Description
1. Design a java interface called IDedObject which has following abstract functions.
int getID() //Returns the ID of the object
void printID() //Prints the details of the ID
2. Design a java class Magazine that implements IDedObject interface and has the
following class variables:
int magazineID
String magazineName
String publisherName
Implement suitable constructors, a printID function that prints all the variable values in
separate lines and getID() function that returns the magazineID. Add any access and other
functions necessary.
{Note all your data should be private and methods public inside the class)
3. Design a generic singly linked list java class (Give an appropriate name) to hold objects
of the generic type . This AnyType should extend IDedObject. The linked list
class must implement following member functions:
A constructor which generates an empty list .
void makeEmpty(); //empties the linked list
AnyType findID(int ID); // Get the generic type to get the particular id and
returns AnyType. Don’t remove the object from the list.
returns null if the list is empty or ID not found.
boolean insertAtFront( x); // insert at front of list or return false if that ID
already exists
AnyType deleteFromFront(); // delete and return the record at the front of the list or
return null if the list is empty
AnyType delete(int ID); // find and delete the record with the given ID or returns
null if it isn’t found
void printAllRecords(); // print all elements in the order they appear in the linked
list. if list is empty print appropriate message.
4. Write a java class to have the main function, create a linked-list to hold magazine type
objects. It should prompt the user to choice list of the following operations.
i. Make Empty
/// This Option makes the Linked list empty
ii. Find ID
/// print all details of the magazine ID, if it is in the
list , if not print appropriate message
iii. Insert At Front
/// Get the magazine details from the user and add it to the front of the list
iv. Delete From Front
///Print the first item on the list and then delete it.
v. Delete ID
/// Print particular IDed item and then delete it.
vi. Print All Records
// Print all the records in the list
vii. Done
///Quit the program. For every other option after task completion display
menu again.
Your program must read from the keyboard and print to the screen.

Additional Instructions:
Follow all project instructions given in elearning page. Include a README.txt file
explaining the IDE that you used. Permissible IDEs -> Netbeans, Eclipse and IntelliJ; Other IDEs
need permission from TA before project submission. If no IDE used and the program need to be
executed on the command prompt, give elaborate instructions on how to run and execute your
program. Your README file should also state what works and what doesn’t work and contain
sample run of your program.
Zip your files into one file before submitting, have the ‘readme’ file outside of zip file
(elearning lets multiple files in one submission). Use good style and layout and comment your
code well.
