Delete File from Jlist

Question

Don't know what I'm doing wrong here. I'm trying to delete the selected file from my directory but it's only deleting it from the list. Thanks

  private void deletecustButtonActionPerformed(java.awt.event.ActionEvent evt) {
    DefaultListModel model = (DefaultListModel) customerList.getModel();

    int selectedIndex = customerList.getSelectedIndex();
    File customer = new File("Customers/" + selectedIndex);
    if (selectedIndex != 1) {
      customer.delete();
      model.remove(selectedIndex);
    }
  }

Answer 1

 int selectedIndex = customerList.getSelectedIndex();

I doubt you want to get the selectedIndex().

I would think you want to get the selected value:

String fileName = customerList.getSelectedValue().toString();
File customer = new File("Customers/" + fileName);

Answer 2

If you want to delete several selected files of the list with one click:

private void deletecustButtonActionPerformed(java.awt.event.ActionEvent evt) {
    String fileName;
    DefaultListModel model = (DefaultListModel) customerList.getModel();
    // Get the number of selected files 
    // (corresponding of the size of the int[] customerList.getSelectedIndices() ).
    int numberOfSelections = customerList.getSelectedIndices().length;
    int selectedIndex=0;
    File customer = null;
    // Loop to remove all selected items except your n#1 cust.
    // We begin at the end because the list will be "cut" each turn of the loop
    for(int i = numberOfSelections-1; i >=0 ; i--){
        // Get the selected index
        selectedIndex = customerList.getSelectedIndices()[i];
        if (selectedIndex != 1) {
            fileName = model.getElementAt(selectedIndex);
            customer = new File("Customers/" + fileName );
            customer.delete();
            model.remove(selectedIndex);
        }          
    }
  }
