// Scala program of equals() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSets
        val t1 = TreeSet(1, 3, 2, 7, 6, 5
          
        val t2 = TreeSet(1, 3, 2, 7, 6, 5
          
        // Print the TreeSets
        println("t1: " + t1)
          
        println("t2: " + t2)
          
        // Applying equals() method  
        val result = t1.equals(t2)
          
        // Displays output 
        println("Both the TreeSets are equal: " + result)

Output:

t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(1, 2, 3, 5, 6, 7)
