While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

This is how I reference the file btw:

#

List<RadiationSample> radiationSamples = readFile("7_14_2019.txt");
        int maxCount = findMaxCounts(radiationSamples);
        System.out.println("Max count is : " + maxCount);
        printWithinFiveCountsFromMax(radiationSamples, maxCount);```

#

Thats just a snippet of code ofc but yk

Where is the file? Because it doesn’t appear that you are accessing it in the directory with the current class. Is it in the source folder?

vocal cliff Mar 23, 2023, 5:13 AM

#

Idk how to import the file into IntelliJ

#

I think I did it once let me send that

#

Screen_Shot_2023-03-22_at_10.13.32_PM.png

#

I put it under src

surreal crag Mar 23, 2023, 5:14 AM

#

Ok awesome

vocal cliff Mar 23, 2023, 5:14 AM

#

Is that all I need to do??

#

Wait lemme check if it works or not

surreal crag Mar 23, 2023, 5:15 AM

#

It won’t work since the class files are what are running - which would be found in the ‘out’ folder

#

Depending on how you want to access the file you will have to either give the directory that it is in (like src) or just place it in the same folder as the file that will be running or trying to access that file. The first one will give you more experience since it’s unlikely the file will be in the same place.

vocal cliff Mar 23, 2023, 5:17 AM

#

I'm not reallly following...

surreal crag Mar 23, 2023, 5:17 AM

#

And what does readFile(file name) do? Return a list?

vocal cliff Mar 23, 2023, 5:17 AM

#

Pretty much yeah

surreal crag Mar 23, 2023, 5:19 AM

#

So the .class files are what actually run. The .Java files are just the programming. So when the code executes, it searches for your file with the name “…2019…”. It will look where it is being executed, which will be that out folder (once the file has been compiled)

vocal cliff Mar 23, 2023, 5:20 AM

#

So do I put the .txt file into the out folder?

surreal crag Mar 23, 2023, 5:20 AM

#

Or reference it in the src folder or somewhere else.

vocal cliff Mar 23, 2023, 5:20 AM

#

Reference it?

surreal crag Mar 23, 2023, 5:21 AM

#

What exactly is the readFile() doing? Did you write it?

#

When you pass in the name, you can include a directory as well such as “../out/filename.txt”.

vocal cliff Mar 23, 2023, 5:22 AM

#

My program is supposed to be doing: "Find the maximum number of counts per minute in the file and write all of the data lines to the console that are within 5 counts of the maximum number of counts per minute. (for example, if you find that the maximum number of counts per minute is 50, write out every line that has 45 counts or greater.)"

#

I just sent that lil bit to show what name I was using for the file

vocal cliff Mar 23, 2023, 5:23 AM

#

surreal crag When you pass in the name, you can include a directory as well such as “../out/f...

Just "/out/7_14_2019.txt"?

surreal crag Mar 23, 2023, 5:24 AM

#

Not quite - we’ll need to know what exactly readFile() needs - do you have access to that method?

Do you want to see the code?

surreal crag Mar 23, 2023, 5:26 AM

#

Can you create a gist?

#

I think the Bot gives an option to do so (but I am unsure how)

vocal cliff Mar 23, 2023, 5:26 AM

#

I think there's an option for that yea

#

OH not in the IDE

#

alr let me just copy n paste the code here and see

#

💀 okay I dont have nitro so let me just try to do this

surreal crag Mar 23, 2023, 5:27 AM

#

Oh

#

You know - we could also just try to add “/“ before the file name haha and see if that helps.

vocal cliff Mar 23, 2023, 5:29 AM

#

💀 Same error

#

But the IDE lets me make a GIST thing

#

So ill do that and you can look

#

just give me a sec

#

Ngl

#

I have NO idea how to share it

#

https://gist.github.com/LucifersAwfulCode/0d4a21ddaad95c8458b38b8a299d8168

Gist

stuff

stuff. GitHub Gist: instantly share code, notes, and snippets.

#

HAHA I hope that works

#

Thats my code

#

The file is like

#

56 MB

#

the .txt one

surreal crag Mar 23, 2023, 5:34 AM

#

Ok I see

#

So try and place it in the out folder (in your system not the IDE) and reference it via “./…2019…txt” (with the actual name haha)

vocal cliff Mar 23, 2023, 5:35 AM

#

With a . at the front or no?

#

💀 Im actually so bad at this

#

BOTH dont work

#

💀 aughh

surreal crag Mar 23, 2023, 5:39 AM

#

no its ok - I

#

I'm not doing so hot here either haha

vocal cliff Mar 23, 2023, 5:40 AM

#

💀 I don't know what this IDE wants ong

#

Ive tried so many paths

surreal crag Mar 23, 2023, 5:40 AM

#

Let me play with it for one second

vocal cliff Mar 23, 2023, 5:41 AM

#

Alr

surreal crag Mar 23, 2023, 5:49 AM

#

I got it to work with the full path

#

(I am on windows so):

#

C:\Users\username\IdeaProjects\Rad\out\production\7_14_2019.txt

#

For example

vocal cliff Mar 23, 2023, 5:52 AM

#

surreal crag C:\Users\username\IdeaProjects\Rad\out\production\7_14_2019.txt

💀 Illegal escape character error

surreal crag Mar 23, 2023, 5:52 AM

#

ok so the \ need to be \ if not already

#

oh \

#

oh

#

haha double \

vocal cliff Mar 23, 2023, 5:53 AM

#

OH

#

OK lemme try

#

NOOOOO

#

GODDDDD

#

Saying the file doesnt exist

#

💀

vocal cliff Mar 23, 2023, 5:55 AM

#

surreal crag C:\Users\username\IdeaProjects\Rad\out\production\7_14_2019.txt

How did you find this? Is there any way I can verify im using the right path stuff

#

Were there any steps u took that i might not've

surreal crag Mar 23, 2023, 5:56 AM

#

Right so in the left side window - right click on the text file and (if in IntelliJ) it will give an option like copy absolute path

vocal cliff Mar 23, 2023, 5:57 AM

#

HOLY SHIT

#

IT FUCKIIG. WORKED

#

YES

#

YES

#

OH MY GOD

#

FUCK

#

THANK YOU

#

HOLY SHIT

#

IT WORKS

surreal crag Mar 23, 2023, 5:57 AM

#

haha

vocal cliff Mar 23, 2023, 5:57 AM

#

HELL YEAHHHHH

surreal crag Mar 23, 2023, 5:57 AM

#

ok wait

#

a better way

vocal cliff Mar 23, 2023, 5:57 AM

#

Yea?

surreal crag Mar 23, 2023, 5:58 AM

#

Place this into readFile() in the parenthesis

#

YourClassName.class.getClassLoader().getResource("7_14_2019.txt").getFile()

#

and ensure the file stays in the out file

#

This makes the code slighty more portable

vocal cliff Mar 23, 2023, 5:59 AM

#

ALR ALR

surreal crag Mar 23, 2023, 5:59 AM

#

(Because now its just using a generic way of finding the file via the path versus it being hardcoded in)

vocal cliff Mar 23, 2023, 5:59 AM

#

RadiationSample.class.getClassLoader().getResource("7_14_2019.txt").getFile()

#

for mine?

surreal crag Mar 23, 2023, 5:59 AM

#

yes

vocal cliff Mar 23, 2023, 5:59 AM

#

ALR

#

THANK YOU SO MUCH

#

YOU'RE SO SMART

surreal crag Mar 23, 2023, 6:00 AM

#

hahaha not really

vocal cliff Mar 23, 2023, 6:00 AM

#

I WOULDVE FAILED THIS WITHOUT YOU

#

THANKS SM

#

UR COOL AS HELL

visual rock Mar 23, 2023, 8:57 AM

#

Usually you would put text files under resources

ancient swan Mar 23, 2023, 9:18 AM

#

vocal cliff RadiationSample.class.getClassLoader().getResource("7_14_2019.txt").getFile()

@surreal crag
You shouldn't use getResource but getResourceAsStream
