hello @chandreshmaurya


                if (compareTo(arr[j], arr[j + 1]) > 0) {

                    string temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }

in this line they are using compare function .
now note one thing , they are performing swapping only when compareto return positive value.


        if (s1.length() > s2.length()) {
            return -1;
        } else {
            return 1;
        }

the control will reach to this if elsse only if while loop writen above will execute completely.
its compete execution indicates that one string is prefix or other string.
now for that case , we want to put larger string first and then smaller string.
so if larger string is already before smaller string no need to perform swap hence we are returning -1.
otherwise returning 1
