    def main(args:Array[String])
    {
    
        // Creating a Iterator 
        val iter = Iterator(5, 6, 8, 9)
        
        // Applying toSet method 
        val result = iter.toSet

    {
    
        // Creating an empty Iterator 
        val iter = Iterator()
        
        // Applying toSet method 
        val result = iter.toSet
