面对对象基础案例

模仿电影信息系统

需求：

• 展示系统中的全部电影（每部电影展示：名称，价格）。
• 允许用户根据电影编号（id）查询出某个电影的详细信息。

Movie类

public class Movie {
    private int id;         //id
    private String namel;   //电影名
    private double price;   //价格
    private double score;   //评分
    private String director;//导演
    private String actor;   //主演
    private String info;    //观看人数

    public Movie() {
    }

    public Movie(int id, String namel, double price, double score, String director, String actor, String info) {
        this.id = id;
        this.namel = namel;
        this.price = price;
        this.score = score;
        this.director = director;
        this.actor = actor;
        this.info = info;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getNamel() {
        return namel;
    }

    public void setNamel(String namel) {
        this.namel = namel;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public double getScore() {
        return score;
    }

    public void setScore(double score) {
        this.score = score;
    }

    public String getDirector() {
        return director;
    }

    public void setDirector(String director) {
        this.director = director;
    }

    public String getActor() {
        return actor;
    }

    public void setActor(String actor) {
        this.actor = actor;
    }

    public String getInfo() {
        return info;
    }

    public void setInfo(String info) {
        this.info = info;
    }
}

MovieOperator类

public class MovieOpertor {
    private Movie[] movies;

    public MovieOpertor(Movie[] movies) {
        this.movies = movies;
    }

    /** 1.展示系统全部电影信息 **/
    public void printAllMovies(){
        System.out.println("----------系统全部电影信息如下：-----------");
        for (int i = 0; i < movies.length ; i++) {
            Movie m = movies[i];
            System.out.println("编号："+m.getId());
            System.out.println("名称："+m.getNamel());
            System.out.println("价格："+m.getPrice());
            System.out.println("-------------------------------------");
        }
    }

    /** 2.根据电影编号查询电影详细信息 **/
    public void searchMovieById(int id){
        for (int i = 0; i < movies.length ; i++) {
            Movie m = movies[i];
            if (m.getId() == id){
                System.out.println("该电影详情如下：");
                System.out.println("编号："+m.getId());
                System.out.println("名称："+m.getNamel());
                System.out.println("价格："+m.getPrice());
                System.out.println("评分："+m.getScore());
                System.out.println("导演："+m.getDirector());
                System.out.println("主演："+m.getActor());
                System.out.println("观看人数："+m.getInfo());
                return;
            }
        }
        System.out.println("没有该电影信息");
    }
}

Test类

public class Test {
    public static void main(String[] args) {
        //1.设计一个电影类\
        //2.设计一个电影操作类
        //3.准备全部电影数据

        Movie[] movies = new Movie[3];
        movies[0] = new Movie(1,"水门桥",38.9,9.8,"徐克","吴京","13万人想看");
        movies[1] = new Movie(2,"出拳把",39,8.8,"唐晓白","田宇","3.5万人想看");
        movies[2] = new Movie(3,"月球陨落",42,7.9,"罗兰","贝瑞","17万人想看");
        //4.创建一个电影操作类
        MovieOpertor opertor = new MovieOpertor(movies);

        while (true) {
            System.out.println("==电影信息系统==");
            System.out.println("1.查询电影全部信息");
            System.out.println("2.根据id查询某个电影详细信息");
            System.out.println("请您输入操作命令");
            Scanner s = new Scanner(System.in);
            int sc = s.nextInt();
            switch (sc) {
                case 1:
                    opertor.printAllMovies();
                    break;
                case 2:
                    System.out.println("请输入您查询的电影id：");
                    int id = s.nextInt();
                    opertor.searchMovieById(id);
                    break;
                default:
                    System.out.println("您输入的操作有问题");
            }
        }
    }
}
