Aktualisieren einer JTable ohne mehr als einmal angezeigt

Question

Ich habe eine JTable, die durch Klicken auf eine Schaltfläche aktualisiert wird. Aber jedes Mal, wenn ich auf die Schaltfläche "Aktualisieren" klicke, wird das gleiche Ergebnis erneut angezeigt.

* Für exemple ersten Mal, dass ich Sie auf das angezeigte Ergebnis auf jtable auf aufzufrischen:

Name

Nachnamen

* das zweite Mal, dass ich das Ergebnis klicken Sie aktualisieren wird:

Name

Nachnamen

Name

Nachnamen

das gleiche Ergebnis dupliziert. Wie soll ich das Ergebnis einmal erhalten, obwohl ich mehrmals auf die Schaltfläche "Aktualisieren" klicke?

} 

und das ist die Klasse, die Zeilen in die jtable fügt hinzu: worklist.java

import javax.swing.table.DefaultTableModel;

public class worklist extends ModalityWorklist{ 
    public worklist(){ 

    } 
    public static void main(String[] args,String Name,String ID) { 

    DefaultTableModel model=(DefaultTableModel)modalityWorklist.getModel(); 
     model.setColumnIdentifiers(new String[]{"Patient ID","Patient Name"}); 
     row=new Object[2]; 
     row[0]=ID; 
     row[1]=Name; 
     model.addRow(row); 


    } 

} 

Answer 1

Ich habe, um die Zeilen zu löschen und zeigt sie wieder

int rowCount = model.getRowCount(); 
      for (int i = rowCount - 1; i >= 0; i--) { 
       model.removeRow(i); 
      } 

Answer 2

Sieht aus wie, wenn Sie die Tabelle erneuern, die Sie sind Duplizieren Sie die Elemente in Ihrem Modell. Können Sie uns den Code zeigen, den Sie ausführen, wenn Sie auf "Aktualisieren" klicken?

Ihre Refresh-Schaltfläche sollte auf dem JTable-Instace aufrufen. Das sollte alles sein, wenn Sie das Modell aktualisieren, sollte die Tabelle korrekt aktualisiert werden.
