Kotlin 範圍

示例

列印整個字母表

for (chars in 'a'..'x') {
  println(chars)
}

示例

for (nums in 5..15) {
  println(nums)
} 

示例

val nums = arrayOf(2, 4, 6, 8)
if (2 in nums) {
  println("It exists!")
} else {
  println("It does not exist.")
}

示例

val cars = arrayOf("Volvo", "BMW", "Ford", "Mazda")
if ("Volvo" in cars) {
  println("It exists!")
} else {
  println("It does not exist.")
} 

示例

當 nums 等於 10 時停止迴圈

for (nums in 5..15) {
  if (nums == 10) {
    break
  }
  println(nums)
} 

示例

在迴圈中跳過值 10，並繼續下一次迭代

for (nums in 5..15) {
  if (nums == 10) {
    continue
  }
  println(nums)
}
