Java - Display A List Of Files Name From Folder To JTable

Java JTable Code - Populate A Jtable With A List Of Files Names From A Folder In Java Using NetBeans .

                                                                           


In this java Tutorial we will see How To Populate A JTable With Files Names From A Folder In Java Using NetBeans .






- to do that we will create a function and call it "getFilesName" :

   public void getFilesName()
    {
        File file = new File(getClass().getResource("/java_tutorials/products").getFile());
        File[] files = file.listFiles();
        DefaultTableModel model =    (DefaultTableModel)jTable_Files_Name.getModel();
        model.setColumnIdentifiers(new String[]{"Files Names"});
        Object[] row = new Object[1];
        for(int i = 0; i < files.length; i++)
        {
            row[0] = files[i].getName();
            model.addRow(row);
        }
    }
