我如何才能获得使用对象的数组类私有成员在main（）？

Question

我有4个私有成员一类电影。和我想用电影类对象数组访问此私有成员在main（）。我在电影一类4名成员分别电影的名字，电影导演，电影演员，电影收入。我已经创建了具有4个参数和一个串的方法来显示这个类成员细节一个参数的构造函数。现在，我想根据该收入为影片盈利排序从最高到最低，显示电影的名字。

class Movie {
    private String movieName;
    private String movieDirector;
    private String movieActor;
    private double movieEarning;

    Movie(String movieName, String movieDirector, String movieActor, double movieEarning) {
        this.movieName = movieName;
        this.movieDirector = movieDirector;
        this.movieActor = movieActor;
        this.movieEarning = movieEarning;
    }

    public String toString() {
        return "\n" + "Movie Name = " + movieName + "\n" + "Movie Director =" + movieDirector + "\n" + "Movie Actor = " + movieActor + "\n" + "Movie Earning = " + movieEarning;
    }
    public void movieData() {
        //Print movie name where director = Rohit Shetty
        if (movieDirector.equals("Rohit Shetty") || movieDirector.equals("rohit shetty"))
            System.out.println("Movie Name=" + movieName);
        //Print director name who earned between 300 - 500
        if (movieEarning > 300 && movieEarning < 500)
            System.out.println("Print Director Names who earns more than 300 crores= " + movieDirector);
        //print moive details where actor = salman khan && director=kabir khan
        if (movieActor.equals("Salman Khan") && movieDirector.equals("kabir khan")) {
            System.out.println("Print Movie Names = " + movieName);
            System.out.println("Print Movie Earning = " + movieEarning);
        }
        //print movie name whose actor name starts with s
        if (movieActor.startsWith("s"))
            System.out.println("Print Actor Name where movie name starts with 's' = " + movieName);

        //print movie name with order of highest earning to lowest earning
    }


}

public class MovieDemo2 {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String movieName;
        String movieDirector;
        String movieActor;
        double movieEarning;
        Movie[] movieObj;
        movieObj = new Movie[6];
        for (int i = 1; i < movieObj.length; i++) {
            System.out.print("Enter " + i + " movie name :");
            movieName = sc.next();
            sc.nextLine();
            System.out.print("Enter " + i + " movie director name :");
            movieDirector = sc.next();
            sc.nextLine();
            System.out.print("Enter " + i + " movie actor: ");
            movieActor = sc.next();
            sc.nextLine();
            System.out.print("Enter " + i + " movie earning: ");
            movieEarning = sc.nextDouble();
            sc.nextLine();
            movieObj[i] = new Movie(movieName, movieDirector, movieActor, movieEarning);
            System.out.println(movieObj[i]);

        }
        for (int i = 1; i < movieObj.length; i++) {
            movieObj[i].movieData();
        }
    }

}

我希望输出，当我进入电影的盈利六个时间的话，我将显示收入最高的为电影的最低收入最低的电影名称。为前，我输入值400,500,200,800,100那么这给了我谁赚高分到低分的电影名称的列表。
