{
// Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(1, 2, 3, 4, 1)
// Applying takeRight method
val result = s1.takeRight(4)
// Display output
println(result)
}
}
输出:
Set(1, 2, 3, 4)
示例 #2:
// Scala program of takeRight()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(41, 12, 23, 43)
// Applying takeRight method
val result = s1.takeRight(3)
// Display output
println(result)
}
}
