Question
* This Java Program inputs a list of words from a Text file and separates it with whitespace
* It puts each word from the Txt file into an array with a count of how many times it appears
* When completed, the array is output into a text file named input3.out
*/
public class Word
{
String word;
int count;
public Word(String word) {
this.word = word;

Can you plea sh metoity m fe Modify the code to implement the list of words from the text file as a sorted doubly-linked list. So, basically, as a new word is added to the list, search the list and find where it belongs in the list. If it doesn't exist, add it in the correct location and set the word counter to 1. Example 1: Need to put "lion" in the list. The existing list is: lamb->lunch lion is> than lamb butExplanation / Answer
