        // Creating TreeSets
        val t1 = TreeSet(2, 1, 3, 1, 4, 5, 6
          
        val t2 = TreeSet(2, 4, 6)
          
        // Print the TreeSets
        println(t1
          
        println(t2)
          
        // Applying &() method  
        val result = t1.&(t2)
          
        // Display output 
        print("TreeSet containing common elements: " + result)
