Answer 1

as in log :

NumberFormatException: unable to parse 'null' as integer

means you are trying to convert an null value to integer . before converting String value to integer check it for null to empty and use try/catch for handling NumberFormatException .

int  intnum=0;
if (strvalue !=null && !"".equals(strvalue) ){
     try {
           int  intnum = Integer.parseInt(strvalue);

         } catch (NumberFormatException e) {
            intnum=0;
            System.out.println(e.getMessage());
        }
}
else{
intnum=0;
}
