需求分析

在这里插入图片描述

首先每一部电影，都包含这部电影的相关信息，比如：电影的编号（id）、电影的名称（name）、电影的价格（price）、电影的分数（score）、电影的导演（director）、电影的主演（actor）、电影的简介（info）。

代码实现

JavaBean类

public class Movie {
    private int id;
    private String name;
    private double price;
    private  double score;
    private String director;
    private String actor;
    private String info;

    public Movie() {
    }

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

    public void setName(String name) {
        this.name = name;
    }

    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;
    }
}

操作类

public class MovieOperator {
    private Movie[] movies;

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

    public void findAllMovie(){
        for(int i=0;i<movies.length;i++){
            Movie m = movies[i];
            System.out.println("电影编号是："+m.getId());
            System.out.println("电影名称是："+m.getName());
        }
    }

    public void findById(int id){
        for(int i=0;i<movies.length;i++){
            Movie m = movies[i];
            if (m.getId() == id) {
                System.out.println("电影编号是：" + m.getId());
                System.out.println("电影名称是：" + m.getName());
                System.out.println("电影导演是：" + m.getDirector());
                System.out.println("电影价格是：" + m.getPrice());
                System.out.println("电影演员是：" + m.getActor());
                return;
            }
        }
        System.out.println("没有这部电影哦~~~");
    }
}

测试类

public class MovieTest {
    public static void main(String[] args) {
        System.out.println("--------------电影信息系统-----------------");
        System.out.println("操作功能请选择：1 或者 2");
        System.out.println("1：查询电影所有信息");
        System.out.println("2：更具电影编号查询电影信息");

        Movie[] movies = new Movie[4];
        movies[0] = new Movie(1,"水门桥", 38.9, 9.8, "徐克", "吴京","12万人想看");
        movies[1] = new Movie(2, "出拳吧", 39, 7.8, "唐晓白", "田雨","3.5万人想看");
        movies[2] = new Movie(3,"月球陨落", 42, 7.9, "罗兰", "贝瑞","17.9万人想看");
        movies[3] = new Movie(4,"一点就到家", 35, 8.7, "许宏宇", "刘昊然","10.8万人想看");

        Scanner scanner = new Scanner(System.in);
        MovieOperator movieOperator = new MovieOperator(movies);
        while (true){
            int command = scanner.nextInt();
            switch (command){
                case 1:
                    movieOperator.findAllMovie();
                    break;
                case 2:
                    System.out.println("请您输入查询的电影id:");
                    int id = scanner.nextInt();
                    movieOperator.findById(id);
                    break;
                default:
                    System.out.println("请输入正确序号~~");
            }
        }
    }
}
