Write a method that converts the string cdabcdji to abcdij, that is, removes duplicate characters and outputs the result in sorted order:

public class Main {
    public static void main(String[] args) {
        String input = "cdabcdji";
        String result = removeDuplicatesAndSort(input);
        System.out.println(result);
    }

    private static String removeDuplicatesAndSort(String str) {
        // ...

}
