Topic: Doubly List for Name card (Java)

write a class NameCard.java which has

Data fields: name (String), age(int), company(String)

Methods:

Public String getName();

Public int getAge();

Public String getCom();

Public void setName(String n);

Public void setAge(int a);

Public void setCom(String c);

toString(): \\ can be used to output information on this name card

--------------------------------------------------------------------------------------------------------------------------------------------

write a class DoublyNameCardList.java, which is a doubly linked list and each node of the list a name card.

In the DoublyNameCardList.java:

Data field: Reference data type: head, which always references the first node of the doubly linked list Reference data type: tail, which aways references the last node of the doubly linked list int count, which is used to record the number of name cards in the list Method: public DoublyNameCardList(); // A constructor which can initialize the list: public void addEnd(NameCard x); // A method that allows you to place a value at the end of the list public void addHead(NameCard x); // A method that allows you to place a value at the begin of the list

public void add(int index, NameCard x); //A method that allows you to place a name card after the given location

public NameCard get(int index); //A method that allows you to retrieve a name card from a given location

public int size(); // A method that allows you to return the number of elements that is currently in the list

public void delete (index n); //A method that will remove a name card at the given index

Public boolean exist(NameCard n); // test if there has a name card in the list which has same content with n

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Now, write a driver program (the class with the public static void main(String[] args) method) name test.java to test the data structure you just created:

Fill in the list with 5 name card objects

print the list on the screen two times:

From head to tail

From tail to head

Call the method in the DoublyNameCardList class one by one, each method you called,

Print out a message to show what have you done

print out all the name cards in the list
