我尝试在netbeans中创建一个删除按钮但在成功删除后会出现警告。有什么可以吗？
private void jButtonDeleteActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
int index = jTableSurat.getSelectedRow();
// jika tidak ada
if (index == -1) {
JOptionPane.showMessageDialog(null, "Pilih baris yang akan di-delete!");
return;// maka proses dibatalkan
}
suratmasukkeluardomain suratmasuk=SuratModel.findOne(index);
SuratService.delete(suratmasuk);
bersih();
SuratModel.delete(index);
}
异常即将来临：
