带有示例的 Scala ListSet takeWhile() 方法
在 Scala ListSet 中,只要满足规定的条件,就会使用takeWhile()
方法从列表中查找元素。
Method Definition: def takeWhile(p: (A) => Boolean): ListSet[A]
Return Type: It returns the elements from the list as long as the stated condition is satisfied.
示例 1:
// Scala program of takeWhile()
// method
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a list
val m1 = ListSet(1, 2, 3, 4, 5, 7)
// Applying takeWhile method
val result = m1.takeWhile(_ > 3)
// Displays output
println(result)
}
}
输出:
ListSet(4, 5, 7)
示例 2:
// Scala program of takeWhile()
// method
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a list
val m1 = ListSet(1, 2, 3, 4, 5, 7)
// Applying takeWhile method
val result = m1.takeWhile(_ > 7)
// Displays output
println(result)
}
}
输出:
ListSet()
