Scala immutable TreeSet diff()用法及代码示例


在Scala不可变的TreeSet类中,使用diff()方法查找两个TreeSet之间的差异。它从另一个TreeSet中删除一个TreeSet中存在的元素。

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

Return Type: It returns a new TreeSet which consists of elements after the difference between the two given TreeSet.

范例1:

// Scala program of diff()  
// method  
  
// Import TreeSet 
import scala.collection.immutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSet 
        val t1 = TreeSet(1, 2, 3, 4, 5)   
            
        val t2 = TreeSet(3, 4, 5)   
            
        // Print the TreeSet  
        println("TreeSet_1:" + t1)  
            
        println("TreeSet_2:" + t2)  
            
        // Applying diff method   
        val result = t1.diff(t2)   
            
        // Displays output   
        print("(TreeSet_1 - TreeSet_2):" + result)  
          
    }  
} 
输出:
TreeSet_1:TreeSet(1, 2, 3, 4, 5)
TreeSet_2:TreeSet(3, 4, 5)
(TreeSet_1 - TreeSet_2):TreeSet(1, 2)

范例2:

// Scala program of diff()  
// method  
  
// Import TreeSet 
import scala.collection.immutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSet 
        val t1 = TreeSet(1, 2, 3, 4, 5)   
            
        val t2 = TreeSet(3, 4, 5, 6, 7, 8)   
            
        // Print the TreeSet  
        println("TreeSet_1:" + t1)  
            
        println("TreeSet_2:" + t2)  
            
        // Applying diff method   
        val result = t2.diff(t1)   
            
        // Displays output   
        print("(TreeSet_2 - TreeSet_1):" + result)  
          
    }  
} 
输出:
TreeSet_1:TreeSet(1, 2, 3, 4, 5)
TreeSet_2:TreeSet(3, 4, 5, 6, 7, 8)
(TreeSet_2 - TreeSet_1):TreeSet(6, 7, 8)
