Scala Converting Each Array Element to String and Splitting -

i have array loaded in, , been playing around in repl can't seem work.

my array looks this:

record_id|string|false|1| offer_id|decimal|false|1|1,1 decision_id|decimal|false|1|1,1 offer_type_cd|integer|false|1|1,1 promo_id|decimal|false|1|1,1 pymt_method_type_cd|decimal|false|1|1,1 cs_result_id|decimal|false|1|1,1 cs_result_usage_type_cd|decimal|false|1|1,1 rate_index_type_cd|decimal|false|1|1,1 sub_product_id|decimal|false|1|1,1 campaign_id|decimal|false|1|1,1 

when run command:

for(i <- 0 until schema.length){       val convert = schema(i).tostring;      convert.split('|').drop(2);      println(convert); } 

it won't drop anything. not splitting on |

strings immutable, , split , drop don't mutate string - return new one.

you need capture result in new val

val split = convert.split('|').drop(2);  println(split.mkstring(" "));
