这段程序会输出什么？

public class Main {
    public static void main(String[] args) {
        String status = "ready";
        String folded = "re" + "ady";
        String copied = new String(status);

        status.toUpperCase();

        System.out.println(status);
        System.out.println(status == folded);
        System.out.println(status.equals(copied));
        System.out.println(status == copied);
    }
}
