@sour violet

im trying and i haventused gpt yet

but ye

so i think we get the file as Name-Time-Ingredients-Blankspace-Repeat

so i thought why not make new arraylist every time it hits ""

[sour violet]

what splits the recipe?

[wise pendant]

but my code has error

[wise pendant]

""

line

blank line

[sour violet]

yeah

[wise pendant]

im still thinking lol

recipe search is like the UI

readRecipe is like the try and catch method which uses Recipes class to store read recepies

recipes class has the arraylist of recipes

[sour violet]

yeah

btw you should rename String s to something more understandable, like String recipeFileLocation

[wise pendant]

i mean yea

but its like a one time read so i didnt mind

[sour violet]

ok, but which method is not working?

[wise pendant]

its not the method lemme tell ya

my idea was read the file-than when the new line comes add it to a list of arraylist idk how to say it

like here

but that clearly is dumb logic

you reckon i should start from start?

[sour violet]

no

wait i am thinking of how to explain this to you

[wise pendant]

sure

[sour violet]

wait your Recipes class is confusing me, is private ArrayList<String> recipes; supposed to be a single recipe?

@wise pendant

[wise pendant]

see i was an arraylist of string which holds a single recipe

than add it to the arraylist<arraylist?

so taht every recipe has there own array list

and i can call arraylist[0} and [1] for name and time

[sour violet]

you could do ArrayList<ArrayList<String>> or ArrayList<String[]>

[wise pendant]

like what

oh

you want em to create a list of String arrays

[sour violet]

yeah, but if there are multiple recipes, there is no point of having an arraylist with one recipe, just have an arraylist with all the recipes

whenever you add a new recipe, you add a list or array to the recipe arraylist

[wise pendant]

ye

that is what i am trying

an arraylist with all recepies

the recepies are like

lemmme show

the list will contain this

yo

what if

we add it all until it hit the blank space

than add that to String[] then reset the whole arraylist?

what do you say

[sour violet]

yeah

sounds good

[wise pendant]

lemme try

want me to stream it?

[sour violet]

yes

[sour violet]

if you mean with recipe.add, no

[wise pendant]

oh

lemme tell ya
