如何在scala中迭代数组元素

val array = Array(1, 2, 3, 4, 5)
for (element <- array) {
  println(element)
}

val array = Array(1, 2, 3, 4, 5)
array.foreach(element => println(element))

val array = Array(1, 2, 3, 4, 5)
for (i <- 0 until array.length) {
  println(array(i))
}

val array = Array(1, 2, 3, 4, 5)
var i = 0
while (i < array.length) {
  println(array(i))
  i += 1
}
