Action listener JList and create Jtable based on Jlist selection

Question

I have Jlist that have list of tables . I want the user to select table from the JList and this should change the values in the JTable that being created next to JTable. However, I get exception "Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException"

I know this exception result of the object not being created.

If I let the program read the first Table from JList it will work fine as soon as I select different value from JList and give me Exception in thread "AWT-EventQueue-0" java.lang.IndexOutOfBoundsException.

My listener is simply

table.setModel(New TableModel):

Answer 1

It was problem with directory because JTable read from files . here is my code for the listener if any body interested. CSVReader is AbstractTableModel that read CSV file I don't expect answer.

 class SharedListSelectionHandler implements ListSelectionListener {
        public void valueChanged(ListSelectionEvent e) {
 ListSelectionModel lsm = (ListSelectionModel)e.getSource();
if (!lsm.isSelectionEmpty()) {

CSVReader newCSV = new CSVReader((String)FileList.getSelectedValue());
               table.setModel(newCSV);


}
