Scala类型转换

值类型隐式转换

自动类型转换说明

object TypeDemo8 {

  def main(args: Array[String]): Unit = {

    var n1 = 10
    var n2 = 1.1f  // float

    var n3 = n1 + n2
    println(n3.isinstanceOf[Float])
  }
}

object TypeDemo9 {

  def main(args: Array[String]): Unit = {
    var n4:Byte = 10
    var char1:Char = n4  // byte short 和 char 之间不能转换
  }
}

强制类型转换

强制类型转换说明

object TypeDemo10 {


  def main(args: Array[String]): Unit = {

    var num:Int = 2.7f.toInt
    println(num.isinstanceOf[Int])
  }
}

object TypeDemo11 {
  def main(args: Array[String]): Unit = {
    var num1:Int = 10*3.5.toInt + (6 *1.5).toInt
    var num2:Int = (10 * 3.5 + 6 * 1.5).toInt
    println(num1 + num2)
  }
}

object TypeDemo12 {

  def main(args: Array[String]): Unit = {
    var char1:Char = 98
    var num3 = 1

    var char2:Char = num3
  }
}
