Example #1:
// Scala program of nonEmpty() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating an Iterator
val iter = Iterator( 3 , 4 , 6 )
// Applying nonEmpty method
val result = iter.nonEmpty
// Displays output
println(result)
}
} |
Output:
true
Example #2:
// Scala program of nonEmpty() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating an empty Iterator
val iter = Iterator()
// Applying nonEmpty method
val result = iter.nonEmpty
// Displays output
println(result)
}
} |
Output:
false
