Split / ArrayIndexOutOfBoundsException

Canabral — Tue, 02 May 2023 15:18:15 GMT

Hello,

I have a csv file:

COL1|COL2|COL3

avant|99999;88888;77777|après

I want to split column 2.

So I did in a JavaRow:

output_row.COL1 = input_row.COL1;

output_row.COL2_1 = StringHandling.TRIM(input_row.COL2).split(";")[0];

output_row.COL2_2 = StringHandling.TRIM(input_row.COL2).split(";")[1];

output_row.COL2_3 = StringHandling.TRIM(input_row.COL2).split(";")[2];

output_row.COL3 = input_row.COL3;

But I have this error: java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

it's ok only with

output_row.COL2_1 = StringHandling.TRIM(input_row.COL2).split(";")[0];

I don't understand because I have 3 elements and if I test with

StringHandling.TRIM(input_row.COL2).split(";").length,

it turns out 3 for me...

Thanks for your help.

Hello @Simon Thieffry ,

I can't reproduce the issue in my side, could you please provide the whole job execution error log for more investigation? thanks

Best regards

Aiming

Hello,

No, there is no space in my separator, that is semicolon.

But using the code with the intermediate variable it works :

String[] col2Values = StringHandling.TRIM(input_row.COL2).split("; ");

output_row.COL2_1 = col2Values.length >= 1 ? col2Values[0] : "";

output_row.COL2_2 = col2Values.length >= 2 ? col2Values[1] : "";

output_row.COL2_3 = col2Values.length >= 3 ? col2Values[2] : "";

Thanks.
