Read From A File in Java - Way Easier Than You Think - #Shorts

Java File IO (Input/Output) is way easier than you think it is. Reading from a file in Java can be done with just a few lines of code.

File IO is something that's daunting for a new Java learner, but you'll learn how to do file input in Java in less than a minute in this beginner-friendly Java video lesson.

The simplest way to read a text file in Java!

Buffered reader reader equals new reader buffered reader read new file reader reader dot reader file reader dot txt reader

Yup, that's definitely Java!

[redcrafterlppa]

You should close the reader in a finally block or use a try with recourses. This way it won't leak the file handle once an io exception occurs.

[Molotom]

Literally just what I was looking for! Thanks John.

Your shorts are so good?!?! Never thoughts shorts code would work so well!!!

[daveheffler]

😀I am an old C (and ++ and #) programmer and used the File class. It is similar in Java but I also now see Path (and Paths and Files) and other related classes. I am tending to using Path more often but could sure use some guidance in that. Thanks in advance.

[mahanth_ibm]

Wow, this one super simple. Loved it 😍

[aerhansrirangan]

Is there a benefit in using the buffered reader class over the scanner class for reading a file

[jooiey]

bro you are very good at teaching thanks man

[orangeguy]

Isn’t it easier if you use Files.readAllLines?

[aprasath]

Should the close be inside finally? Will the file get closed if there was some exception while reading?

[brennanc]

Don't forget to use finally if you don't use autoclose

[wesosdequeso]

I use the out of the box nio API.
Files.readString
Files.writeString
That should be good enough for beginners to start editing and saving small files like JSONs.

[VuLinhAssassin]

What about the new NIO API in Java 8 and above John?

[Sybfkhevskiha]

Simple way to use IO Apache application

[SaszThe]

What if I want to read file at line no 10

[macstievie]

Why don't you show it with try-with-resources?

[rayNotGlorious]

What about reading from a specific line, like if I wanted to read line 25? Would I have to iterate through the file to get the line I want to read, or is there a function where I can just enter the line I want to read as an argument?

[hano]

Do anyone know the easiest and shortest way to read an excel file? Apache Poi is a pain to me

[ayyubayyyub]

I thought for a second this video will be about how verbose Java can be, you had I am not going to lie 🤥.

[Fly_Nimbus]

And this is why I prefer c++ sometimes
