&~()方法用于创建一个由两个给定集合之间的差异之后的元素组成的新集合。
Method Definition: def &~(that: Set[A]): Set[A]
Return Type: It returns a set consisting of elements after the difference between two given sets.
示例 #1:
// Scala program of &~()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(41, 12, 23, 43, 1, 72)
val s2 = Set(1, 100, 5, 12, 23)
// Applying &~() method
val result = s1.&~(s2)
// Display output
print(result)
}
}
输出:
Set(41, 72, 43)
示例 #2:
// Scala program of &~()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(1, 2, 5, 3, 4)
val s2 = Set(2, 4)
// Applying &~() method
val result = s2.&~(s1)
// Display output
print(result)
}
}
输出:
Set()
