java - 从 Jlist 中删除文件

Question

不知道我在这里做错了什么。我试图从我的目录中删除选定的文件，但它只是从列表中删除它。谢谢

  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();

我怀疑您想要获取 selectedIndex()。

我想你想获得选定的值:

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