plz debug and fix it, show the screenshot of the output and code when its finish
I am Lawrence
Lawrence is a student
Who is Lawrence
He is Lawrence
here is my main method:
import java.util.*;
import java.io.*;
public class TwitterMain {
public static void main(String[] args) throws FileNotFoundException {
Scanner input = new Scanner(new File("hi.txt")); // Make Scanner over tweet file
List<String> tweets = new ArrayList<>();

// TODO: Call and display results from getMostFrequentWord and your
// creative method here
String mostFrequentWord = trends.getMostFrequentWord();
System.out.println("The most frequent word is: " + mostFrequentWord);

}
Here is my TweetBot method:
import java.util.*;
import java.io.*;
public class TweetBot {

This is my TwitterTrends method:
import java.util.*;

public class TwitterTrends {
// TODO: Your Code Here
private TweetBot bot;
private List<String> tweets;

for (int i = 0; i < numTweets; i++) {
String tweet = bot.nextTweet();
String word = "";
for (int j = 0; j < tweet.length(); j++) {
char c = tweet.charAt(j);
if (Character.isLetter(c)) {
word += c;
} else if (!word.isEmpty()) {
String lowerCaseWord = word.toLowerCase();
if (frequencies.containsKey(lowerCaseWord)) {
frequencies.put(lowerCaseWord, frequencies.get(lowerCaseWord) + 1);
} else {
frequencies.put(lowerCaseWord, 1);
}
word = "";
}
}
if (!word.isEmpty()) {
String lowerCaseWord = word.toLowerCase();
if (frequencies.containsKey(lowerCaseWord)) {
frequencies.put(lowerCaseWord, frequencies.get(lowerCaseWord) + 1);
} else {
frequencies.put(lowerCaseWord, 1);
}
}
}
String mostFrequentWord = "";
int maxFrequency = 0;
// Find the most frequent word
for (String word : frequencies.keySet()) {
int frequency = frequencies.get(word);
if (frequency > maxFrequency) {
mostFrequentWord = word;
maxFrequency = frequency;
}
}
return mostFrequentWord;
}
}
Solution:
The issue is that the implementation of getMostFrequentWord() method is not considering the stop words like "is" and "a" which have a high frequency in the text, but do not contribute to the topic of the text.
One way to fix this is to use a stop words list and exclude them from the frequency count. Here's an updated implementation of the TwitterTrends class:
