We want to create a "Greeting Counter" that tell us how many times you entered a greeting. Improve the program that takes any number of words in a single line as input, and outputs the number of greetings. Valid greetings to count are "Hi", "Hello" and "Hey". Different cases are allowed. The input ends with -1 on a line alone. Ex: If the input is:

Hi World Hey -1

then the output is:

Greetings: 2

So my answer keeps getting infinite loop errors and I'm not sure where I'm going wrong.

import java. util. Scanner;

public class GreetCounter {

public static void main(String[] args) {

Scanner scnr = new Scanner(System. in);

String input = scnr. nextLine();

int i = 1;

while(!input. equals("-1")) {

if (input. equals("Hi") || input. equals("Hello") || input. equals("Hey")) {

i +=0;

}

}

System. out. print("Greetings: ");

System. out. println(i);

}

}
