Example #1:
// Scala program of size() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a map
val m 1 = Map( 3 - > "geeks" , 1 - > "for" , 2 - > "cs" )
// Applying size method
val result = m 1 .size
// Displays output
println(result)
}
} |
Output:
3
Example #2:
