请问大家有什么改正办法没有 谢谢了
一下是部分代码请看看
        if (e.getSource() == jButton2) {
            int rows = jTable1.getRowCount();
            String c1=null,c2=null,c3=null,c4=null,c5=null,c6=null,c7=null,c8=null,c9=null,c10=null;
            for (int i = 1; i < rows; i++) {
                 c1 = (String) jTable1.getValueAt(i, 1);
                 c2 = (String) jTable1.getValueAt(i, 2);
                 c3 = (String) jTable1.getValueAt(i, 3);
                 c4 = (String) jTable1.getValueAt(i, 4);
                 c5 = (String) jTable1.getValueAt(i, 5);
                 c6 = (String) jTable1.getValueAt(i, 6);
                 c7 = (String) jTable1.getValueAt(i, 7);
                 c8 = (String) jTable1.getValueAt(i, 8);
                 c9 = (String) jTable1.getValueAt(i, 9);
                 c10 = (String) jTable1.getValueAt(i, 10);
            }

            Connection con = null;
            String sql = null;
            ResultSet rs = null;
            Statement stmt = null;

            try {
                Class.forName(
                        "com.microsoft.jdbc.sqlserver.SQLServerDriver");
                con = DriverManager.getConnection(
                        "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=jinxiaocun",
                        "sa",
                        "");
                stmt = con.createStatement();
                sql="insert into shangpindan values("
                    + c1 + ","
                    + c2 + ","
                    + c3 + ","
                    + c4 + ","
                    + c5 + ","
                    + c6 + ","
                    + c7 + ","
                    + c8 + ","
                    + c9 + ","
                    + c10 + ")";
                stmt.executeUpdate(sql);
                System.out.print("aaaa");
            } catch (Exception ex) {

问题已经解决
c1 = (String) jTable1.getValueAt(i, 1);
改为c1 = String.ValueOf(jTable1.getValueAt(i, 1);)
就可以了
