{ // Main method
def main(args : Array[String])
{
// Creating a set
val s 1 = Set( 1 , 2 , 3 , 4 , 5 )
// Applying isEmpty method
val result = s 1 .isEmpty
// Display output
println(result)
}
} |
Output:
false
Example #2:
// Scala program of isEmpty() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a set
val s 1 = Set()
// Applying isEmpty method
val result = s 1 .isEmpty
// Display output
println(result)
