Scala immutable TreeSet &~()用法及代码示例

在 Scala 中不可变TreeSet class，这&~()方法用于返回一个新的TreeSet，其中包含两个 TreeSet 之间的差异。

函数定义： def &~(that: TreeSet[A]): TreeSet[A]

返回类型： It returns a new TreeSet which contains the difference between two TreeSets.

示例#1：


// Scala program of &~()  
// method  
  
// Import TreeSet 
import scala.collection.immutable._
  
// 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.immutable._
  
// 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)
