Question
Suppose that you are working for an online service dedicated to animal lovers. Visitors
to your website can post comments and you desire to ‘like’ any comments that ONLY
includes animals like cat, dog, horse, or bird.
Complete the program (shown below) that reads a string of characters from the
keyboard and determines whether it contains one or more of these animals. For
example, if the user enters
My dog is as big as a horse
Your program will output to the display
I like this user because he likes: dog horse
If the user’s input does not include an animal, the program will output to the display
I don’t like this user
Upper and lowercase does not matter. Therefore, dog and dOg to same.
Following is the program to be completed. Nothing needs to be done to the main
method, however the checkForLikes method must be completed.
import java.util.Scanner;
/**
* Project 2 - Animal Lover
* @author
*/
public class Project2 {
public static void main(String[] args) {
//The following is for testing
checkForLikes("I have a Dog and a cat");
checkForLikes("I don't have an animal");
//The following is for user input
Scanner keyboard = new Scanner(System.in);
String input = keyboard.nextLine();
checkForLikes(input);
}
public static void checkForLikes(String message) {
// Your code goes here
}
}

String animals = "";
message = message.toLowerCase();
for(String a : animalList) {
if(message.contains(a))
