Question

Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words.

Ex: If the input is:

5 hey hi Mark hi mark

the output is:

hey - 1 hi - 2 Mark - 1 hi - 2 mark - 1

Hint: Use two arrays, one array for the strings and one array for the frequencies

import java.util.Scanner;

public class LabProgram {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        // Read the number of words
        int numWords = input.nextInt();
        input.nextLine(); // Consume the newline character

        // Initialize arrays to store words and their frequencies
        String[] words = new String[numWords];
        int[] frequencies = new int[numWords];

        // Read and process the words
        for (int i = 0; i < numWords; i++) {
            String word = input.next();
            boolean found = false;

            // Check if the word is already in the array
            for (int j = 0; j < i; j++) {
                if (word.equalsIgnoreCase(words[j])) {
                    frequencies[j]++;
                    found = true;
                    break;
                }
            }

            // If the word is not found, add it to the arrays
            if (!found) {
                words[i] = word;
                frequencies[i] = 1;
            }
        }

        // Output words and their frequencies
        for (int i = 0; i < numWords; i++) {
            if (words[i] != null) {
                System.out.println(words[i] + " - " + frequencies[i]);
            }
        }
    }
}
