Trouble with code

[galagali]

I have attached my assignment. For some reason, my code isn't working properly. I've looked through it, but I can't seem to find the error. If anyone can help me, I would greatly appreciate it.
Here is my code:
import java.util.*;

public class Project_11_1 {
public static void main(String[] args) {
System.out.println("Welcome to the Movie List Application");
System.out.println();
System.out.println("There are 100 movie in the list");
String choice = "y";
Scanner sc = new Scanner(System.in);

ArrayList<String> animated = new ArrayList<String>();
animated.add("One Piece");
animated.add("Bleach");
animated.add("Naruto");
animated.add("HellSing");
animated.add("Final Fantasy 7 Advent Child");


ArrayList<String>drama = new ArrayList<String>();
drama.add("Vertigo");
drama.add("The GodFather");
drama.add("Touch of Evil");
drama.add("21 day");
drama.add("The Searcher");

ArrayList<String> horror = new ArrayList<String>();
drama.add("IT");
drama.add("Alien");
drama.add("Resident Evil");
drama.add("Freddy");
drama.add("Jason");

ArrayList<String> scifi = new ArrayList<String>();
scifi.add("Star War");
scifi.add("Star Trek");
scifi.add("Stargate");
scifi.add("Merlin");
scifi.add("ET");

while(choice.equalsIgnoreCase("y"))
{
System.out.print("What category are you interested in?");
String movielist = sc.nextLine();
if (movielist == "animated")
{
System.out.println(animated);
}
else if (movielist == "drama")
{
System.out.println(drama);
}
else if (movielist == "horror")
{
System.out.println(horror);
}
else if (movielist == "scifi")
{
System.out.println(scifi);
}

System.out.print("Continue? y/n): ");
choice = sc.next();
}

}
}
