Object-Oriented Programming with Java, part I – Exercise 55

This program compares two words to see if the first one is inside the second one and then prints the result.

My Code

import java.util.Scanner;

public class WordInsideWord {

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

        System.out.print("Type the first word: ");
        String firstWord = reader.nextLine();

        System.out.print("Type the second word: ");
        String secondWord = reader.nextLine();

        int index = firstWord.indexOf(secondWord);

        if (index == -1) {
            System.out.println("The word " + secondWord + " is not found in the word " + firstWord + ".");
        } else {
            System.out.println("The word " + secondWord + " is found in the word " + firstWord + ".");
        }

    }
}

Model Code

import java.util.Scanner;

 

public class WordInsideWord {

 

    public static void main(String[] args) {

        Scanner reader = new Scanner(System.in);

        System.out.print("Type the 1. word:");

        String word1 = reader.nextLine();

        System.out.print("Type the 2. word:");

        String word2 = reader.nextLine();

 

        if (word1.indexOf(word2) != -1) {

            System.out.println("The word '" + word2 + "' is found in the word '" + word1 + "'");

        } else {

            System.out.println("The word '" + word2 + "' is not found in the word '" + word1 + "'");

        }

    }

}

Comments

Mine is pretty much the same as the Model Code except that this time I have introduced a new variable to make it easier to read and they have not.
