javax.swing.JTable中;记录验证原因性能问题
我试图使用for循环验证来自JTable的每个记录，当JTable有很多记录时，它需要花费很多时间，请建议我更好的方法。 请在下面找到示例代码段。谢谢提前。

            JTable tblReceipt = getTblReceive();
                    tblReceipt.removeEditor();
                    boolean allLineCheck = true;


                    for (int row = 0; row < tblReceipt.getRowCount(); row++)
                    {
                        String issueQty = (String) tblReceipt.getValueAt(row, 5);
                        String receiveQty = (String) tblReceipt.getValueAt(row, 6);
                        String itemNo = (String) tblReceipt.getValueAt(row, 0);
                        double dIssueQty = Common.toDouble(issueQty);
                        double dReceiveQty = Common.toDouble(receiveQty);


                        double qty = 1.0;// initial one quantity
                        qty = qty / Math.pow(10, itmDecimal);

                        if (dReceiveQty > dIssueQty)
                        {
                            getProgressBar().setVisible(false);
                            Common.displayConfirmDialog()

                            // Qty exceeds the available qty


                        }
                        else if (itmDecimal == 0 && (dReceiveQty >= 0.0000001 && dReceiveQty <= 0.1))
                        {

                            Common.displayConfirmDialog();


                            // Invalid quantity

                            return false;
                        }

                    }
