Scala 不可变 TreeSet find() 方法

在 Scala 不可变TreeSet class中,使用find()方法返回满足 TreeSet 中给定谓词的元素。

示例 #1:

// Scala program of find() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// 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 find() method  
        val result = t1.find(x => {x % 7 == 0})
          
        // Displays output 
        println("Element divisible by 7: " + result)
          
    } 
} 
输出:
TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 7: Some(7)

示例 #2:

// Scala program of find() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// 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 find() method  
        val result = t1.find(x => {x % 10 == 0})
          
        // Displays output 
        println("Element divisible by 10: " + result)
          
    } 
} 
输出:
TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 10: None
