Good stuff! I am learning Java now and just got through the File I/O section. Last week I was learning exception handling when your video on that came up. Keep it up
We can also have try with resources because the bufferewriter will be closed automatically. This is good because we may forget to close the bufferwriter.
I love how you added in a way to copy files instead of just doing a "hey, we're gonna write to a file."; That technique can be VERY handy in case of accidental deletion of a file.
Expecting you to reach 100k soon! Please keep making such short and specific videos. Maybe a video on CUSTOM THEMES ? like "Custom Dark Theme" , "Default Night Mode" , Custom Brand Color Theme" , etc! Would love a such video
Bro! I thought i was gonna freak out because of my university excercises, but now I am laughing because you showed me how frickin' easy this is :D Thank you so much!
Do you can solve this: Build Application that has three classes (three user data types). Every class has some of attributes and methods to manipulate the objects of these classes. The objects and their data can be saved permanently into Files. Every class have to save in three forms of files: 1. Object Stream. 2. Data Stream. 3. Random Access File Stream. Data can be brought mainly from csv file. Every record consists of multiple fields, and every line has only one record.
Just wondering how you learned Java. I've been kinda self learning for a while. Took a break and I'm kinda having a hard time wrapping my head around some things
nice, thanks for that. However i tried reading from some an excel i created earlier with various columns and rows but i just a lot of binary among other characters. i initially read and wrote to .xls instead of the .txt which worked fine. any ideas?
good quality video, thank you. the only things i would've liked added are how to use bufferedwriter without overwriting the current state of the text file, and how to create a text file just inside the project folder in case it needs to be moved between pcs both of which probably have easy to find solutions online though, so it isnt an issue edit: to anyone with the same questions, you can append instead of overwriting by adding true as a parameter in FileWriter: FileWriter("path", true) and you can write to a file inside the project folder by just typing the file name without a path, like FileWriter("textfile.txt")
Hi, may u answer my question, I am just curious about the try catch parts, what do it gonna do? also why do we have to handle that exception as well as what will happen if we just dont handle the exception?
Helpful thank you. Is there a (simple) way to ADD to a file (eg a logfile) using this approach, rather than have it just overwrite each time. I realise there are other ways it can be done, but this seemed simpler than most of the ways I have foiund so far - hence wondering if there was an option / switch / parameter to say "dont overwrite, just append this on to it". Many thanks.
Excellent stuff!! You solved my problem in 7 mins. Also can pls explain how can I limit the number of characters in a particular cell of a csv file. For example upto 2000. Please help.
how do I send it to a folder that no one else will likely have? I tried making a folder in my C: drive to send it to but no one else will likely have that folder.
Never put blank or return; in catch block when you use try-catch. You can't know where the error has occured when the project is too large. That's the bad practice!
intern jobs or junior dev jobs for the government are easy to get. Depending on where you live the government is looking for lots of people as developers. It's a great place to start.
what is it called with how his bw.write(str:) like it's showing you your method/function is a string. I notice that in all his videos that it tells you what it is.
The code of #2:46 gave the error. Instead, I have to modify the code as below to run without error. Can anyone explain to me why? import java.io.*; class Main { public static void main(String[] args) { try { BufferedWriter bw = new BufferedWriter(new FileWriter("F:\\JAVA\\InputOutput\\output.txt")); bw.write("karen"); bw.write("\t chad"); bw.write("\t becky"); bw.close(); } catch(Exception e) { return; } } }
javascript is good but for its more advanced stuff, including asyncronous coding and such will kinda get confusing when you get to it versus python being a lot more straight forward and easier to learn. I would say learn all the core basics of Python and then get into some JS. Personally, though, I believe learning C++ and Java is best because you will learn proper coding practices and logic for how higher level languages like python and JS work without the verbosity of types, memory management etc. in the lower level languages. Short answer: Python lol
@@yousefalzeer7265 no problem! Just don't get discouraged. Whatever you start with, it'll take hard work regardless, but it is not as hard as many make it out to be! Just trust the process.

Keep it up
Really really helpful. Loved the clarity and simplicity of your content. Please keep posting 🙌🏼
Your video quality is top notch.
The sound is crispy clear too
Keep up the good work, this video was helpful!
Cheers!
Thank you!

This is a great video. Voice tone, editing, it's perfect man thank you.
I am learning Java since a year now, and this is the best channel across youtube.
thank you so much! They didn't really explain this at the java lecture, so your video was very helpful!

Clear and concise example of file reader/writer. Thank you.
Really good as it is to the point and you were easy to understand. Thanks.
I've found this video useful because you give a solution to a common problem by easy and clear way
that was the most useful video about file i/o on youtube for me. thanks
maaan
I'm taking Java now and I'm so thankful for this video!
Thank you for getting me started on java io
Hey! Awesome video! Could you do a video about your environment setup for coding in java. What IDE do you use/prefer? Maven or Gradle? etc.
Very clear, now I understand. Thank you so much!
Great video. Thank you! 🙌🏾
Great video man! Keep up the good work
how easy this video is!!! Thankyou for sweet explanation XD
Thanks for the great explanation.
Just amazing in easiest way, thank you 👍
Easy to follow. Great content.
I need this for an application to write its log to a file. Thank you so much!
Thanks, was really helpful!😀
Damn you made this look very easy. Thanks mate
thank you coach!
Great video. Many thanks.
worked great thanks

My men love u, U have explained it beautifully.
Thank you sir! If I want for example couple of users to enter their Names how not to override the first name with the second name, etc etc?
nice, thanks for that. However i tried reading from some an excel i created earlier with various columns and rows but i just a lot of binary among other characters. i initially read and wrote to .xls instead of the .txt which worked fine. any ideas?
Well done thumbs up
Nice tutorial!
Which application have you used for programming in this video?
Thanks for the video, i sleep early tonight
good quality video, thank you.
the only things i would've liked added are how to use bufferedwriter without overwriting the current state of the text file, and how to create a text file just inside the project folder in case it needs to be moved between pcs
both of which probably have easy to find solutions online though, so it isnt an issue
edit:
to anyone with the same questions, you can append instead of overwriting by adding true as a parameter in FileWriter: FileWriter("path", true)
and you can write to a file inside the project folder by just typing the file name without a path, like FileWriter("textfile.txt")

What we should do if we need to edit some information in the saved file without losing the other data?
Thanks alot
Sir, i want to ask you how to create an object like for example Class Student in file io ?
Sick video, we were given shit content on this in college and this will help me out with the assignment lol.
how to check if the words in a text file Palindromes are or not?
what str. in bw.write line? even without it will work?
Thankss
How about integer in Bufferwriter?
i don't get why do we need to open a file and write on it are we writing on outer file not ours or my own file
?
Id love to see how you handle server side receiving post requests from a video upload.
How do you print out every line in reverse alphabetical order?
It Created the file and wrote too, but unable to read the code in IDE by second code
I was wandering how do I create a file where the USER can write in it?

@@giangnguyenbang8073 If you're teaching to newbies-such as in this video-, then that is a profoundly horrible excuse.
So is someone gonna give an example for what a beginner should wright? Like I would really like to know as a beginner.
@@DueSouthWests What I said (Knowing the consequences!) is what all beginners should know about!!! Just listen to understand but not to reply.
can we write and read from a text file in a single java file?
thanks sir
Can you please discuss how to find jobs as a Java developer (assuming 0 experience)?
intern jobs or junior dev jobs for the government are easy to get. Depending on where you live the government is looking for lots of people as developers. It's a great place to start.
Which platform do you use?
I typed exactly what you typed here and I got an error "fileName cannot be resolved to a variable"
Amazing video but Is it the same for Mac?
I wish my assignments were as simple as this 😪
so buffered readers and writers are restricted to only one functionality (method)?
what if I wanted to print a specific line from a file? can anyone help?
very good. i like txt file. i write many thing like about the world and about dogs and cats in the file. i write very good information in the file.
What is the meaning of str ?
how can i code a bar chart in java
When My mentor told me we were doing FILE i/o i was kinda scared lmao but it is way easier that what I thought
is it possible to use this method to make a user password program
what is it called with how his bw.write(str:) like it's showing you your method/function is a string. I notice that in all his videos that it tells you what it is.
nevermind that's not it :/
my text is in the same line even when i write
Append to the file?
just wow
Great video! great quality! great explanation! 👏 but I think most of us enjoy watching non-coding related videos more😄
But you didn't cover how to read from excel files using java.io.*;
The code of #2:46 gave the error.
Instead, I have to modify the code as below to run without error.
Can anyone explain to me why?
import java.io.*;
class Main {
public static void main(String[] args) {
try {
BufferedWriter bw = new BufferedWriter(new FileWriter("F:\\JAVA\\InputOutput\\output.txt"));
bw.write("karen");
bw.write("\t chad");
bw.write("\t becky");
bw.close();
}
catch(Exception e) {
return;
}
}
}
Maybe you wrote the absolute path starting at the F drive rather than the C drive?
Karen, Chad and Becky LMAO
i will start to learn cooding soon
so what should i learn first
python
or
javascript
javascript is good but for its more advanced stuff, including asyncronous coding and such will kinda get confusing when you get to it versus python being a lot more straight forward and easier to learn.
