Scala Tuple: Concatenate two tuples

Last update on June 12 2025 13:01:18 (UTC/GMT +8 hours)

Write a Scala program to concatenate two tuples: (200, "Scala") and (300, "Exercises") should become ("Scala Exercises", 500).

Sample Solution:

Scala Code:

object ConcatenateTuplesExample {
  def main(args: Array[String]): Unit = {
    // Create two tuples
    val tuple1 = (200, "Scala")
    val tuple2 = (300, "Exercises")
    println("Tuple1: "+tuple1)
    println("Tuple2: "+tuple2)
    // Concatenate the tuples
    val concatenatedTuple = (tuple1._1 + tuple2._1, tuple1._2 + " " + tuple2._2)

    // Print the concatenated tuple
    println("Concatenated tuple: " + concatenatedTuple)
  }
}

Sample Output:

Tuple1: (200,Scala)
Tuple2: (300,Exercises)
Concatenated tuple: (500,Scala Exercises)

Explanation:

In the above exercise -

We have two tuples: tuple1 with elements (200, "Scala") and tuple2 with elements (300, "Exercises").
To concatenate the tuples, we create a new tuple concatenatedTuple where the first element is the concatenation of the second elements of tuple1 and tuple2. The second element is the sum of both tuples.
We access the elements of the tuples using the 1 and 2 notation, where 1 represents the first element and 2 represents the second element.
Finally, we print the concatenated tuple using println.

Go to:

PREV : Swap tuple elements.
NEXT : Check if a specific element exists in a tuple.
