Shouldn't "list" be a parameter of the method Create()?

PHP Code:

---

    static LinkedList<People> Create(String nameFile)
        throws IOException
    { LinkedList<People> list = new LinkedList<People>();
      boolean Fileexists = true ;

       FileReader fi = null; 


       try {
             fi = new FileReader (nomFichier) ;
       }

       catch ( java.io.FileNotFoundException erreur) {
            System.out.println("Probleme d'ouvrir le fichier " +
                 nameFile);
            Fileexists = false ;
       }

       if (Fileexists) {


          BufferedReader enter = new BufferedReader(fi);
          boolean endFile = false ;


          while ( !endFile ) {


           String aLine = enter.readLine();


           if (aLine == null)
                endFile = true ;
           else {
          
                String name = aLine.substring(0, 10);
                char   sex   = aLine.charAt(30);
                double height = Double.parseDouble(aLine.substring(37, 41));
                 double weight  = Double.parseDouble(aLine.substring(51, 56).trim());
                 int    number = Integer.parseInt(aLine.substring(64));

                liste.add(new People(name, sex, height, weight, number));
           }
          }
         enter.close();
        }

      return list;
    }

Please explain your question.

Since we return list, shouldn't list be a parameter of the method create()?

I thought we'd have to write: "create(String nameFile, List[] list)" or something similar.

It all depends on what the create method is supposed to do. With a name like: create, I'd assume that it would create the list and return it It would not be a parameter to the method. A method named: update() might take a list as a parameter.

Wait, I think I remember now... You don't need to declare it if it's an array that's returned, only if it's an integer double or a string and so on. Right?

Why do you mean, "don't need to declare".
Clarify please.
