//class banakar ham uska obkect bana skte hai 
//aur subclass banakar bhi uska ham object bana skte hai 
//par agr ek class ho aur uski properties extend ki ho 
//to ham super class ka reference lekar subclass ka object bana skte hai 
//aur agr hamne fynction ko call kiya to subclass ka matlab jiska object hai vo hi run hoga 
//lekin subclass ki method run hone ke liye same method super class me bhi honi chahiye
//it is run time polymorphision
