Ethiopian Institute of Technology – Mekelle School of Computing Software Engineering Department Group assignment Fields ✓ ID ✓ Borrower Id ✓ Book Id ✓ Librarian Id ✓ Borrowed date ✓ Return date ✓ Status Have one class to set some rules or regulations. You can name it as Utils or Rule that have at least the following two constant, static, and final attributes ✓ MAX_BORROWED_BOOK which is 5 ✓ MAX_DAY_FOR_BOOK_TO_BE_RETURNED which is 3 days and add any other that you think important Notes that you should consider while developing the system

  • Use Encapsulation, any variable should be private and you should set a setter and getter method for all if necessary.
  • Interface and Abstract concepts should be implemented
  • You should have static variables, methods and blocks in the code in your own way
  • You should use super and this keywords in your code
  • You should Handle any Exception that might occur in your system and validate every input
  • When accepting password for Librarian it should be using System.console if possible else you can use any other Input Mechanisms.
  • Your program should display report in the console or write the data in the file according to your option. The system should let the user choose what to write in the file like ◦ Only student’s information ◦ Only Lecturer information ◦ Only Librarian Information ◦ Only Books Information ◦ Only Borrowed Books Information or History ◦ All Information
  • When you write a file use your own format to display. For example, to display list of students you can use ** List of Students ** Id Name Phone Department Year eitm/ur/0000/00 SSSSSS XXXXX YYYYYY DDDD eitm/ur/0000/00 CCCCC YYYYY BBBBBB IIIIIIII
  • You should be able to read from a file and store it your system. The system will have Import and Export mechanism. The file you write should be able to be read by the system and store in the system for manipulation purpose.
  • All your data should be stored in a HashMap ◦ HashMap is a Map based collection class that is used for storing Key & Values pairs. It is denoted as HashMap<Key, Value> or HashMap<K, V>. You have to import java.util.HashMap iin order to use HashMap class and methods. ▪ So, for this case you will have - HashMap<String, ArrayList> librerian = new HashMap<String, ArrayList>(); ◦ Here the String will be the keyword such as “digit”, “hard_copy”, “student”, “lecturer”, “librarian”, “borrow” and the value will be list of digit books, hard copy books, students, lecturers, librarians, borrowed books info.
  • The program you write should have the following options for each data
