Scala immutable TreeSet intersect()用法及代码示例

在Scala中一成不变TreeSet class，则intersect()方法用于返回新的TreeSet，该树集由两个给定TreeSet中都存在的元素组成。

Method Definition: def intersect[B >:A](that:collection.Seq[B]):TreeSet[A]

Return Type: It returns a new TreeSet that consists of elements that are present in both the given TreeSet.

范例1：

// Scala program of intersect()  
// method  
  
// Import TreeSet 
import scala.collection.immutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSets 
        val t1 = TreeSet(1, 3, 2, 7, 6, 5)  
          
        val t2 = TreeSet(11, 3, 12, 7, 16, 5)  
          
        // Print the TreeSets 
        println("t1:" + t1) 
          
        println("t2:" + t2) 
          
        // Applying intersect() method   
        val result = t1.intersect(t2) 
          
        // Displays output  
        println("TreeSet with common elements:" + result) 
          
    }  
}

输出：

t1:TreeSet(1, 2, 3, 5, 6, 7)
t2:TreeSet(3, 5, 7, 11, 12, 16)
TreeSet with common elements:TreeSet(3, 5, 7)

范例2：

// Scala program of intersect()  
// method  
  
// Import TreeSet 
import scala.collection.immutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSets 
        val t1 = TreeSet(1, 3, 2, 7, 6, 5)  
          
        val t2 = TreeSet(1, 13, 2, 17, 16, 5)  
          
        // Print the TreeSets 
        println("t1:" + t1) 
          
        println("t2:" + t2) 
          
        // Applying intersect() method   
        val result = t1.intersect(t2) 
          
        // Displays output  
        println("TreeSet with common elements:" + result) 
          
    }  
}

输出：

t1:TreeSet(1, 2, 3, 5, 6, 7)
t2:TreeSet(1, 2, 5, 13, 16, 17)
TreeSet with common elements:TreeSet(1, 2, 5)
