JBDC MYSQL preparestatement not working

Hi Guys, can anyone help me solve this issue? i tried on other method it works but I don’t know why it can’t work over here. Below is my code

 public void extractLog(String logString)
    {
        PreparedStatement pstmtRunTime = null;
        StringTokenizer stToken = new StringTokenizer(logString);
        String currentToken;
        String a="1";
        String b="2";
        String c="3";
        String d="4";
        String e="5";
        boolean update= false;
        LG_updateID="0";
        int count=1;
        currentToken=stToken.nextToken().trim();
        LG_updateID = currentToken;

        while(stToken.hasMoreTokens())
        {
            currentToken=stToken.nextToken().trim();
            count++;
            
            if(LG_updateID.equals("1")) //string for bus loading/unloading
            {
                if(count==4)
                {
                    LG_Time=currentToken;
                    System.out.println(currentToken);
                }
                else if(count==7)
                {
                    LG_busID=currentToken;
                    System.out.println(currentToken);
                }
                else if(count==10)
                {
                    LG_numPassenger_Board=currentToken;
                    System.out.println(currentToken);
                }
                else if(count==13)
                {
                    LG_numPassenger_Alight=currentToken;
                    System.out.println(currentToken);
                }
                else if(count==17)
                {
                    LG_busStopID=currentToken;
                    System.out.println(currentToken);
                    update = true;
                }
                //update
              /*  String SQLRun_Time = "insert into runtime_update (LG_updateID,LG_Time,LG_busID,LG_numPassenger_Board,LG_numPassenger_Alight,LG_busStopID)"

                if(update==true)
                {
                    System.out.println("test");

                    try
                    {
                    //stmt.executeUpdate(SQLRun_Time);
                        pstmtRunTime = con.prepareStatement(SQLRunTime);
                        System.out.println("test2");
                        pstmtRunTime.setString(1, LG_updateID);

                        pstmtRunTime.setString(10, LG_Time);
                        pstmtRunTime.setString(11, LG_TLO_NSStatus);
                        pstmtRunTime.setString(12, LG_TLO_EWStatus);
                      //pstmtRuneTime.setInt(13, LG_busStopID);
                                                               
                        pstmtRunTime.executeUpdate();
                        update =false;
                    }
                    catch (Exception ex)
                    {
                        update = false;
                        System.out.println("Fail to update");
                    }
