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.

is x declared somewhere?

so x is of type Card

can i see Card class

wait i see a typo, x.condtion instead of x.condition

[delicate ruin]

oh

sugh

sigh

now it says this

[versed maple]

is the field private?

[delicate ruin]

do i just make the condition

public

[versed maple]

oh do you have getters and setters?

[delicate ruin]

yes

[versed maple]

use getter to get values and setter to set values

[versed maple]

and no, ideally you wanna have vars as private

[delicate ruin]

how would i use this

would i just do x.getCondition

[versed maple]

so that it can't be modified by anyone else

[delicate ruin]

makes sense

[versed maple]

x.getCondition()

for ex: even if someone uses your setters to modify a value, you could put a check inside your setters like "check for negative value" only then you allow someone to set value

that's just one way to understand

[delicate ruin]

yea so i need to do something in the other Class

to change the condtion in the Card class

so do i have to make the condition var public

[versed maple]

if you wanna use it in other class, you use getters and setters

since those are public

[delicate ruin]

i want to change its value from another calss

class

[versed maple]

that's cool

i don't see the problem

[delicate ruin]

so to change the value

i dont need to change it to public?

here

[versed maple]

i don't think you read my texts carefully, getters and setters are used to access and modify these vars anywhere you want to

[delicate ruin]

oh

[versed maple]

since these are public and can be used

[delicate ruin]

the setter can be used from another class?

[versed maple]

yes

[delicate ruin]

so im just confused how i would make the setter

[versed maple]

are you using intellij?

or is it vscode

[delicate ruin]

i think i did it

[versed maple]

yes

btw you can generate getters and setters via IDE

i think it's right click inside class-->generate-->getters and setters

then you select your vars

wait not here, inside Card class

nvm it looked like you did it in another class

[delicate ruin]

it is in card calss

lmao

whoops

another question

i need help returning here

[versed maple]

what's the problem?

[delicate ruin]

this is what is retunred

[versed maple]

hmm you may need to generate a toString method for your class

[delicate ruin]

i do what that

[versed maple]

checkout by right clicking inside your card class

right did you already have it

[delicate ruin]

but that returns a string to the method

i need to return a card object

[versed maple]

yea then it only needs to be return oldCard

and just print it inside the sysout

you handled return types like it was supposed to be so no problem there

[delicate ruin]

so it should return the memory location?

[versed maple]

it should return a card object which it did

[delicate ruin]

hmm little odd

but ig its right

[versed maple]

your printing the object ig that's why you are confused, have you tried doing System.out.printf("sold: %s\n", binder[index].getPokemonname())

or if you want all the details fo card then prolly toString method inside sysout

altho i remember reading somewhere that sysout automatically uses toString() method to print out on console but weird dk much about printf

[delicate ruin]

ok

why does this not print the whole string

using

[versed maple]

idk it works for me

output

so ye you don't need toString

[delicate ruin]

its in 2 diffent classe

[versed maple]

sysout automatically takes care of that

[versed maple]

wym?

[delicate ruin]

like the Card

and collection are 2 diffrent

[versed maple]

not sure exactly, seems alright to me, may have to use annotation override on top

[delicate ruin]

where wld i fix that

[versed maple]

on top of your toString() method use annotation override
