Description: Codes in an application could be regarded as the rules in dealing with data and processes. With codes, developers are able to guide the data and process them through different formulas. In any programming languages, codes will help determine the outcome of the application. However, not all rules imposed by codes are universal. Sometimes, there is information that shouldn’t be accepted. This type of information is dubbed as exception. With an exception, certain information will be treated differently. It could be used to alert the user that certain information is not accepted or will redirect the user to another webpage.
