I show you exactly how to read and write files in java! ✅ Simply write this code to open the file and get the text from it line by line using a scanner.

The text file I used: textfiles.com/100/captmidn.txt
It's really easy to read and write files in java! First, open the file by creating using File("path/to/file.txt"); then scan through the file line by line using Scanner to read from the file. If you want to write to a new file simply use FileWriter(""path/to/newfile.txt"");
You'll get the hang of reading from files and writing to files in java! They aren't too bad :) To read file line by line and to write a file in java are very similar. There a few quirks like importing the libraries and adding the "Exceptions" but once you get those and the paths right, you should be good to go!

It is hilarious to me that my computer science teacher spent an hour and a half lecturing of files and I didnt understand a single second of it, and then after watching you actually work in java for 7 minutes I understand.

[@MrDemoncrusher]

I've got the same issue man. My uni lecturer is a brilliant programmer, but an absolute garbage teacher. No body in my class is learning, because for first year students he's expecting the output of veteran programmers. If anyone asks for clarification he's very patronising and if anyone challenges him on a topic he cuts them down with his knowledge and makes them question if they're right or wrong. Even when you do the research and know you're 100% right. Sadly this seems to be common place. Very few programmers are good teachers. Most are good at one or the other. Alex *IS* one of the good ones. If Alex was my lecturer I'd actually _want_ to be a programmer. I probably say that because my lecturer has left me so jaded.

Keep up the good work.. You're a lot underrated at the moment

[@pasiaomega3868]

Having watched a ton of java tutorials, I can easily say this video is one of the clearest, efficiently communicated videos out there with a good level of production value. I can't say thank you enough for that! Count me as subscribed...

[@Lightning_Mike]

A friend recently sent my this video and I can quite say that it made my day. Your tutorials are incredibly useful and easy to follow. Thanks and keep up the good work!

[@pepe-yi6bh]

you simply make the best videos about those kind of things. every time i watch them they are super helpful and easy to understand. Ive been really struggeling with programming lately and u saved me so many times! THANK YOU

[@LC-nk5nr]

You have no idea how helpful your videos are, thank you soooo much!!!! You break everything down in such a concise way. My final is tomorrow and just after watching this I feel so much better already. Hats off to you sir

[@joselinherrera7596]

i have a 2 whole books about java and files 2 hours in class 2 videos and still didnt understand files till i saw your video. you so underrated thank you!!!!!

[@lordender_kitty_official]

you know, you've been doing coding tutorials for at least 4+ years at the time i'm writing this comment and all of the videos you make are just crazy at the quality and the way that you explain things to make them seem so simple. i hope you keep doing this for a while and i really think you deserve more subscribers cause you are incredible at this.

[@dansmith9859]

Thank you! This video was very helpful. I felt so dumb not being able to figure out how to do this, but you really made it straight-forward.

[@mohittyagi6694]

this is the only tutorial which really taught me this file reading/saving thing.. man you are a great teacher. its true that anyone can be anyone's teacher.. age doesn't matter. ty man.

Thank you so much. As previously stated, people over teach this waaaayyy too much and make it super confusing, but you made it so simple and I was able to finally finish my project. Thank you!!

[@ronaldringelschwanz8707]

Well he didn't close the scanner. This is not a good idea! And not handling the exceptions is not recommendable either.

[@toriredman8432]

Your videos are helping me in my object oriented programming class four years after you made them! THANK YOU!

[@avishekdhakal8056]

ngl i'm laughing rn I've my exams in a couple days and i literally have no concept in file handling i was going through every available videos in yt and i was getting more and more confused then i stumbled upon this gem thanks mate ..... you just saved me

[@Xerxes17]

When I'm following your videos, I'm in the habit of adding your later code points instead of replacing the earlier content. For this one I found that since the scanner had already reached the end of file printing to the console, when I called the writer the scanner would profile nothing. Since I don't know of a way to reset the scanner to line 0, I figured what I should do is put the scanner process into a new method which returns a string. It worked! But then I noticed that I wasn't using our File file, and then had to think about refactoring: keep the method using a file path string parameter, or change it to take a File object directly? whyNotBoth?.gif, which then got me thinking of method overrides and polymorphism and damn, it's good content. You give the viewer a rock solid example of a feature, which puts them into a strong position to extend upon it as they see fit and integrate it with other things. Top notch!

[@bora_yazilim]

Thats the video I want. Simple and easy to understand. I am doing cs minor right now and our lecturer spent 1hour to teach this topic. I wish you were my lecturer :(
