Scala List.filter with two conditions, applied only once

Question

Don\'t know if this is possible, but I have some code like this:

val list = List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
val evens = list.filter { e => e % 2 =         


        

Answer 1

You just write two conditions in the filter:

val list = List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

var result = List(0)
val someCondition = true

result = if (someCondition) list.filter { e => e % 2 == 0 && e % 3 == 0 }
         else               list.filter { e => e % 2 == 0 && e % 5 == 0 }
