What is a supertype method?

Question

I have googled couple of times but still can\'t understand the supertype method. Can anyone please explain what is this?

Answer 1

Super Type and sub type is a property of inheritance i.e for the purpose of re-usability of code. I am giving you example of Super Class and Sub class. For more you can follow here.

using System;

namespace MultilevelInheritance
{
    public class Customer
    {
        public float fDis { get; set; }
        public Customer()
        {
            Console.WriteLine("I am a normal customer.");
        }
        public virtual void discount()
        {
            fDis = 0.3F;
            Console.WriteLine("Discount is :{0}", fDis);
        }

    }
    public class SilverCustomer : Customer
    {
        public SilverCustomer()
            : base()
        {
            Console.WriteLine("I am silver customer.");
        }
        public override void discount()
        {
            fDis = 0.4F;
            Console.WriteLine("Discount is :{0}", fDis);
        }
    }
    class GoldenCustomer : SilverCustomer
    {
        public GoldenCustomer()
        {
            Console.WriteLine("I am Golden customer.");
        }
        public override void discount()
        {
            fDis = 0.6F;
            Console.WriteLine("Discount is :{0}", fDis);
        }

    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MultilevelInheritance
{
    class Program
    {
        static void Main(string[] args)
        {
            Customer objCus = new Customer();
            objCus.discount();

            SilverCustomer objSil = new SilverCustomer();
            objSil.discount();

            GoldenCustomer objGold = new GoldenCustomer();
            objGold.discount();


            Console.ReadLine();
        }
    }
}
