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

    PHP Code:
        static LinkedList<PeopleCreate(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(010);
                    
    char   sex   aLine.charAt(30);
                    
    double height Double.parseDouble(aLine.substring(3741));
                     
    double weight  Double.parseDouble(aLine.substring(5156).trim());
                     
    int    number Integer.parseInt(aLine.substring(64));

                    
    liste.add(new People(namesexheightweightnumber));
               }
              }
             
    enter.close();
            }

          return list;
        }

    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.
