带有示例的 Scala TreeSet tail() 方法

tail()方法用于返回一个新的 TreeSet，它由除第一个元素之外的所有元素组成。

Method Definition: def tail: TreeSet[A]

Return Type: It returns a new TreeSet that consists of all the elements except the first one.

示例 #1：

// Scala program of tail() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet(1, 3, 2, 7, 6, 5) 
          
        // Print the TreeSet
        println(t1)
         
        // Applying tail() method  
        val result = t1.tail
          
        // Displays output 
        println("Elements of the TreeSet except the first one: " + result)
          
    } 
} 

输出：

TreeSet(1, 2, 3, 5, 6, 7)
Elements of the TreeSet except the first one: TreeSet(2, 3, 5, 6, 7)

示例 #2：

// Scala program of tail() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet("a", "e", "i", "o", "u") 
          
        // Print the TreeSet
        println(t1)
         
        // Applying tail() method  
        val result = t1.tail
          
        // Displays output 
        println("Elements of the TreeSet except the first one: " + result)
          
    } 
} 

输出：

TreeSet(a, e, i, o, u)
Elements of the TreeSet except the first one: TreeSet(e, i, o, u)
