C#

Quote:

1. Default Implementations: As mentioned earlier, interfaces can now have default implementations of methods. This allows you to add new methods to your interfaces without breaking existing implementations.

2. Static and Instance Members: Interfaces can now contain static methods, instance methods, and operators.

3. Private and Protected Members: Interfaces can now contain private and protected members. This can be useful for providing helper methods used by the default implementations.

static void Main(string[] args)

Person person = new Person();

person.Name = "Daniel";
 person.Age = 28;
 person.Haspet = true;

person.Greeting();

public void Greeting()
        {
            Console.WriteLine("Within Greeting method. Name is:" + Name +" age is:"+ Age);
            Console.ReadLine();
        }

// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");
namespace crltemp
{
    public class Person
    {
        public string Name;
        public int Age;
        public bool Haspet;

        public void Greeting()
        {
            Console.WriteLine("Within Greeting method. Name is:" + Name + " age is:" + Age);
            Console.ReadLine();
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            Person person = new Person();
            person.Name = "Daniel";
            person.Age = 28;
            person.Haspet = true;

            person.Greeting();

        }
