Decorator

This is the class that will be "decorated".
The functionality of one of these objects (not the
class itself) will be extended through the use of a
decorator object.
-----------------------------------------------------
class Person{

    public void makeStatement(String statement){
        System.out.println(statement);
    }
}
-----------------------------------------------------


The decorator class.
NOTE: I believe that the decorator should
not take a person as a constructor arg but have a 
setPerson function. This would enable one decorator
object to "decorate" or extend multiple person objects.
-----------------------------------------------------
class RelativistDecorator{
    private Person person;

    public  RelativistDecorator(Person person){
        this.person = person;
    }

    public void makeStatement(String statement){
        person.makeStatement("In my opinion " 
                                    + statement);
    }
}
-----------------------------------------------------


A test stub to demonstrate the decorator in use.
-----------------------------------------------------
class Test{

    public static void main(String[] args){
        System.out.println("class: Test, method: main");

        String statement = "time alone is good";

        Person person = new Person();
        person.makeStatement(statement);
        new RelativistDecorator(person).makeStatement(statement);
    }
}
-----------------------------------------------------
