您可以添加任意数量的 println() 函数。请注意,它将为每个函数添加一个新行

  println("Hello World!")
  println("I am learning Kotlin.")
  println("It is awesome!")
}

您还可以打印数字,并执行数学运算

print() 函数

还有一个 print() 函数,它类似于 println()。唯一的区别在于它不会在输出末尾插入新行

示例

fun main() {
  print("Hello World! ")
  print("I am learning Kotlin. ")
  print("It is awesome!")
}
自己尝试一下 »

请注意,我们添加了一个空格字符来在句子之间创建空格。
