Sorted list

Code a doubly linked, sorted list (in ascending order). Each item of the list will just store an int.

You will need to code three classes: Node, SortedList, and GroupProject

The Node class has three instance variables, all private:

o An int, representing the value stored inside the Node

o A Node (next)

o Another Node (previous)

The methods to code are: constructor (at least one), accessors, mutators.

The SortedList class is a doubly linked list, sorted in ascending order.

It has two instance variables, both private:

o An int, representing he number of items in the list

o A Node, respesenting the head node in the list

The methods to code are:

o Insert: this method takes one parameter, an int; it has a void return value.

o Delete: this method takes one parameter, an int; it returns a Boolean value. If we were successful in deleting the item (i.e., the value of the parameter was found in the list), then we return true; if we were not successful, then we want to output a message that the value was not found, and therefore, not deleted, and return false.

o toString: this method takes no parameters and returns a String representation of the list.

o Constructor (at least one), and accessors and mutators as appropriate.

All methods should keep the list sorted in ascending order.



The GoupProject class contains the main method; it should do the following:

o Create a SortedList object reference

o Insert successively the values 25, 17,12, 21, 78, and 47 in the sorted list

o Output the contents of the sorted list using the toString method

o Delete from the sorted list the value 30, using the delete method ( obviously, 30 will not be found)

o Output the contents of the sorted list using the toString method.

o Delete from the sorted list the value 21, using the delete method

o Output the contents of the sorted list using the toString method

Your insert and delete methods should work properly in all possible scenarios: inserting in an empty list, inserting at the beginning of a list, inserting in the middle of the list, inserting at the end of the list, deleting from an empty list (cannot delete), deleting the first item in a list, deleting in the middle of a list, deleting the last item in a list.
