Scala Set map() method with example

The map() method is utilized to build a new set by applying a function to all elements of this set.

Method Definition: def map[B](f: (A) => B): immutable.Set[B]

Return Type: It returns a new set containing all the elements after applying the given function.

Example #1:

// Scala program of map()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a set
        val s1 = Set(5, 1, 3, 2, 4)

        // Applying map method
        val result = s1.map(x => x*x)

        // Display output
        println(result)
    }
}

Output:

Set(25, 1, 9, 16, 4)

Example #2:

// Scala program of map()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a set
        val s1 = Set(5, 1, 3, 2, 4)

        // Applying map method
        val result = s1.map(x => x/2)

        // Display output
        println(result)
    }
}

Output:

Set(2, 0, 1)
