netbeans 表达式的非法开始，不确定是什么问题[关闭]

Question

下面的代码在 main 方法中给出了一个错误，说它是一个表达式的非法开始。谁能告诉我是否有任何语句未正确终止或缺少任何括号？还有什么问题？这是在 netbeans 上，我不是程序员。行话也不行。这是我的管理课程讲师的剪切粘贴作业。感谢您的任何帮助！！！

    private void AddButtonActionPerformed(java.awt.event.ActionEvent evt) {

         String url = "jdbc:ucanaccess://" + path;
         Connection c= DriverManager.getConnection(url);
          Statement stinsert=c.createStatement();
          String Sql = "Insert into Students(StudentName,StudentAge,EnrollmentDate,EnrolledCLasses,StudentAddress,StudentContactNumber,TeacherComment) Values (";
          Sql = Sql +"'" + txtSName.getText() +"','";

不是程序员，所以我尝试在不同的行上添加分号和括号，但没有任何效果。再次感谢你！

Answer 1

在 catch 语句之后你缺少 2 个右大括号：

       catch (Exception E) {
    /**
     * @param args the command line arguments
     */

应该：

        } catch (Exception E) {

        }
    }
    
    /**
     * @param args the command line arguments
     */
