Linked List
Requirements
Implement a singly linked list:
- You may not use the
LinkedList
or ArrayList
class or any other predefined Java collections
- Your linked list must have a node inner class to represent each element
- Your linked list must have add, remove, contains, find, size, get, copy and sort methods
- Method definitions:
- add -- add an element to the list
- remove -- remove an element (specified by numeric index) from the list
- contains -- returns true if the element is in the list, false otherwise
- find -- returns the element's index if it is in the list, -1 otherwise
- size -- returns the current size of the list
- get -- returns the element at the specified index
- copy -- returns a new linked list containing the same values (look up deep versus shallow copy)
- sort -- sorts the list using your algorithm of choice. You must perform the sorting yourself (no fair using someone else's library)
Optional features
- implement your linked list as a generic class that can store any type of object
- Add a reverse method
- Add a slice method that returns a copy of a subset of the element of the list (eg slice(2,8) returns a new linked list containing elements #2,3,4,5,6,7 -- but not 8)
