Scala Tuple: Create a tuple from two lists

Last update on December 21 2024 10:28:04 (UTC/GMT +8 hours)

Write a Scala program that creates a tuple from two lists.

Sample Solution:

Scala Code:

object TupleFromListsExample {
  def main(args: Array[String]): Unit = {
    // Create two lists
    val list1 = List("Red", "Green", "Blue")
    val list2 = List(1, 3, 5)
    // Print said two lists
    println("List1: " + list1)
    println("List2: " + list2)
    // Create a tuple from the lists
    val new_tuple = list1.zip(list2)
    // Print the tuple
    println("Tuple from said two lists: " + new_tuple)
  }
}

Sample Output:

List1: List(Red, Green, Blue)
List2: List(1, 3, 5)
Tuple from said two lists: List((Red,1), (Green,3), (Blue,5))

Explanation:

In the above exercise -

• First, we create two lists: list1 with elements "Red", "Green", and "Blue", and list2 with elements 1, 3, and 5.
• To create a tuple from these lists, we use the zip method, which combines the elements of the two lists pairwise. It returns a new collection of tuples, where each tuple contains an element from list1 and its corresponding element from list2.
• We assign the resulting tuple to the variable tuple.
• Finally, we print the tuple using println.
