What is the difference between static, public, and void

Static do net requires any refrence

Public Acessable across the application and assambly 

void returns nothing

Quotes About Hard Work:
 Dreams don’t work unless you do.

Static means the method belongs to the class, not objects.
Public means it is accessible from anywhere.
Void means it returns nothing.

 public : The method or variable is accessible from anywhere, including other classes.

public int Add(int a, int b) { return a + b; }

Here the  method can be called from outside the class because it is marked as public.

static : Belongs to the class itself, not to an instance (object) of the class.

public static void Greet() { Console.WriteLine("Good morning!"); }

Here you can call Greet() without creating an object of the class

Program.Greet();

void: The method does not return any value.

public void ShowMessage() { Console.WriteLine("Sample  message."); }

The method prints something but doesn’t return anything.

Here is the Key difference

1. Public is an access modifier.public means the method is accessible from anywhere, even outside the class or assembly.

   public void Greet()
   {
       Console.WriteLine("Hello!");
   }

2. static is a non instance modifier, means the method belongs to the class not its object. We don't need to create an object of the class to call a static method.

   public static void ShowTime()
   {
       Console.WriteLine(DateTime.Now);
   }

    

3. void is a return type which specifies that method doesn't return any value.

   public void PrintName(string name)
   {
       Console.WriteLine("Name is: " + name);
   }
