Is volgens mij ook nog niet zo moeilijk:

public final class Boolean{
  public static Boolean TRUE = new Boolean();
  public static Boolean FALSE = new Boolean();

  private final Boolean(){
  }

  public void not(Boolean B){
   if(B == TRUE) return FALSE;
   return TRUE;
  }
  etc..
}

Nu heeft Boolean maar twee mogelijke instanties namelijk TRUE en FALSE.
Hetzelfde kun je doen voor andere dingen.

Groetjes Ingo
