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.
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
I know python and finding it really hard to get into java for like couple of years and then i quit on java because there was no resources to learn as easy as it is in python. Then this dude came in, man i do not appreciate anyone because of my ego but u dude u killing it. Your “learn java in 14 minutes” video popped in my feed i watched it with a mindset that how much an idiot one can be who is teaching java in 14 minutes. I watched and kinda liked it. Now here i am watching full course of videos and learning java. U nailed it man. Loved it and I appreciate how easy you made it to understand. I am learning java again and finally i feel i will do a careeer switch into java , thanks to u man
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!!
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!!!
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.
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.
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 🙏🏼
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.
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
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!!
I had six epiphanies in the first four minutes of this video, thank you for teaching me in 12 minutes what my prof couldn't teach me in two weeks of classes!
Man, you really deserve to have over million subscribers. I like your teachings && I hope in the future I'll become like you! Thanks for the teachings! :)
Thankyou sir. I liked the way to teach very detailed and its good that you do recap to make sure every line is clear. Thanks from a student of firstyear college from philippines
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
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.
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...
@@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.
Thank you Alex this video really help to write my first program as beginner package contitionalstatmentsloop; import java.util.Scanner; public class Scannerexp { public static void main(String[] args) { Scanner scan=new Scanner (System.in); System.out.println("inter your first name"); String name=scan.next(); System.out.println("inter your subject"); String subject=scan.next(); System.out.println("inter your exam score"); int examscore= scan.nextInt(); if (examscore >= 90 ) { System.out.println("your Pass and your grade A"); } else if (examscore>=80) { System.out.println("your pass and your grade is B");
} else { System.out.println("your field "); }
System.out.println("Thank you "+" "+name+" "+"yours are subject is = "+ ""+subject+ " "+"your result"+" "+examscore); } }
Alex you are Awesome man!! thank you so much for your videos. i am studying java on a well known site and it is good but i always check youtube videos and you are very consistent on making java Understandable! thanks so much for what you do for us inspiring to get into programming.
Thanks for your vids bud. Learning is great. In the quote bit, why wouldnt you just use String quote = scan.nextLine(); to begin with? Surely that works?
Hey Alex I just wanted to start this comment by saying THANK YOU for this tutorial; you were very clear and concise with your explanation and this helped me out a ton. One quick question: How come you weren't required to close your scanner object by typing "scan.close();" at the end of the method? I just finished working on an assignment using Visual Studio Code; however, it wouldn't run it because I was missing that statement. I am not sure if this is something that varies according to what IDE one might be using, but any clarification would be greatly appreciated!

I just learned more two minutes into your video than a whole week in class. Thanks!
I always used scanner lol but never truly understood what I was doing when I thought about it.
now its crystal clear
*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 :(
We all do bud.
Me too I am vonfused
What is Resource leak "sc" please make this topic video please

public class Scannerexp {
public static void main(String[] args) {

System.out.println("inter your first name");
