Are two words anagrams? (you get what i mean...)

cool.java

class MyClass {
    public static void check_anagrams(String[] firstWords, String[] secondWords) {
        String characters = "abcdefghijklmnopqrstuvwxyz";
        int[] primes = {2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101};
        for (int i = 0; i < firstWords.length; i++){
            char a;
            char b;
            int firstWordValue = 1;
            int secondWordValue = 1;
            for (int j = 0; j < firstWords[i].length(); j++){
                if (j >= secondWords[i].length()) break; 
                a = firstWords[i].charAt(j);
                b = secondWords[i].charAt(j);
                firstWordValue *= primes[characters.indexOf(a)];
                secondWordValue *= primes[characters.indexOf(b)];
            }
            if (firstWordValue == secondWordValue){
                System.out.println(1);
            } else {
                System.out.println(0);
            }
        
        }
    }
}
