Scala TreeSet &~() 方法示例
在 Scala TreeSet class中， &~()方法用于返回一个新的 TreeSet，其中包含两个 TreeSet 之间的差异。
Method Definition: def &~(that: TreeSet[A]): TreeSet[A]
Return Type: It returns a new TreeSet which contains the difference between two TreeSets.
示例 #1：
// Scala program of &~()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(2, 1, 3, 1, 4, 5, 6)
val t2 = TreeSet(2, 4, 6)
// Print the TreeSets
println(t1)
println(t2)
// Applying &~() method
val result = t1.&~(t2)
// Display output
print("TreeSet containing difference of two TreeSets: " + result)
}
}
输出：
TreeSet(1, 2, 3, 4, 5, 6)
TreeSet(2, 4, 6)
TreeSet containing difference of two TreeSets: TreeSet(1, 3, 5)
示例 #2：
// Scala program of &~()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet("g", "e", "e", "k", "s", "f", "o", "r")
val t2 = TreeSet("g", "e", "e", "k", "s")
// Print the TreeSets
println(t1)
println(t2)
// Applying &~() method
val result = t1.&~(t2)
// Display output
print("TreeSet containing difference of two TreeSets: " + result)
}
}
输出：
TreeSet(e, f, g, k, o, r, s)
TreeSet(e, g, k, s)
TreeSet containing difference of two TreeSets: TreeSet(f, o, r)
