Zip基本語法:

• zipWithInedx

   1: scala> val employeeWithInedx=List("Andy", "Benson", "Mark").zipWithIndex 

   2: employeeWithInedx: List[(String, Int)] = List((Andy,0), (Benson,1), (Mark,2))

• zip(Stream from N)

   1: scala> val employeeWithInedx=List("Andy", "Benson", "Mark").zip(Stream from 2)

   2: employeeWithInedx: List[(String, Int)] = List((Andy,2), (Benson,3), (Mark,4))

 

Scala:

• zip 是將兩個集合做合併，若其中一個集合數量不匹配時，則無法匹配的項目將被省略。

 

   1: val symbols=Array("*","-","O")

   2: val counts=Array(1,2,3)

   3: var   pairs=symbols.zip(counts)

   4: println(pairs)

 

 
 

Result:
