PLEASE HELP IN JAVA:

This is an exercise in using the java LinkedList class.

Using input file words.txt , create a LinkedList BUT you must NOT add a word that is already in the list and you MUST add them in the order received to the end of the list.

For example, if your input was cat, cat, dog, mouse, dog, horse

your list would now contain cat, dog, mouse, horse. And the head of the list would be cat, and the tail would be horse. Note: it is NOT sorted.

This list represents a code, and the code for one word is the next word in the list. So the code for cat is dog and the code for mouse is horse, and the code for horse is cat(go round to the head of the list).

Now ask your user for a phrase (input from the keyboard) and output the coded phrase. In the above example if the input was "mouse cat" the output would be "horse dog".

How do you know if you have the correct output? I suggest you make your own (small) input file so you can test it.

Rubric:

* use of try/catch

*use of while loop to collect inout

* no duplicates put into list

* prompt user for phrase

* code the phrase

* correct output
