Scala Set ++() 方法与示例
++() 方法用于将一个集合的元素添加到另一个集合。
Method Definition: def ++(elems: A): Set[A]
Return Type: It returns a new set containing elements of both the 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(1, 3, 5)
val s2 = Set(2, 4, 6)
// Applying ++() method
val result = s1 ++ s2
// Display output
print(result)
}
}
输出:
Set(5, 1, 6, 2, 3, 4)
示例 #2:
// 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(5, 1, 41, 12, 72, 43, 23, 100)
