Tuple拉链操作
Tuple拉链操作指的就是zip操作
zip操作，是Array类的方法，用于将两个Array，合并为一个Array
比如Array(v1)和Array(v2)，使用zip操作合并后的格式为Array((v1,v2))
合并后的Array的元素类型为Tuple
val students = Array("Leo", "Jack", "Jen")
val scores = Array(80, 100, 90)
val studentScores = students.zip(scores)
for ((student, score) <- studentScores)
println(student + " " + score)
如果Array的元素类型是个Tuple，调用Array的toMap方法，可以将Array转换为Map
studentScores.toMap
Java Map与Scala Map的隐式转换
Java Map转Scala Map
import scala.collection.JavaConversions.mapAsScalaMap
val javaScores = new java.util.HashMap[String, Int]()
javaScores.put("Alice", 10)
javaScores.put("Bob", 3)
javaScores.put("Cindy", 8)
val scalaScores: scala.collection.mutable.Map[String, Int] = javaScores
Scala Map转Java Map
import scala.collection.JavaConversions.mapAsJavaMap
import java.awt.font.TextAttribute._
val scalaAttrMap = Map(FAMILY -> "Serif", SIZE -> 12)
val font = new java.awt.Font(scalaAttrMap)
