Traditional "Hello World" Programme Using Different Approaches. PART-II.

Hello World :)

In Part - I, I tried to explain the very basic "HELLO WORLD" program. In this article, I would use different methods to display "HELLO WORLD" so as to clear some of the OOPS fundamentals. So, without wasting much time, let's go on with it.

EXAMPLE: 1

/* In this Programme you must have noticed
 that there is no base class declaration 
 here but to call WriteLine Method, Base class
  i.e System is appended before Console.*/ 


public class nemesh
{ 
    public static void Main()
     {
       System.Console.WriteLine("HELLO WORLD");
     }
}

EXAMPLE: 2

using system;
public class nemeshc      /* class declared as 'nemeshc' */
{ 
   public void nemeshm()     /* 'method declared as 'nemeshm' */
     {
       Console.WriteLine("HELLO WORLD");
     }

    public static void Main()     /* Main Entry Point */
    {
   /* Object of class 'nemeshc' is constructed */
      nemeshc nem = new nemeshc();
   /* method 'nemeshm' of class 'nemeshc' is called*/
      nem.nemeshm();
    }
}

EXAMPLE: 3

using system;
public class nemeshc      /* class declared as 'nemeshc' */
{
  /* 'nemeshc' constructor is created and it fires when
     the object of the class 'nemeshc' is constructed */ 
   public nemeshc()     
     {
       Console.WriteLine("HELLO WORLD");
     }

    public static void Main()     /* Main Entry Point */
    {
   /* Object of class 'nemeshc' is constructed */
      nemeshc nem = new nemeshc();
    }
}

EXAMPLE: 4

using system;
public class nemeshc      /* class declared as 'nemeshc' */
{ 
    public static void Main()     /* Main Entry Point */
    {
   /* Object of class 'nemesh1c' is constructed */
      nemesh1c nem = new nemesh1c();
   /* Method "neme1" of class 'nemesh1c' is called*/
      nem.neme1();
    }
} 

public class nemesh1c      /* class declared as 'nemesh1c' */
{ 
    public void neme1()     /* Method declared as 'neme1' */
    {
      Console.WriteLine("Hello World");     
    }
}

So folks! How was it? Did you get the things or all went above your head? If you are not able to understand any thing, then please mail me or just create a new thread and leave a message. I would try to explain it more deeply.

In my next article, I would explain to you "The beauty of .NET platform using C# and VB.NET".
