Question
Write a Java program which stores three values by using doubly linked list.
- Node class
4. stuID, stuName, stuScore, //data fields
5. constructor
6. update and accessor methods
- Singly linked list class which must has following methods:
4. head, tail, size// data fields
5. constructor
6. update and accessor methods
a. getSize() //Returns the number of elements in the list.
b. isEmpty( ) //Returns true if the list is empty, and false otherwise.
c. getFirstStuID( ), getStuName( ), getFirstStuScore( )
d. addFirst (stuID, stuName, stuScore)
e. addLast(stuID, stuName, stuScore)
f. removeFirst( ) //Removes and returns the first element of the list.
g. removeLast( ) //Removes and returns the first element of the list.
h. displayList( ) //Displays all elements of the list by traversing the linked list.
- Test class – initialize a doubly linked list instance. Test all methods of doubly linked list class.
