Call class method from another class

So I am creating a Netflix based application for a school assignment. So yes this is homework. I created a userinterface that looks like the following

Code :

import java.io.IOException;
import java.util.Queue;
import java.util.Scanner;
 
 
public class UserInterface extends Users {
 
	public UserInterface(String userName, double accountNumber,
			Queue<Movie> playList, Queue<Movie> lastMovies) {
		super(userName, accountNumber, playList, lastMovies);
	}
 
	public static void main(String[] args){		
 
		Scanner keyboard = new Scanner(System.in);
		while(true){
 
			System.out.println("X) Exit");
			System.out.println("0) Create a new movie");
			System.out.println("1) Add Movie to your playlist");
			System.out.println("2) Upgrade your account");
 
			char c = keyboard.next().charAt(0);
			switch(c){
				case 'X':
					System.exit(0);
				case '0':
					createMovies;
				case '1':
					for(int i= 0; i < playList.size(); i++)
					System.out.println(playList);
					break;
				case '2':
					System.out.println("Small one time free of $10,000,000!");
					break;
			}	
		}
	}
}

so now what I am running into is the "case '0'" selection, where I am trying to just call "createMovies;" which is a method inside another class which looks like the following

Code :

import java.util.Date;
import java.util.Scanner;
 
public class createMovie 
{
	public Scanner keyboard = new Scanner(System.in);
 
	public static void main(String args[])
	{
 
	}
 
public void createMovies()
{
 
	String password = "adminpassword";
	boolean isAdmin = false;
	double inputPrice = 0;
	String inputMovie;
	String inputGenre;
	Date inputDate = new Date(); 
	String inputPassword;
 
	System.out.println("Enter Movie Title:");
	inputMovie = keyboard.nextLine();
	System.out.println("Enter Movie Genre:");
	inputGenre = keyboard.nextLine();
	System.out.println("Enter Admin Password:");
	inputPassword = keyboard.nextLine();
 
	passCheck(inputPassword, password, isAdmin);
	adminPower(isAdmin, inputPrice);
	Movie movies = new Movie(inputMovie, inputDate, inputGenre, inputPrice);
}
 
    public void passCheck(String inputPassword, String password, boolean isAdmin)
    {
    if(inputPassword == password)
    {
    	isAdmin = true;
    }
    else System.out.println("Sorry wrong password");
    }
 
    public void adminPower(boolean isAdmin, double inputPrice)
    {
	if (isAdmin == true)
		System.out.println("Enter Movie Price:");
	inputPrice = keyboard.nextDouble();
    }
 
}

and without adding more code to this post I will just say this creates a Movie object, that I will later have saved to a Movie selection linked list, and then allow the user to select movies out of that list.

So the problem is I can't get the function to call properly inside my interface class. How would I go about doing this? I tried creating a "createMovie movies = null;" and then passing it through the function like so "movies.createMovies(); but apparently that doesn't actually do anything because it is null.
