is your Java's "Hello World" OOP enough?

oophelloworld.java

interface Printer { 
  void print(Message message); 
} 

class Message { 
  private String message; 
  
  public Message(String message) { 
   this.message = message; 
  } 
  
  public void print(Printer printer) { 
    printer.print(this); 
  } 
 
  public String toString() { 
   return message; 
  } 
} 

abstract class AbstractPrinterFactory { 
  public static AbstractPrinterFactory getFactory(){ 
   return new SystemOutPrinterFactory(); 
  } 
  
  public abstract Printer getPrinter(); 
} 

class SystemOutPrinterFactory extends AbstractPrinterFactory { 
  public Printer getPrinter() { 
    return new SystemOutPrinter(); 
  } 
} 

class SystemOutPrinter implements Printer { 
  public void print(Message message) { 
   System.out.println(message); 
  } 
} 

public class HelloWorld { 
  public static void main(String[] args) { 
   Message message = new Message("Hello, World!"); 
   AbstractPrinterFactory factory = AbstractPrinterFactory.getFactory(); 
   Printer printer = factory.getPrinter(); message.print(printer); 
  } 
}

Ah, hardcoded string, meh...
