Difference Between Traits and Abstract Classes in Scala

// Scala program to illustrate how to 
// create an abstract class

// Abstract class
abstract class Abstclass
{
    
    // Abstract and non-abstract method
    def portal
    def tutorial()
    { 
        println("Scala tutorial")
    }

}

// GFG class extends abstract class
class GFG extends Abstclass
{
    def portal()
    {
        println("Welcome!! GeeksforGeeks")
    }
}

object Main 
{
    
    // Main method
    def main(args: Array[String]) 
    {
        // object of GFG class
        var obj = new GFG ();
        obj.tutorial()
        obj.portal()
    }
}

// Scala program to illustrate how to 
// create traits

// traits
trait mytrait
{
    
    // Abstract and non-abstract method
    def portal
    def tutorial()
    { 
        println("Scala tutorial")
    }

}

// GFG class extends trait
class GFG extends mytrait
{
    def portal()
    {
        println("Welcome!! GeeksforGeeks")
    }
}

object Main
