javafx - Creating rows after creating custom columns -


i creating scoreboard javafx.
program has table, 1 column game id. when press new game can add 10 players. type in players names , press button add players table columns. have provided pics below can have clearer understanding.

adding players

after players added columns

here i'm stuck. need add scores per game on rows. since i'm generating custom number (2-10) of columns depending on number of players. can't use code because don't know how many parameter needed score constructor in score class.

is there way create 3 int parameter in score class if there 3 players added? or approach in different way? option maybe add random numbers below dynamically editing rows real score, again program doesn't know how many columns there hard well.

public observablelist<score> getscore() {         observablelist<score> scores= fxcollections.observablearraylist();         scores.add(new score(10,12,13,11,15,90));         scores.add(new score(100,10,29,29));         return scores;     }

example of i'm think how should look: 

game nr:|bill gates | steve jobs |    1    |    80     |    10      |    2    |    6      |    75      |

ps: there way sum column , show total score. want sum on last row if add new row scores sum appear below row.

codes used add players textfield column:

        tablecolumn<player, string> p1 = new tablecolumn<>(player1.gettext());         tablecolumn<player, string> p2 = new tablecolumn<>(player2.gettext());         tablecolumn<player, string> p3 = new tablecolumn<>(player3.gettext());         table.getcolumns().addall(p1, p2, p3);

you can create game class has game number (fixed) , represents scores map players values:

public class game {     private final int gamenumber ;     private final observablemap<string, integer> scores          = fxcollections.observablehashmap();      public game(int gamenumber) {         this.gamenumber = gamenumber ;     }      public observablemap<string, integer> getscores() {         return scores ;     }      public int getgamenumber() {         return gamenumber ;     } }

if understand requirements correctly, when user enters new players, want reset table, can method below:

private tableview<game> scoretable ;  // ...  private void resettable(list<string> players) {     scoretable.getcolumns().clear();     scoretable.getitems().clear();      tablecolumn<game, integer> gamenumcol = new tablecolumn<>("game");     gamenumcol.setcellvaluefactory(celldata -> new observablevaluebase<integer>() {         @override         public integer getvalue() {             return celldata.getvalue().getgamenumber();         }     });     scoretable.getcolumns().add(gamenumcol);      (string player : players) {         tablecolumn<game, integer> col = new tablecolumn<>(player);         col.setcellvaluefactory(celldata -> {             game game = celldata.getvalue();             integerbinding score = bindings.createintegerbinding(() ->                game.getscores().getordefault(player, 0),                game.getscores());             return score.asobject() ;         });         // if need editing:         col.setoneditcommit(e -> {             game game = e.getrowvalue();             integer newscore = e.getnewvalue();             game.getscores().put(player, newscore);         });         scoretable.getcolumns().add(col);     } }

then can add new games table's items list, , default 0 scores each player. can set scores with

game.getscores().put(player, score);

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
