Replace Conditional Statements (IF/ELSE or SWITCH) With Polymorphism

Handler.cs

class Handler
{
     public void increaseSpeed(GameObject go1)
     {
          if(typeOf(go1) == Rabbit )
          {
            // increase speed by 3
          }
           else if(typeOf(go1) == Bear)
          {
             // increase speed by 2
          }
           else if(typeOf(go1) == Turtle)
          {
            // increase speed by 1
          }
     }
}
