JBStonehenge, Melanie_Green, paulcw thank u so much for ur support!!!!
I did many changes in my code, and I think in a simple way... I can sort the strings, but I'm having problems to sort the integers from the array I created..
I read a lot of sorting and this was the best I could do, please can you change my code to sort the integers?
Thank u people!
Here it is my code:

import java.util.*;

     public static void main(String[] args) {
          MyMovies Movies = new MyMovies();

     private static int numberOfMovies = 0;
     private static Movie[] array = new Movie[MAX_SIZE];
     public void runEverything(){
          Scanner input = new Scanner(System.in);
          while (true) {
               Menu();

               try {
                    option = Integer.parseInt(input.nextLine());
               } catch (NumberFormatException e) {
                    System.out.println("You must enter a number!");
                    continue;
switch (option) {

                    addMovie(input);
