Java Scanner Tutorial #14

[@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

Worth to say that you can also use another method instead of using: quote += scan.nextLine(); you can also just type: scan.nextLine(); after previous int age = scan.nextInt(); Also good idea is to use seperate method as: public int getInt() { int number = scan.nextInt(); scan.nextLine(); return number; } and just type for example: int numer = getInt(); Overall great tutorial, im very new to programming myself so will use your videos for sure.

[@Martin-jf4ji]

dude i was having problems with my paper on passing scanners as perimeters thank you very much!

[@Nneoh1]

Alex you're amazing at explaining these things, thanks for helping me understand those basic topics!

[@zorogotbandz1148]

Bro I gotta let you know how much your videos helped me out this semester, the language barrier with my professor made it really difficult to understand things and class, but actually learning a lot more here than in class 😅, but anyway thanks bro your really going save me this semester

[@ruchikakudaskar2736]

*0.06* Scanners aren't taught very well !!! I felt that and i used to think that i was the only one facing issues with scanner input :(

[@tanishqramesh245]

I am in that stage rn😭😭

[@ikouve]

The beginning is so true:"if you like me, you may not have had a great java teacher"!. So true, SO TRUE!!!

[@nazazhdar9697]

im lowkey crying because of how good you explained this, my teacher left it out and said do it on your own, at first i was very scared and wanted to skip it and not do it but then i came across your video and ive never understood anything better than ive undertood this, thank you so muchh!!

[@omarsuleiman9109]

Why was that so much harder for my professor and boss to explain but this makes it seem like it’s kindergarten easy! Thanks so much for breaking it down Barney style! I learned in 12 minutes what I couldn’t for a whole day! Thanks 🙏🏼

[@nazeernero6887]

Hey Alex, I just started in college. I'm doing a Diploma in Network Systems and one of my modules is Java Programming. All my lessons are on ColCampus so I can't physically interact with my educators which is really a challenge, they don't make content as easily understandable as you do, I find myself very frustrated at times not understanding what to do, however I find your content really helpful. Thank you so much.

[@alyst79]

I have been struggling with java so much. thanks a lot for your videos

[@aliobaidi8374]

You are a true savior. I was really confused and you explained everything to me. God bless you.

[@milkonion]

I always used scanner lol but never truly understood what I was doing when I thought about it. now its crystal clear

[@alexandrahulett946]

I just learned more two minutes into your video than a whole week in class. Thanks!

[@jorgerivera7008]

YOU helped my pass my final! Thank you for being so in depth, yet simple! Best tutorial vids!

I don't use JAVA for absolute anything but i came hearn to learn it from time to time just because u are awesome teatcher. srsly. Planning on put your voice on a Lo-fi beat atm.

[@raenamcintosh]

thank you so much. java is so much harder for me than python and this is the only resource getting me through my classes

[@michaellabeltran3807]

School from home is hard, because sometimes we are having trouble with internet connection and I cant often understand my instructor. What I do is I go to your youtube channel and I undertand your video really well and it helps me to answer my profs activities. Thank you so much!!!

[@michaellabeltran3807]

You explain every topic really well , it is easy to understand and i find myself going back to your channel eveyday to learn something new

[@cagla3360]

thank you so much! this is my first year in computer science and my professor doesn't upload any lecture notes to our school's website. I was hopeless about studying before I found your channel.

[@mcjohnbolivar]

this is the lesson that i am looking for, teaching every codes uses. my professor teaching as to code but not teaching as how the code works.

[@adengouled9614]

I'm sure you've heard it before but you're a really good teacher!

[@AleX-cc2dl]

You have excellent teaching skills. Glad I found your channel. While others simply explain what to use and what the result is, you explain why to use it, and thus makes perfect sense in one's head. Thank you!!

[@tell1998]

Thank you for this video. I'm currently taking Java Programming for my online class and it's online only. I work full time and am a college student full time so I have little time to study and fully take it in. I haven't fully read Scanner and was a little confused from it (if I had more time I would fully understand) but being able to watch your video and get a better explanation helped me understand it better. Thank you

[@Neoscarface6342]

I dont know who you are but you may have saved my semester

[@afonnechijindu4378]

Thanks Alex. Your explanation is top notch. Before now I wanted to skip that scanner sh*t but I could now play around with it. Thank you. AC from Nigeria

[@creepycreeper1127]

Why do we have to get the first word with scan.next() and then get the rest of the line with scan.nextLine()? Is there not some way to just get the whole line from the start? It seems like extra work...

[@afifkhaja]

I think you can just use nextLine() by itself

[@MichaelLee-jm7mo]

@@afifkhaja you think? or does it work 100%?

[@afifkhaja]

@@MichaelLee-jm7mo 100%

[@akshaydeogaonkar7120]

@@MichaelLee-jm7mo It doesn't work... Actually, I got in here because of this issue only...

[@jonahosband4534]

@@akshaydeogaonkar7120 the reason he does that is because nextline() takes unused previous inputs as well as the remainder of a string. The previous method he uses is nextInt() which returns an integer value and when he hits enter the nextLine() method would read that previous enter as the input and not take what you want to input because the nextInt() method does not include the enter which is read as a string so therefore if you just used nextLine in that case it would pick up the enter and return a that before you can enter the code. Sorry if that seemed all over the place. I’m a college student self-learning and that’s how my CS friends explained it to me.

[@patrickmyers2888]

These videos are so clutch, thank you so much! I hope you continue to make these, they are super valuable.

[@ravipitta3388]

Great tutorial, Alex! You've earned yourself another happy camper!!

[@AndersJackson]

In Eclipse, use Ctrl-Space when you have typed Scan, and you will get expansion and also imported Scanner in one go. I usually have System.out.print() and not println() to print prompt for telling the user what to enter. Scanner should also be closed before the program exits, which could be done with try-resource. try (Scanner in = new Scanner(System.in)) { String name = in.next(): int age = in.nextInt(); } And you should probably use printf() instead of println()/print() when printing out values. As you have way better control of formating the output. I love how you solve the problem with mixing next() and nextLine(); I will take that with me.

this is the best tutorial for scanner in java. cool, good job now i know how scanner work in java

Thats a very nice tutorial, great job. I want to advice young developers to learn how to put input on a program in order to make it interesting and make their programs more complex. After learning how to put an input in your program i challenge you to try the tutorial i made that is actually a money currency converter
