You can use
:+ to append element to array and
+: to prepend it:
0 +: array :+ 4
res3: Array[Int] = Array(0, 1, 2, 3, 4)
It's the same as with any other implementation of
The easiest might be:
Array(1, 2, 3) :+ 4
Actually, Array can be implcitly transformed in a
val array2 = array :+ 4 //Array(1, 2, 3, 4)
Works also "reversed":
val array2 = 4 +: array Array(4, 1, 2, 3)
There is also an "in-place" version:
var array = Array( 1, 2, 3 ) array +:= 4 //Array(4, 1, 2, 3) array :+= 0 //Array(4, 1, 2, 3, 0)
