#

what is the tablo class?

#

and why do you use an observablelist?

#

and what is urunTablosu

public class tablo {
    private String urunIsmi;
    private String kategori;
    private int fiyat;
    private int BayiID;

    @Override

slender hinge and what is `urunTablosu`

urunTablosu = table id

slender hinge Jan 12, 2023, 9:56 AM

#

its a field

#

what type does it have

mental elbow Jan 12, 2023, 9:57 AM

#

#

I want to transfer the data in .txt to the table

slender hinge Jan 12, 2023, 9:57 AM

#

you do urunTablosu.getItems()

#

what is the urunTablosu field

mental elbow Jan 12, 2023, 9:58 AM

#

private TableView<tablo> urunTablosu;

slender hinge Jan 12, 2023, 9:59 AM

#

does data2 have to be an ObservableList?

mental elbow Jan 12, 2023, 9:59 AM

#

it could be something different

slender hinge Jan 12, 2023, 10:00 AM

#

alright i found the issue

#

String[] values = line.split(",");
tablo teblo = new tablo(line, line, 0, 0);

#

you never use values

#

you just put the line into the table twice

#

you need to do value[0], value[1] etc

mental elbow Jan 12, 2023, 10:03 AM

#

    tablo teblo=new tablo(values[1],values[2],values[3],values[4]);```

#

doesn't work

mental elbow Jan 12, 2023, 10:04 AM

#

slender hinge alright i found the issue

by the way thank you for taking the time for me up_vote

slender hinge Jan 12, 2023, 10:04 AM

#

because for the 2 integers, you need to use Integer.parseInt(whatever)

#

and array indexs start at 0, not 1

mental elbow Jan 12, 2023, 10:08 AM

#

like ```
tablo teblo=new tablo(values[1],values[2], Integer.parseInt(values[3]), Integer.parseInt(values[4]));

#

Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 4 out of bounds for length 4

#

error 😦

slender hinge Jan 12, 2023, 10:10 AM

#

again

#

array indexing starts at zero, not one

#

so you would start the first value using values[0] not values[1]

mental elbow Jan 12, 2023, 10:11 AM

#

ohh

#

you are my super hero

#

❤️

#

I am thankful to you

#

I've been fighting this for 3 hours

slender hinge Jan 12, 2023, 10:12 AM
