Scala immutable TreeSet contains() method

In Scala immutable TreeSet class, the contains() method is utilized to check if an element is present in the TreeSet of not.

Method Definition: def contains(elem: A): Boolean Return Type: It returns true if the element is present in the TreeSet or else it returns false.

Example #1:

Scala

// Scala program of contains() 
// method 

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

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSet
        val t1 = TreeSet(41, 12, 23, 43, 1, 72) 
        
        // Print the TreeSet
        println(t1) 
        
        // Applying contains() method  
        val result = t1.contains(10)
        
        // Display output 
        print("TreeSet contains '10': " + result) 
         
    } 
}

Output:

TreeSet(1, 12, 23, 41, 43, 72)
TreeSet contains '10': false

Example #2:

Scala

// Scala program of contains() 
// method 

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

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSet
        val t1 = TreeSet("g", "e", "e", "k", "s") 
        
        // Print the TreeSet
        println(t1) 
        
        // Applying contains() method  
        val result = t1.contains("k")
        
        // Display output 
        print("TreeSet contains 'k': " + result) 
         
    } 
}

Output:

TreeSet(e, g, k, s)
TreeSet contains 'k': true
