Scala 不可变 TreeSet sum() 方法

在 Scala 不可变 TreeSet 类中, sum()方法用于返回 TreeSet 的所有元素的总和。

示例 #1:

// Scala program of sum() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 2, 4)  
            
        // Print the TreeSet 
        println(t1) 
          
        // Applying sum method  
        val result = t1.sum
            
        // Displays output  
        print("Sum of all the elements of the TreeSet: " + result) 
          
    } 
} 
输出:
TreeSet(1, 2, 3, 4, 5)
Sum of all the elements of the TreeSet: 15

示例 #2:

// Scala program of sum() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
{ 
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 7, 9)  
            
        // Print the TreeSet 
        println(t1) 
          
        // Applying sum method  
        val result = t1.sum
            
        // Displays output  
        print("Sum of all the elements of the TreeSet: " + result) 
          
    } 
} 
输出:
TreeSet(1, 3, 5, 7, 9)
Sum of all the elements of the TreeSet: 25
