it is giving an exception java.sql.sqlexception nd i made a change in this i remove parseint method from line147 nd constants given in jformattedtextfield in line 52

Lines 55/57 are a very bad idea. If an exception is thrown you have chosen to ignore it completely. Unless you are expecting the exception and know that it's OK, you should always start out by printing all the info related to the exception:

catch (Exception ex) {
  ex.printStackTrace();
}
