Java: Reads a text and prints two words

Java Basic: Exercise-227 with Solution

Most Frequent and Longest Words in Text

Write a Java program that reads a text (only alphabetical characters and spaces) and prints two words. The first one is the word which is frequently used in the text. The second one is the word with the most letters.

Note: A word is a sequence of letters which is separated by the spaces.

Input:

A text is given in a line with following condition:
a. The number of letters in the text is less than or equal to 1000.
b. The number of letters in a word is less than or equal to 32.
c. There is only one word which is arise most frequently in given text.
d. There is only one word which has the maximum number of letters in given text.
Input text: Thank you for your comment and your participation.
Output: your participation.

Sample Solution:

Java Code:

// Importing the Scanner class for user input
import java.util.Scanner;

// Main class named "Main"
class Main {
    
    // Main method to execute the program
    public static void main(String args[]) {
        // Creating a Scanner object for user input
        Scanner sc = new Scanner(System.in);

        // Reading a line of text and splitting it into an array of strings
        String strs[] = sc.nextLine().split(" ");
        
        // Variables to track the maximum length and frequency
        int max_Length = 0;
        int indexL = 0;
        int max_Frequency = 0;
        int indexF = 0;

        // Prompting the user to input a text in a line
        System.out.println("Input a text in a line:");

        // Loop to iterate through the array of strings
        for (int i = 0; i < strs.length; i++) {
            // Checking and updating the maximum length
            if (max_Length < strs[i].length()) {
                indexL = i;
                max_Length = strs[i].length();
            }

            // Counting the frequency of the current string
            int ctr = 0;
            for (int j = i; j < strs.length; j++) {
                if (strs[i].equals(strs[j])) {
                    ctr++;
                }
            }

            // Checking and updating the maximum frequency
            if (max_Frequency < ctr) {
                indexF = i;
                max_Frequency = ctr;
            }
        }

        // Prompting the user with the most frequent text and the word with the maximum number of letters
        System.out.println("Most frequent text and the word which has the maximum number of letters:");
        System.out.println(strs[indexF] + " " + strs[indexL]);
    }
}

Previous:Write a Java program to print mode values from a given a sequence of integers. The mode value is the element which occurs most frequently. If there are several mode values, print them in ascending order.
Next: Write a Java program that reads n digits (given) chosen from 0 to 9 and prints the number of combinations where the sum of the digits equals to another given number (s). Do not use the same digits in a combination.
