question: public static Object normalizeIntAndLongValues ( String data , DataType actualDataType ) { if ( null == data ) { return null ; } try { Object parsedValue = null ; switch ( actualDataType ) { case INT : parsedValue = Integer . parseInt ( data ) ; break ; case LONG : parsedValue = Long . parseLong ( data ) ; break ; default : return data ; } if ( null != parsedValue ) { return data ; } return null ; } catch ( NumberFormatException ex ) { return null ; } }
target:  Below method will be used to basically to know whether any non parseable data is present or not. if present then return null so that system can process to default null member value.
