Scala immutable TreeSet dropWhile() method

In Scala immutable TreeSet class, the dropWhile() method is utilized to drop the longest prefix from the front which satisfies a given predicate in a TreeSet.

Method Definition: def dropWhile(p: (A) => Boolean): TreeSet[A] Return Type: It returns a new TreeSet that consists of elements after dropping the longest prefix satisfying the given predicate.

Example #1:

Scala

// Scala program of dropWhile() 
// 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 dropWhile() method  
        val result = t1.dropWhile(x => {x % 2 == 0})
        
        // Displays output 
        println("TreeSet after using dropWhile() method: " + result)
        
    } 
}

Output:

TreeSet(2, 4, 6, 7, 8, 9)
TreeSet after using dropWhile() method: TreeSet(7, 8, 9)

Example #2:

Scala

// Scala program of dropWhile() 
// method 

// Import TreeSet
import scala.collection.immutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSet
        val t1 = TreeSet(3, 5, 6, 7, 8, 9) 
        
        // Print the TreeSet
        println(t1) 
        
        // Applying dropWhile() method  
        val result = t1.dropWhile(x => {x % 2 != 0})
        
        // Displays output 
        println("TreeSet after using dropWhile() method: " + result)
        
    } 
}

Output:

TreeSet(3, 5, 6, 7, 8, 9)
TreeSet after using dropWhile() method: TreeSet(6, 7, 8, 9)
