Scala Mutable SortedSet foreach() 方法
在 Scala 可变集合中,SortedSet foreach()方法用于将给定函数应用于 SortedSet 的所有元素。
Method Definition: def foreach(f: (A) => Unit): Unit
Return Type: It returns all the elements of the SortedSet after applying the given function to each of them.
示例 #1:
// Scala program of foreach()
// method
import scala.collection.mutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(13, 22, 19, 21)
// Applying foreach method
s1.foreach(x => println(x))
}
}
输出:
13
19
21
22
示例 #2:
// Scala program of foreach()
// method
import scala.collection.mutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(5, 7, 8, 3, 2)
// Applying foreach method
s1.foreach(x => println(x + " times " + x + " = " + x*x))
}
}
输出:
2 times 2 = 4
3 times 3 = 9
5 times 5 = 25
7 times 7 = 49
8 times 8 = 64
