JAVA FX ObservableList无法初始化

Question

i am creating a TableView in JAVA FX and i have a class Phone to represent my data like the documentation said . the phone class has a SimpleStringProperty phoneName. in the documentation they make the class phone static and the property final. if i make the class static i have an error modifier static not allowed here if i make the property final i can't create setters but in the doc they do

and in my application when a create an ObservableList of phones , when i put data in it like below :

 private ObservableList<Phone> phoneList = FXCollections.observableArrayList(          
        new Phone( "iphone" , "ios")  ,
        new Phone("nexus" , "android") 
          );

i have an error saying : cannot convert String to SimpleStringProperty

Thx u . not that if i remove the static and final keywords and change the properties to normal String , it works but i'am having problems after when i want to make the table editable like i explain here related question

Thx u guys

Answer 1

The Song constructor need to look like this :

public Song(String model,String os){

this.model = new SimpleStringProperty(model);
this.os = new SimpleStringProperty(os);

}

You need to create the SimpleStringProperty with your string.
