sauvegarder les donnees d'un tableauRésolu

Question

Bonjour, 
SVP j'ai besoin d'un code qui me permet de sauvegarder les donnees de mon tableau dinamique dans un fichier texte et de les récuperées au prochain lancement du programme. je vous en serais reconnaissant pour votre aide

Bonjour,

Regarde les méthodes Path Files.write(Path, Iterable<String>)
et List<String> Files.readAllLines(Path) du package java.nio.file.*

Exemple :

Path path = Paths.get("C:/test.txt");
Files.write(path, Arrays.asList("a", "b"));
System.out.println(Files.readAllLines(path)); // [a, b]

La confiance n'exclut pas le contrôle

Slt KX,
merci pour tes reponses;
au faite je ne maitrise vraiment pas la chose, voilà ma classe fenetre:
  public class Fenetre extends JFrame  {	 	private Model modele = new Model();    private JTable tableau;            public Fenetre() {        super();        this.setTitle("CORE");        this.setSize(1500, 600);      this.setLocationRelativeTo(null);           this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        tableau = new JTable(modele);        tableau.setAutoCreateRowSorter(true);                               getContentPane().add(new JScrollPane(tableau), BorderLayout.CENTER);        JPanel boutons = new JPanel();        boutons.add(new JButton(new AddAction()));        boutons.add(new JButton(new RemoveAction()));        getContentPane().add(boutons, BorderLayout.SOUTH);                     }    public static void main(String[] args) {   	 Fenetre fen = new Fenetre();   	fen.setVisible(true);      }    private class AddAction extends AbstractAction {        private AddAction() {            super("Ajouter");        }        public void actionPerformed(ActionEvent e) {        	             modele.addSource(new Source("", "", "", "","","","","",""));        }    }    private class RemoveAction extends AbstractAction {        private RemoveAction() {            super("Supprimmer");        }        public void actionPerformed(ActionEvent e) {            int[] selection = tableau.getSelectedRows();                        for(int i = selection.length - 1; i >= 0; i--){            	JOptionPane jop3 ;            jop3 = new JOptionPane();            jop3.showMessageDialog(null, "VOUS NE POUREZ PLUS RECUPERE CES INFORMATIONS APRES SUPPRESSION", "ATTENTION", JOptionPane.ERROR_MESSAGE);            	                modele.removeSource(selection[i]);            }        }    }     } 
merci de bien vouloir m'aider

voici ma classe modele:


public class Model extends AbstractTableModel {
    private final List<Source> sources = new ArrayList<Source>();

    private final String[] entetes = {"SIT ","NO  ","DATE", "HEURE  ", "DATE ", "HEURE ", "DATE ","HEURE  ", "TEMPS  "};

    public Model() {
        super();

        sources.add(new Source("", "", "", "", "","","","",""));
        sources.add(new Source("", "", "","", "","","","",""));
        sources.add(new Source("", "", "","", "","","","",""));
       
    }

    public int getRowCount() {
        return sources.size();
    }

    public int getColumnCount() {
        return entetes.length;
    }

    public String getColumnName(int columnIndex) {
        return entetes[columnIndex];
    }

    public Object getValueAt(int rowIndex, int columnIndex) {
        switch(columnIndex){
            case 0:
                return sources.get(rowIndex).getKom();
            case 1:
                return sources.get(rowIndex).getNir();
            case 2:
                return sources.get(rowIndex).getCot();
            case 3:
                return sources.get(rowIndex).setHor();
            case 4:
                return sources.get(rowIndex).getSp();
            case 5 :
             return sources.get(rowIndex).getHh();
            case 6:
             return sources.get(rowIndex).getDh();
            case 7:
             return sources.get(rowIndex).getDd();
            case 8:
             return sources.get(rowIndex).getTt();
            default:
                return null;  
        }
    }

    @Override
    public Class getColumnClass(int columnIndex){
        switch(columnIndex){
        case 0:
         return String.class;
        case 1:
         return String.class;
            case 2:
                return String.class;
            case 3:
                return String.class;
            case 4 :
                return String.class;
            case 5:
             return String.class;
            case 6:
            return String.class;
            case 7:
             return String.class;
            default:
                return Object.class;
        }
    }

    @Override
    public boolean isCellEditable(int rowIndex, int columnIndex) {
        return true;  
    }

    @Override
    public void setValueAt(Object aValue, int rowIndex, int columnIndex) {
        if(aValue != null){
            Source source = sources.get(rowIndex);
            switch(columnIndex){
                case 0:
                    source.setKom((String)aValue);
                    break;
                case 1:
                    source.setNir((String)aValue);
                    break;
                case 2:
                 source.setCot((String)aValue);
                    break;
                case 3:
                 source.setHor((String)aValue);
                    break;
                case 4:
                 source.setSp((String)aValue);
                    break;
                case 5:
                 source.setHh((String)aValue);
                case 6:
                 source.setDh((String)aValue);
                case 7:
                 source.setTt((String)aValue);
            }
        }
    }

    public void addSource(Source source) {
        sources.add(source);

        fireTableRowsInserted(sources.size() -1, sources.size() -1);
    }

    public void removeSource(int rowIndex) {
        sources.remove(rowIndex);

        fireTableRowsDeleted(rowIndex, rowIndex);
    }

aussi ma classe source:

 public class Source {
    private String nir;
    private String kom;
    private String cot;
    private String hor;
    private String sp;
    private String hh;
    private String dh;
    private String dd;
    private String tt;
    public Source(String nir, String kom, String cot, String hor, String sp, String hh, String dh, String dd, String tt) {
        super();

        this.nir = nir;
        this.kom = kom;
        this.cot = cot;
        this.hor = hor;
        this.sp = sp;
        this.hh = hh;
        this.dh = dh;
        this.dd = dd;
        this.tt = tt;
    }

    public String getNir() {
        return nir;
    }

    public void setNir(String nir) {
        this.nir = nir;
    }

    public String getKom() {
        return kom;
    }

    public void setKom(String kom) {
        this.kom = kom;
    }

    public String getCot() {
        return cot;
    }

    public void setCot(String cot) {
        this.cot = cot;
    }

    public String setHor() {
        return hor;
    }

    public void setHor(String hor) {
        this.hor = hor;
    }

    public String getSp() {
        return sp;
    }

    public void setSp(String sp) {
        this.sp = sp;
    }
     
    public String getHh() {
        return hh;
    }

    public void setHh(String hh) {
        this.hh = hh;
    }
    public String getDh() {
        return dh;
    }

    public void setDh(String dh) {
        this.dh = dh;
    }
    public String getDd() {
        return dd;
    }

    public void setDd(String dd) {
        this.dd = dd;
    }
    public String getTt() {
        return tt;
    }

    public void setTt(String tt) {
        this.tt = tt;
    }
}
