Question

In this assignment, you’ll decode Twitter messages that include Internet abbreviations, such as LOL and IRL. The starter program decodes two abbreviations.

step 3: --Convert the user's tweet to a decoded tweet, replacing the abbreviations directly within the tweet. You only need to replace the first instance of a particular abbreviation.

Here is an example program execution for step 3:

Entertweet:I'mgoingtohangoutwithmyBFFIRLtomorrow.

Decodedtweet:I'mgoingtohangoutwithmybestfriendsforeverinreallife tomorrow.

Another example execution for step 3 (user input is highlighted here for clarity):

Entertweet:So, IMHO he was going FTW, but I was so LOL that my BFF thought I was going to start crying IRL! Anyway, gotta go, TTYL... I'm going AFK.

Decodedtweet:So,in my humble opinion he was going forthe win, but Iwas so laughing out loud that my bestfriends forever thought I was going to start crying in real life! Anyway, gotta go, talk to you later... I'm going away from keyboard.

Explanation / Answer

Please find the below solution:

package org.learning.chegg.problem;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

public class TweetDecoder {

   private static Map<String, String> map;

   private static List<String> listOfAbbreviations;

   public static void main(String[] args) throws IOException {

       initialize();

       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));

       while(true){

           System.out.println("Enter Tweet: ");

           String tweet = bufferedReader.readLine();

           if(tweet.equals("exit")){

               break;

           }

           for(String abbr: listOfAbbreviations){

               if(tweet.contains(abbr)){

                   tweet = tweet.replaceAll(abbr, map.get(abbr));

               }

           }

           System.out.println("Decoded Tweet: "+tweet);

       }

       bufferedReader.close();

   }

   public static void initialize(){

       map = new HashMap<>();

       listOfAbbreviations = new ArrayList<String>();

       listOfAbbreviations.add("BFFIRL");

       map.put("BFFIRL", "bestfriendsforeverinreallife");

       listOfAbbreviations.add("IMHO");

       map.put("IMHO", "in my humble opinion");

       listOfAbbreviations.add("FTW");

       map.put("FTW", "for the win");

       listOfAbbreviations.add("LOL");

       map.put("LOL", "laughing out loud");

       listOfAbbreviations.add("BFF");

       map.put("BFF", "bestfriends forever");

       listOfAbbreviations.add("IRL");

       map.put("IRL", "in real life");

       listOfAbbreviations.add("TTYL");

       map.put("TTYL", "talk to you later");

       listOfAbbreviations.add("AFK");

       map.put("AFK", "away from keyboard");
