how it works. Seems to me like this could be used to replace endless OR operators in your if/else statements because it will do something for 1 or 2 and something else for 3 or 4, right?
First off u r a great teacher. Second off I have a project that uses switch case to remove the vowels in a scanner but I keep getting an error because I compare an integer to a string. So I can't get it to work. I can probably ask my teacher but I was wondering if u could make something like this as a topic for a video. Thanks in advance.
How would you make it possible to also add the integer "1" as a command for System.out.println("Loads file"); in this switch case below? System.out.print("Name the command: "); String command = input.nextLine(); switch (command) { case "load file": System.out.println("Loads file"); break;
Thanks, can you set multiple values for the same output, say in your last example you want to print out "small dog" if the value matches "pomeranian", "pug", "beagle" would it look something like switch(dog) { case "pomeranian, pug, beagle": System.out.println("small dog"); break; ##etc## } or would the syntax be: case "pomeranian", "pug", "beagle"
Do switch case statements only work for == operators and equals() methods? Like is there a wya to implement the , and other comparative operators for integers?
I have a question Is it possible to display in case 2 when inputted in case 1 switch case. EXAMPLE: if in case 1 I ask to write the value of a=2,b=3; then in case 2 it should come a+b=5;
Hey Firstly Congrats on 13.5k subs! Great effort man. Secondly I created an input based program with this where Pomeranian or Great Dane would have to be inputed by the user but in Great Dane even though I typed it correctly, it still gave default output and I think it is because of the space between The word 'great' and 'dane' so is there any way to fix this?
That's a great question! You're absolutely right, scan.next() gets until the first space. So to fix it, use scan.nextLine() which gets until the first newline/"enter"
I didn't understand the logic between the switch and if-else? There is only the reason for code readability? Or anything else. please explain in detail. Thank you.

hahahahahhaha SAAAMEE free days are good days cus i actually learn more on my own
Just started coding bootcamp and my teacher is doing the same thing!
Great!

Yes you are saying the truth
Broooo in less than 10 minutes Alex explained switch statements better than my professor who took like a whole lecture to explain it.
I am so proud that ur not giving up man. I watch every vid... Thx man u deserve more subs and violence
1cps2 thank you so much! I try my best :)
Violence??
You mean audience or something?
You meant 'audience' I suppose? Bro don't wish Alex bad, he's a cool guy XD
This video was great as I never even knew about switches before I watched it. One thing I would have added was how to make multiple cases output the same thing without having to copy and paste it multiple times.
For example, instead of having code like this:
switch(objectSize) {
case "hammer":
System.out.println("Small Object");
break;
case "axe":
System.out.println("Small Object");
break;
case "computer":
System.out.println("Medium Object");
break;
case "backpack":
System.out.println("Medium Object");
break;
case "desk":
System.out.println("Large Object");
break;
case "shelf":
System.out.println("Large Object");
break;
}
You could simplify it like this:
switch(objectSize) {
case "hammer":
case "axe":
System.out.println("Small Object");
break;
case "computer":
case "backpack":
System.out.println("Medium Object");
break;
case "desk":
case "shelf":
System.out.println("Large Object");
break;
}
I don't know what I would do without you man. Keep up the good work!!!
Thanks for the upload bro. Man, you explained it better than my teacher lol.
DavyD thanks man, I hope you have a great day
Thanks, came for a refresh, you forget sometimes. Good teachers like you are rare

Alex I just want to thank you for making these videos. You have the best content about Java for me.
I'm a first year doing java, thanks a million for all that you do
I am now learning the java from beginning only from your tutorial bro...thanks man...u doing great
I was learning Java on W3Schools and the switch stuff confused me. This video cleared up everything that confused me thanks!
man the keyboard sounds so satisfying. Love it :)

how you doing now? :D
still on track?
this has helped me understand the switch control statements a little more better, thank you for highlighting this.
Thank you very much Alex Lee! i was confused with a tutorial. I found your video, you have helped out alot, thanks again!
Getting me through Uni, Thanks for all the help!!

You explain things very well, i just subscribed I hope your channel grows!
Juan M. Thanks Juan!!
i love you bro i have a test tomorrow and its 11:15 pm and im still confused about switch case its completely clear now thanks so much
Although I am new in this field, as far as I see you are the best. Great job! Please, never give up...
The best person ive found at helping understand java and making it simple. Thank you man
Now I have the confidence to open my assignment on switch. Thanks Bro
Thank you sir alex
You helped me in such a small mistake
I really like that you show a problem then u offer a solution . Thanks
Nice explanation. Finally understood switch statement!
OMG this Saved my life, thank you Sifu Alex Lee! I hope your channel grows prosperous, you're honestly way better at teaching than my professor! I understood everything in your 9min video vs a 3 hour lecture at night.
Thanks, man you saved my midterm.
This was so helpful. I'm currently in an intro to Java case and this helped me so much!!!!!!
Thanks man, your tutorials are short and clear.
your a genius. This helped me so much!!!
Thank you a lot for what u're doing. u are our hero! u really help us as student
I actually understand how to do this. I have test next week and I think I'll get an A because of you!! Thank you so much!
im watching all your videos and it's explaining literally all the lessons im going through
you deserve like a million subs.Thank you.I really appreciate this as one of my lessons
It was really helpful to me sir. Thanks. Greetings from Biafra Land.
Thank you so much Alex you are doing great works for the world community. I had trouble understanding JAVA but since I found your videos I'm back studying it again. Thanks a lot again.
This made so much sense to me , easy to understand, thank you so much !
I love you dude!! Please don't stop teaching! ❤🔥🔥

I'm in love with your videos. Thank you very much Alex for explaining everything in the most simple way
Honestly love the way you explain what your doing in these tutorials. Really good!
Thx for awesome tutorial helped a ton in my exams

The greatest computer teacher of the world
thanks, bro! keep it up! I've always watching your videos.
Hey Alex, nice video btw! I have a question. What keyboard brand are you using? It looks so cool.
thanks alex lee for such a sweet and wonderful explantion. Now i am so clear with java programs :)
you are a very gooooood teacher. you deserve more subscribers
Thanks for this video, very clearly explained.
Bruh thanks you helped me on my last day of the assignment I received from the school🤣🤣🤣
Thank you for the videos! They help a lot in my bootcamp 🙌
alex: "Colons arent used too much in programming"
python devs: "Excuse me, what did u say"
Please keep this up, I subscribed!
Great Explanation thank you for the video!
Your videos are really helpful, thank you :)
Thank you Alex. i really like your tutoring style very simple and clear.
How would you make it possible to also add the integer "1" as a command for System.out.println("Loads file"); in this switch case below?
System.out.print("Name the command: ");
String command = input.nextLine();
switch (command) {
case "load file":
System.out.println("Loads file");
break;
Great Vid; I would prefer “if-statements” and “if” needed convert to “switch- statements” to cleanup or concise the code. IMHO! If that makes sense.
Youve really switched my opinion on the case of switch case, in switchcase I would like to thank you;
break;
The keyboard idea is fantastic...is it purchased as a service, can it bought on amazon? or did you do it yourself?
u ar the best teacher on earth
wow this tutorials is easy to understand as always
very very helpful !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks, can you set multiple values for the same output, say in your last example you want to print out "small dog" if the value matches "pomeranian", "pug", "beagle"
would it look something like
switch(dog) {
case "pomeranian, pug, beagle":
System.out.println("small dog");
break;
##etc##
}
or would the syntax be:
case "pomeranian", "pug", "beagle"
Thanks I really needed this!
Really helpful for my understanding. Thanks
okay,all's that's left is to find a way to have input be used as the thing to selecting things.
Wenn typing System.out.println(....), you can use the shortcut Syso + press ctrl+space + enter
i know, im late to the party tho
Do switch case statements only work for == operators and equals() methods? Like is there a wya to implement the , and other comparative operators for integers?
I have a question
Is it possible to display in case 2 when inputted in case 1 switch case.
EXAMPLE:
if in case 1 I ask to write the value of a=2,b=3;
then in case 2 it should come a+b=5;
thx man it realy helped more ppl should know about this chanel
Thanku bro you help us very much please make more videos I really appreciate you from my heart
very good videos!! i understand better here than in my classes
Hey alex can you use a scanner to get an intager from the user for the switch case?
what if our cases contain conditions i,e; x> 10 or 10
I think you have to use multiple IF constructs in that case
Hi Alex,
Could you please explain about regular expression(Regex) concept in Java.
Thanks.
Another helpful video for me, thank you so much for making this video❤❤❤
thanks so much! to clarify, you wouldn't need a "break" keyword following a default statement at all?
No, b/c it serves like the “else-statement.” The final condition that doesn’t apply! 🙏🏾🙏🏾
Thanks 🙏 for the wonderful teaching, I will be really proud to be your student
Can we call two days at the same time? Like I input 1, 2 and it will input 2 kinds of days like sunday and monday.
great definition and nice concept sir love you and proud on you
thank you sir for making youtube videos 💜 God Bless you
Thanks for the video, it was helpful :)
Hey Firstly Congrats on 13.5k subs! Great effort man.

You got a new subscriber,dude.
Great and simple tutorial
give this man a mil viewers
You’re a great human being thank you so much for your help!
What exactly are the "break" between the cases for?
This was very helpful for me, thank you!!
I didn't understand the logic between the switch and if-else?
There is only the reason for code readability? Or anything else.
please explain in detail.
Thank you.
So its basically-
Switch(variable) and Case(Value of variable or another variable) right?
yeah
me not failing is because of your videos
thank you alex
