Scala TreeSet ++()用法及代碼示例


在 Scala 中TreeSet class, 這++()方法用於將一個 TreeSet 的元素添加到另一個 TreeSet。

函數定義: def ++(that: IterableOnce[A]): TreeSet[A]

返回類型: It returns a new TreeSet which contains all the element from both the given 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("g", "e", "e", "k", "s")  
          
        val t2 = TreeSet("a", "e", "i", "o", "u") 
          
        // Print the TreeSets 
        println(t1)  
          
        println(t2) 
          
        // Applying ++() method   
        val result = t1 ++ t2
          
        // Display output  
        print("Combined TreeSet: " + result)  
           
    }  
}  
輸出:
TreeSet(e, g, k, s)
TreeSet(a, e, i, o, u)
Combined TreeSet: TreeSet(a, e, g, i, k, o, s, u)

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(1, 6, 3, 2, 5)  
          
        val t2 = TreeSet(2, 1, 5, 4, 1) 
          
        // Print the TreeSets 
        println(t1)  
          
        println(t2) 
          
        // Applying ++() method   
        val result = t1 ++ t2
          
        // Display output  
        print("Combined TreeSet: " + result)  
           
    }  
}  
輸出:
TreeSet(1, 2, 3, 5, 6)
TreeSet(1, 2, 4, 5)
Combined TreeSet: TreeSet(1, 2, 3, 4, 5, 6)
