Hi every one. i have a jtable that correctly read data frome file and show them in own. I want to add a "Delete" button that when select a row and clicked button, row must deleted. But, when i click the button, row dont deleted and a ArrayOutOutBoundsException occur.

my whole code is this:

    import java.awt.event.ActionEvent;  
    import java.awt.event.ActionListener;  
    import java.io.BufferedReader;  
    import java.io.FileInputStream;  
    import java.io.InputStreamReader;  
    import java.util.StringTokenizer;  
    import java.util.Vector;  
    import javax.swing.JButton;  
    import javax.swing.JFrame;  
    import javax.swing.JPanel;  
    import javax.swing.JScrollPane;  
    import javax.swing.JTable;  
    import javax.swing.table.AbstractTableModel;  

    public class RemoveRow extends AbstractTableModel{  

    Vector data;  
    Vector columns;  
    public RemoveRow() {  

            String line;  
            data = new Vector();  
            columns = new Vector();  
            try {  
            FileInputStream fis = new FileInputStream("D:\\AllUserRecords.txt");  
            BufferedReader br = new BufferedReader(new InputStreamReader(fis));  
          StringTokenizer st1 = new StringTokenizer(br.readLine(), " ");  
                  while (st1.hasMoreTokens())  
                   columns.addElement(st1.nextToken());  
                    while ((line = br.readLine()) != null) {  
                           StringTokenizer st2 = new StringTokenizer(line, " ");  
                            while (st2.hasMoreTokens())  
                                    data.addElement(st2.nextToken());  
                    }  
                    br.close();  
            } catch (Exception e) {  
                    e.printStackTrace();  
            }  
    }  

        public int getRowCount() {  
            return data.size() / getColumnCount();  
    }  

    public int getColumnCount() {  
            return columns.size();  
    }  

    public Object getValueAt(int rowIndex, int columnIndex) {  
            return (String) data.elementAt((rowIndex * getColumnCount())  
                            + columnIndex);  
    }  
    public static void main(String[] args){  

        final RemoveRow rR1=new RemoveRow();  
        JFrame frame=new JFrame();  
        final JTable table=new JTable();  
        table.setModel(rR1);  
        JPanel panel=new JPanel();  
        JButton button1=new JButton("Delete");  

        button1.addActionListener(new ActionListener() {  

                public void actionPerformed(ActionEvent e) {                 
                    table.remove(table.getSelectedRow());  
                }  
            });  
            panel.add(button1);  
            panel.add(new JScrollPane(table));  
            frame.add(panel);  
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  
            frame.setBounds(10, 10, 600, 300);  
            frame.setVisible(true);  
    }  

    }

please repair my code!

Thanks!
