Description:

This program shows the registration form for the online banking application. In this application any user is assigned with 2 roles and their time constraint is also specified by the administrator of the bank. All these details are stored in an XML file instead of storing in the database. User’s input is concatenated with in the tags. Only with the tag you can access the details of that user. Based on the DTD (Document Type Definition) all the fields are stored in the XML file. XML parser packages are used to get the content of the specified tag name.FileReader and BufferedReader are used for getting the existing values.PrintWriter is used to write the contents into the file.
