Method Definition: def take(n: Int): Map[A, B]
Return Type: It returns the first ‘n’ elements of the map.
Example #1:
// Scala program of take() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a map
val m 1 = Map( 3 - > "geeks" , 4 - > "for" , 2 - > "cs" )
// Applying take method
val result = m 1 .take( 2 )
// Displays output
println(result)
}
} |
Output:
Map(3 -> geeks, 4 -> for)
Example #2:
// Scala program of take() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a map
val m 1 = Map( 3 - > "geeks" , 4 - > "for" , 2 - > "cs" )
// Applying take method
val result = m 1 .take( 4 )
// Displays output
println(result)
}
} |
Output:
Map(3 -> geeks, 4 -> for, 2 -> cs)
