Java Programming Tutorial - 79 - Creating Files

[brandonpkingking]

Im sick as well... BUDDIES



[ashadow0309]

Yay I'm sick too! Sick Buddies. :]

[Kennyshirts]

I found out why it didn't find anything. The file was in fact created, it just didn't show up in the search because it's an empty file.

So if you're using a Mac, and wonder why a Finder search doesn't find your file, it's because it's empty.

[Kennyshirts]

Doesn't work for me. It tells me that the file is created, however when I search for the file it doesn't find anything. I'm using a Mac.

Can anybody help me with this?

[fredme98]

made a infinite txt file generator.

 bad move

[VirtualPineapple]

could you create a java class file with the code to create another java class file with the code to create another java class file? Fileception O_o

[dani786z]

package file; import java.util.*; public class File { public static void main(String[] args) { final Formatter x; try{ x=new Formatter("c:\\dnai.txt"); System.out.println("yes"); } catch(Exception e){ System.out.println("no"); } } } NOT WORKING Y?????????????///

[Ayplus]

@4:15 Haha, he said crested. . .See i made fun of him :)

[ikemefunaikemefuna]

Please Read!

Formatter has a risk of deleting the contents of your previous file too!!

e :- if you already have a fred.txt in you directory, then all its contents will be formatted!

so always give a new file name :-)

[JKTCGMV13]

make infinite for loop

get infinite txt files

[jordao350]

i love your tutorials man, i have learned a lot from you and i am the best student of gramming in class now, i love you man

[yourock129]

:D



[shreshrej]

you crested a file

[gksalex]

Goodl..

[MusicRevelance]

bucky you dont need to tell in every video to subscribe.. every youtuber that went so far with your tuts is definitely a loyal follower of yours!!!

[autom4]

lol@ Try and catch you later :)

[DrizztII]

I'm confused. Is your name Greg or Bucky? Or Fred?

[DazKins]

@DrizztII His real name is greg his internet name is Bucky

[Wildcherrysoda]

Rofl, "They just had to name it exception cuz they had to be different..."

[DemocraWatch]

After, having tried to expand my program beyond the very basic stuff you showed us in this tutorial, I have come to find that the Formatter utility is pretty bad... You cannot use it to append to files that already exist. You can't even write multiple lines with it. I found the FileReader and FileWriter utilities much more adept at manipulating and reading files.

[Bananapoopman]

Make fun of me bid deal "Ok", you crested a file  :D

[robinbuit]

hear al those grass hoppers, are you casting fom your backyard or something like that? sorry for any broken english btw.

[imtihanahmed]

lol my teacher makes ur videos part of our curriculum.

[anthropamorphic]

EVERYONE THAT IS USING MAC OR LINUX

if you want to make a universal directory that anyone can use use this $USER

what I mean is normally you would do User/alec/Desktop <---- but this doesnt work for anyone else unless there login is alec type it like this User/$USER/Desktop

thumbs this up so others can see

[DreadKyller]

btw, just something, the last video said you can not create files with java.io.File, well, wrong.

if(!(file.exists()){file.creat­eNewFile();}

[haudace]

LOL @"to create that file where you want it, like in a folder or something..." 5:30 xD

[LFSDK]

Every time i try to find some Java help

Nothing works but you :-)

[zldamstr]

YEAH! CREST THOSE FILES BUCKY!!! WHOO!! YOU ROCK SIR!!

[xXEffsyXx]

so can you make a folder for the file???

[Sediqwe]

Why not use :

x.createNewFile() ?

[tyebillion]

how do you access the error text when you get an exception?

[jakeywakey27]

"If a user tries to divide by 0"

There is no error for that... The consequence is only death. And possibly the end of the world.

[Shegg77]

@jakeywakey27 It does throw an exception, and there is something to catch it.

[MrBlockersPro]

The grass hoppers and crickets were really helpful also! lol

[Meneltour27]

why does this seem soo much harder than c

there u have FILE* , fopen,fwrite,fread,fseek and all the rest are pretty much  needless why does java have so much stuff

anyway that's just my opinion and it comes from a guy that the first semester of programming in java couldn't even understand it (even the simplest programs)XD

great videos btw ;)

[LPSlasher]

What did I just heard @ 1:20???

"I'll give you guys a quick one too..."

[mihek]

This didn't work right for me. It created a new file, but if i ran the program again it didn't print out the error. Why is that? In on Ubuntu.

[lakers34kb]

@mihek If you run it again, it basically replaces the file again. Check the Date Modified on the file, it would have changed.

[theinquisitor]

They named them exceptions because they're not the same as errors. Errors refer to things like failures caused by running out of memory or a hard disk malfunction. Exceptions are things like trying to run a method on a null object.

[osafiiracit]

crested AHAHHA

[gudenaurock]

They named them Exceptions because the name is longer!, and sound more fancy.

[neilcarberry10]

awesome world of warcraft and age of empires 3 good taste in games!

[Sighduf]

bucky have one or two huge enemies ... they always vote negative ... tell us who is that and we will take care of them :)

[ErichLancaster]

@Sighduf Probbaly some real cocky pro-programmers who're jealous that they don't got the fame!

[ephix231]

He knows hot to make a programming exciting!

[mangopearandapples]

Hey how can you make it so it comes up with a box to tell you where to save it?

[S2h6699]

@mangopearandapples JFileChooser from Swing

[rockyscarlet]

thanx Bucky you save my ass again

[LearnTechTv]

thanks for teaches of how to CREST a file. Next time teach us how to CREATE a file

[erdugen]

video is not working,

please refresh video...

[kyle2120]

sounds dirty....crested...

[thehcd]

just my 2cents:

System.err.println();

is useful for printing errors in your catch exception.

ie. you can ouput errors eventually to error.log and System.out.println() to output.log

[naxjud]

hey idiot input a letter not a number lol

[Fbiman93]

@naxjud, you stole my comment. Now what am I going to say?

BUCKY RULES!!!

[mn7855]

everytime trying to ask question i didn't get what am asking i just need more assistance in this site

[specimon]

thx a lot bucky good stuff !

however and error and an exception are not the same things for java - exceptions can be handled - and errors cant (at least not really properly)

[yasuodances]

thanks for showing us how to crest a file.

lol

:-)

[kincaid87]

Bucky pwns

[realmadridblr]

thnx a ton :)..keep them coming plzzz

[ytgodzilla]

Ahhh! thanks for the exception preview Boss. I'm getting better with mine.  Now I made my own exception and all but now I get a section does not throw and exception error message when I compile. I eagerly await your exception tutorial. Thanks

[mcgarrybd]

I learn more from you than i do from my 10th grade computer science teacher. You are the reason i have an A in that class!

Cheers!

[MrMelonBread]

@mcgarrybd Congrats for going the extra mile

[xlaFax]

@mcgarrybd You're learning java in Grade 10...?

[dtymnn]

@xlaFax - we started since grade 8

[xlaFax]

@dtymnn luckyyyyy

[osafiiracit]

@dtymnn obviously bucky started java programming in kindergarten since he makes lots of grammar mistakes :)))

[68kaspar]

nice, ty Bucky!

[gold1055555]

epic vid >:)

Lol i cant beleive i worked my way through all tutorials already :O
