Scala Tuple: Concatenate two tuples

Last update on December 21 2024 10:25:30 (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.
