Given
scala> val a = (1 to 9).toArray
a: Array[Int] = Array(1, 2, 3, 4, 5, 6, 7, 8, 9)
would like to group elements in a
in this way,
Array(Array(1,2,3), Array(4,5,6), Array(7,8,9))
If you want to get groups by 3 elements you could use method grouped
:
a.grouped(3).toArray
// Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))
