scala 同时赋值多个变量

  val Array(a, b, c) = Array(1, 2, 3)
  println(a) //1
  println(b) //2
  println(c) //3

  val a,b,c = Array(1,2,3)
  println(a.mkString("Array(", ", ", ")"))//Array(1, 2, 3)
  println(b.mkString("Array(", ", ", ")")) //Array(1, 2, 3)
  println(c.mkString("Array(", ", ", ")")) //Array(1, 2, 3)

  val (a,b,c)=(1,2,4)
  println(a) //1
  println(b) //2
  println(c)  //4
