Scala Mutable SortedSet forall() 方法
在 Scala 可变集合中,SortedSet forall()方法用于检查给定谓词是否满足 SortedSet 的所有元素。
Method Definition: def forall(p: (A) => Boolean): Boolean
Return Type: It returns true if the stated predicate holds true for all the elements of the SortedSet else it returns false.
示例 #1:
// Scala program of forall()
// method
import scala.collection.mutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(13, 7, 12, 9, 21)
// Applying forall method
val result = s1.forall(y => {y % 3 == 0})
// Displays output
println(result)
}
}
输出:
false
示例 #2:
// Scala program of forall()
// method
import scala.collection.mutable.SortedSet
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(15, 12, 21, 30)
// Applying forall method
val result = s1.forall(y => {y % 3 == 0})
// Displays output
println(result)
}
}
输出:
true
