Scala TreeSet dropRight()用法及代码示例


在 Scala TreeSet class,则dropRight()方法用于删除TreeSet的最后一个“ n”个元素。

函数定义: def dropRight(n: Int): TreeSet[A]

返回类型: It returns a new TreeSet that consists of all the elements except the last ‘n’ elements.



范例1:

// Scala program of dropRight()  
// method  
  
// Import TreeSet 
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSet 
        val t1 = TreeSet(2, 4, 6, 7, 8, 9)  
          
        // Print the TreeSet 
        println(t1)  
          
        // Applying dropRight() method   
        val result = t1.dropRight(2) 
          
        // Displays output  
        println("Queue after using dropRight(2) method: " + result) 
          
    }  
} 
输出:
TreeSet(2, 4, 6, 7, 8, 9)
Queue after using dropRight(2) method: TreeSet(2, 4, 6, 7)

范例2:

// Scala program of dropRight()  
// method  
  
// Import TreeSet 
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating TreeSet 
        val t1 = TreeSet(2, 4, 6, 7, 8, 9)  
          
        // Print the TreeSet 
        println(t1)  
          
        // Applying dropRight() method   
        val result = t1.dropRight(4) 
          
        // Displays output  
        println("Queue after using dropRight(4) method: " + result) 
          
    }  
} 
输出:
TreeSet(2, 4, 6, 7, 8, 9)
Queue after using dropRight(4) method: TreeSet(2, 4)
