How to append a whole array to an array in Scala? [duplicate]

Question

Say, I have an array with values (1, 2, 3) and another one with (4, 5, 6). How can I have a resultant array with values (1, 2, 3, 4, 5, 6)?

I tried to use ++, but that doesn't work. For example, this is what I got in the command shell.

scala> val x = Array((1, 2, 3))
x: Array[(Int, Int, Int)] = Array((1,2,3))

scala> val y = Array((4, 5, 6))
y: Array[(Int, Int, Int)] = Array((4,5,6))

scala> val z = x ++ y
z: Array[(Int, Int, Int)] = Array((1,2,3), (4,5,6))

Whereas I want Array(1, 2, 3, 4, 5, 6).

EDIT

I was actually using array of tuples, my bad. The Array should have been declared as Array(1, 2, 3) and not Array((1, 2, 3)).

Answer 1

val res = Array(1, 2, 3) ++ Array(4, 5, 6)
