OO Hello World - Oxygene

Tweet

The Hello World version of the program in Oxygene is here.

By the way, you can see my previous post here: http://carlosqt.blogspot.com/2010/06/oo-hello-world.html
where I give some details on WHY these "OO Hello World series" samples.

Version 1 (Minimal):

The minimum you need to type to get your program compiled and running.

namespace;

interface
uses  
 System; 

type Greet = class
 private
  var name : string;
 public
  constructor(name : string);
  method Salute;
 end;

type
 GreetProgram = class    
  class method Main(args: array of string);
 end;

implementation

constructor Greet(name : string);
begin
 self.name := name[0].ToString().ToUpper() + name.Substring(1, name.Length - 1);
end;

method Greet.Salute;
begin
 Console.WriteLine("Hello " + name + "!");
end;

class method GreetProgram.Main(args: array of string);
var
 g : Greet;
begin
 g := new Greet("world");    
 g.Salute();
end;
end.

Version 2 (Verbose):

Explicitly adding instructions and keywords that are optional to the compiler.

namespace GreetProgram;

interface
uses  
 System; 

type Greet = public class
 private
  var name : string;
 public
  constructor(name : string);
  method Salute;
 end;

type
 GreetProgram = public class    
    public
  class method Main(args: array of string);
 end;

implementation

constructor Greet(name : string);
begin
 self.name := name[0].ToString().ToUpper() + name.Substring(1, name.Length - 1);
end;

method Greet.Salute;
begin
 Console.WriteLine("Hello " + self.name + "!");
end;

class method GreetProgram.Main(args: array of string);
var
 g : Greet;
begin
 g := new Greet("world");    
 g.Salute();
end;
end.
