This topic is about Scala Collections – Zip Method.
zip() method is a member of IterableLike trait, it is used to merge a collection to current collection and result is a collection of pair of tuple elements from both collections.
Syntax
The following is the syntax of zip method.
def zip[B](that: GenIterable[B]): Iterable[(A, B)]
Here, zip method takes a collection as parameter. This method returns the updated collection of pair as result.
Usage
Below is an example program of showing how to use zip method −
Example
object Demo {
def main(args: Array[String]) = {
val list = List(1, 2, 3 ,4)
val list1 = List("A", "B", "C", "D")
//apply operation to create a zip of list
val list2 = list zip list1
//print list
println(list2)
}
}
Save the above program in Demo.scala. The following commands are used to compile and execute this program.
Command
\>scalac Demo.scala \>scala Demo
Output
List((1,A), (2,B), (3,C), (4,D))
