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.

Problem with the code not running and instead giving me error

[patent herald]

I think compiler will give you errors, you dont need to run it tho

Check those errors, they should be too clear

[tidal sluice]

wdym by that?

is there something i have to remove?

[patent herald]

are you not getting any compile errors?

for variables?

cause they are not defined inside the class, they are local to functions

so, other functions cant access them

[tidal sluice]

the errors are cannot find symbol for helper

this one from the main file

[patent herald]

which ide u using?

Are both files in same package?

[tidal sluice]

JGrasp

[tidal sluice]

they should be

[patent herald]

Never used JGrasp, but if you dont even make a package, like run in VS Code, it will run

I can see many problems with Helper file tho

[patent herald]

Can you show, project explorer?

[tidal sluice]

how?

idk project explorer

[patent herald]

which shows hierarchy of files, i can say

[tidal sluice]

can you show me wym

[patent herald]

something like that

[tidal sluice]

like this?

[patent herald]

did you save ur helper file??
Try deleting CoinStarMain.class file and run again

[tough plume]

Why are you not using an ide like IntelliJ?

[tidal sluice]

because thats what the majority of ppl use in my school and also professors. and it has a 30 day trial

[tidal sluice]

still an error

[jagged mist]

IntelliJ is completely free

There is a paid version but you won't need that ever

Anyways, the issue here is that CoinStarHelper is not compiled

You can see CoinStarMain has a .class file, but CoinStarHelper doesn't

[tidal sluice]

yeah i see that since it couldnt run the code

[jagged mist]

Try to compile the CoinStartHelper class first

Let's see if that solves it

[tidal sluice]

no it doesnt, it gives me an error where it cannot find symbol

[jagged mist]

Show the error

[jagged mist]

So.. there is a lot of wrong code in your CoinStarHelper

You used a variable named TotalCost but it doesn't exist ( is it a function? because then it needs to be TotalCost()

And more

[tough plume]

btw: https://www.jetbrains.com/idea/download/?section=windows

just scroll down

community is completely free

[tidal sluice]

forgot to change that

[jagged mist]

the rest of the errors is about that the variables you try to print don't exist
numQ, numD, numN and numP

If you fix that and then compile both files again it should work

But the next step needs to be to download a proper IDE like IntelliJ

[jagged mist]

^^

It'll make your life alot easier

[tidal sluice]

would that mean i did not declare them if it doesnt exist?

[patent herald]

even vs code is much better than that -_-

[tough plume]

but wouldnt recommend vsc for java

[jagged mist]

Yes, or maybe they are not in the scope you used them in

For example, if you declare them in an if statement, you can't use them outside of the if statement

public void myFunction(){ // Scope 1
  int first = 0;
  if (something){ // Scope 2
      int second = 0;
      first = 1; // Works
      second = 1; // Works
  }
  first = 2; // Works
  second = 2; // ERROR, that variable doesn't exist in this scope
}

[patent herald]

yeah, me neither lol, but its surely better than jGrasp, Even I use intellij and Eclipse

[tidal sluice]

well, all code is inisde a method, unless i would have to change the order

[jagged mist]

It's up to you to fix it ¯_(ツ)_/¯

It won't compile like this

[jagged mist]

Except if you show the code

[tidal sluice]

this is helper file

but it was before the changes i made

[tidal sluice]

for installation options, would i have to check update path variable?

[jagged mist]

default options work, just click through

[tidal sluice]

what is Project JDK is not defined?

[olive granite]

It doesn't find a jdk and you have to tell it where it is

[tidal sluice]

uhh ive never used this ide b4 so im kinda lost

[jagged mist]

https://www.jetbrains.com/idea/guide/tips/download-jdk/

Just google

jetbrains has a lot of articles on this stuff

[young cedar]

@tidal sluice It's much easier if you follow through what tim suggested, usually IDE's have their own quick guides to set up everything you usually do.
