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 think Alex mentioned that he didn't have a good teacher thus he started these videos to help others. Thank God he is a world class teacher and 196K subs at this point in time speaks louder than words.
Thank you for not only explaining yourself as you go, but also taking the time at the end to go back and explain the process line by line. You are a life saver!

To write into a file, try (PrintWriter pw = new PrintWriter(new FileWriter(file))) { pw.write(“data to append) } catch (IOException e) { // Handle the exception }
It is not a good idea to read and write into the same file, it would be better to create a diff file for writing if you perform read operation simultaneously, and later if needed, files can be merged easily

I swear this video was so helpful to me. i was looking for a more efficient method of scanning these than using a normal scanner method. you explained it in a clear way and easy for me to understand. thanks for saving my weekend :)
man I love your tutorials, currently taking Data Structures and the 1st project looked so overwhelming but this was more than half of it and you explained it really well :)

I spent 3 hours trying to figure out how to do this because my uni lecturer is awful at explaining things and makes everything overly complicated, but then I bumped into this and figured it out within the first 9 minutes.
Definitely giving kudos for the clear and concise tutorial you gave...👍 I can't help but ask, however; Why only how to *read* ? Why not also include/explain a method of *writing* to a new or existing csv file? DISCLAIMER: I realize, full well, that a bigger question would obviously be why they never bought up csv/tsv files the entire time I was earning my bachelor's in this stuff. 🙄
I have been struggling with Java since starting it for the last few weeks and felt like I'd given up because I couldn't get my code to do exactly what you just shown. Thank you so much... you may have just saved me from failing my Assessment :)
Why wouldn't you use the java.nio.file.Files class to read a file (from a Path object) as a String? It's a lot simpler and more readable this way. String[] values = Files.readString(Path.of("Path to file")).split(";"); (might throw an IOException) To get an array of single lines, you could either replace the split(";") with split(" "), get a List of all lines using Files.readAllLines(Path) or even a stream with Files.lines(path), though streams might be a little too advanced for beginners Iterating over the array is also easy: for(var value : values) System.out.println(value);
don't think if this is relevant, but can you make a video about creating a java multiple choice quiz using buttons. I am working on a project similar to this and I need help. Let me know what you think.
Hello there! Learned a lot from you :) Since you touched this topic can you please upload a video on how to take image input like some random application wants our image
thanks a lott these videos help, i am actually trying to make an app for parking since i forget to put parking . Can you help me make the app. this is how the app should work -> read the number see if it matches the number i put. -> read the timing till when the parking ticket lasts for and set alarms before the time provided . I cant find any UA-cam channel that will help me in this problem, if you can please find the time to make a video on this. i would be very grateful thankyouuu soo much once again
Thank you so much...😊🙏 . Just one doubt , Is it possible to search for a particular value,like just one name like "Alex" and the program will print all the corresponding values which we need..?
Hello Alex, I hope you are doing well.I wanna little guide from you..I have understood all the concepts of java but while I am trying for competitive coding I am unable to solve it..can you suggest how to be good at competitive coding

I can't wait for your course. You explain topics better than most people, move at constant pace, and provide great examples.
Thanks :)

You no longer need separate catch statements to catch each individual error. You can just use a vertical pipe to separate types.

my first year lecturer, Alex Lee. thank you so much. this year has been tough :(
4:10 start of buffered reader
8:00 creating a String array to store entries in the line and split lines by commas
You can not imagine how you helped me out with my CS lab. Thank you Alex:)
Fourth!
Alex you rock man this is exactly what I needed to analyze stock data! Are you a mind reader? =]
Lol. Are you taking any Udemy course?
That’s a good point this would be sufficient for that
You've taught me more than my college professor has... lol much love Alex
Go to window -> preferences -> Run/Debug -> Console -> disable "Limit console output" . Now you can see all the output.
I swear this video was so helpful to me. i was looking for a more efficient method of scanning these than using a normal scanner method. you explained it in a clear way and easy for me to understand. thanks for saving my weekend :)
Thank you so much for this super useful video! this saved my butt with my assignment haha
If I could I'd reference Alex only in assignments cause this is so helpful
man I love your tutorials, currently taking Data Structures and the 1st project looked so overwhelming but this was more than half of it and you explained it really well :)
Same lol, we may have the same prof.

Just what i needed today!
Thank you man!!
Thank you soo much it was exactly what I was looking for 2 days..
You, my guy,the most unrated youtuber ever!
love your tutorial, please keep going, I will watch all your videos
This vid helped me a lot. Thank you Alex
Don't forget to do a close() on the bufferedreader. Best to put it in a Finally{} block following try-catch.
System.out.println(“I love your videos”);
I spent 3 hours trying to figure out how to do this because my uni lecturer is awful at explaining things and makes everything overly complicated, but then I bumped into this and figured it out within the first 9 minutes.
thanks bro, your java content helped me a lot.
Excellent video, thanks Alex.
Alex! Excellent video and good work. You help me a lot in my studies, greetings from Argentina.
your tutorials are easy to follow and fun to watch, thank you!

You are doing a great job, keep it up.
Oh man you're making this so much easier to digest.
MAN I wish I had seen this tutorial about a month ago. I was trying to write a similar program and for the life of me couldn't figure it out
You are a savior 🙏
Best tutorials keep it up!!
making videos so simple gg alex lee liked vid
If you are using Windows and it seems there's an Exception showing up in String path just change the \ backslash to / forward slash
thank you for explaining the try/catch concept in a way I could absorb Alex 😊
thank you it was really helpful
Just leaving a comment so this channel gets on searches
hi alex i love your vids about java but can you pls make a game with the JFrame plss
MC Noob26 Great suggestion!
I hope hé do it this Will be also good for gis vieus because that is much populier as a simpele turtorial

love the video this helped me out so much
could u please make a video on storing datasets into graphical neural networks using java
How come I didn't find your channel earlier 😕. I am amazed man♥️♥️.
You got a new subscriber
This was awesome. diverting from scanner now. thanks💯
This topic is so important sir.
Awesome video dude. Great help.
Very good explanation
Thanks again, Alex.
Thanks so much for you explain what I needed to understand!
Not bad, man. I hate almost all youtubers but it is good
Dude excellent video!
this video is really powering me through a lab, thank you.
You made it sooo easyyy. Thanks ❤
Thank you very much, man, for your videos
Thank you for this video.. This was very well explained...
OMG! you are just the best!!! :D Thank you!
Can you also explain how to read the csv file into two dimensional array?
It is so nice when someone tells without water
Why wouldn't you use the java.nio.file.Files class to read a file (from a Path object) as a String? It's a lot simpler and more readable this way.
String[] values = Files.readString(Path.of("Path to file")).split(";");
(might throw an IOException)
To get an array of single lines, you could either replace the split(";") with split("
"), get a List of all lines using Files.readAllLines(Path) or even a stream with Files.lines(path), though streams might be a little too advanced for beginners
Iterating over the array is also easy:
for(var value : values)
System.out.println(value);
very useful and amazing .
bravo! From Italy!
what if the data already has commas in it? like the address. The what to do??
Thank you very much for this useful tutorial! Just one thing, I didn't catch why we need at 11: String line = "";
Hey Alex is there a way to put a sound track into a java gui program?
You can use InputStream ! but just convert the files to .wav or .au
@@Aratussyitto I will try that! Thank you!
Thanks Alex!!!
can you do the same tutorial for a 2 dimensiol array? Great video tho and very easy to understand
ty so much you are a king
Can we ignore headers in file
hey Alex, is it more common practice to put the while loop inside the try catch statement? or put a try catch inside a while loop?
Thank you!
dude your awesome!
don't think if this is relevant, but can you make a video about creating a java multiple choice quiz using buttons. I am working on a project similar to this and I need help. Let me know what you think.
Please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hello there!
Learned a lot from you :)
Since you touched this topic can you please upload a video on how to take image input like some random application wants our image
nice tutorial
Thank you so much
About how long of someone learning Java would you say should understand this information clearly? Hopefully that made sense
Wait so which part of this is the array? I'm confused
Thank you alex !! from france
THNAKS, you saved mi life.
thanks a lott these videos help, i am actually trying to make an app for parking since i forget to put parking .

You are awesome thanks
hi, how do you sort arrays from the file? Let's say the length of the address from shortest to longest?
I want to know that as well
yo Alax can you pls make a vid on maps and hashmaps in java? I really need it and love your videos mate:)
He made it already
Thank you! You're a lifesaver!
Do you think you could do a "Shortest path algorithm" video?
hi alex
Awesome !
Can you do a vídeo about OCR?
thanks bra, great video
Bro, have you learned programming language by choosing IT course or you learn by yourself😀😀😀♥️♥️
He is a software engineer.
Hi! Great video! How can I attach each comma separated value to a variable rather than naming the value in the print()?
Do you use "WindowBuilder" plugin for eclipse when making GUI's? If so will you make a tutorial?
I read that it was easier to use this plugin in making GUI's
How would you separate a txt file into multiple txt files i.e. student2018.txt, student2019txt etc
why does it not read the titles of each column and instead start on line 2?
