You could use indexOf to get the sum od i's

see below

public class Main {

public static void main(String[] args) {
String word = "His ice-cream in his pocket";

int i = -1;
int sum = 0;
System.out.println();
while ((i=word.indexOf("i",i+1)) != -1) {
++sum;
}

System.out.println("number of i in '" + word+ "' is " + sum);
}
}
