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、平分）。
允许用户根据电影编号（id）查询出某个电影的详细信息。

1. 将JavaBean数据类封装好

java 复制代码

package com.liujintao.domain;

/**
 * JavaBean
 */
public class Movie {
    private int id;
    private String title;
    private String time;
    private double score;
    private String area;
    private String type;
    private String director;
    private String starring;


    public Movie() {
    }

    public Movie(int id, String title, String time, double score, String area, String type, String director, String statting) {
        this.id = id;
        this.title = title;
        this.time = time;
        this.score = score;
        this.area = area;
        this.type = type;
        this.director = director;
        this.starring = statting;
    }

    /**
     * 获取
     * @return id
     */
    public int getId() {
        return id;
    }

    /**
     * 设置
     * @param id
     */
    public void setIdl(int id) {
        this.id = id;
    }

    /**
     * 获取
     * @return title
     */
    public String getTitle() {
        return title;
    }

    /**
     * 设置
     * @param title
     */
    public void setTitle(String title) {
        this.title = title;
    }

    /**
     * 获取
     * @return time
     */
    public String getTime() {
        return time;
    }

    /**
     * 设置
     * @param time
     */
    public void setTime(String time) {
        this.time = time;
    }

    /**
     * 获取
     * @return score
     */
    public double getScore() {
        return score;
    }

    /**
     * 设置
     * @param score
     */
    public void setScore(double score) {
        this.score = score;
    }

    /**
     * 获取
     * @return area
     */
    public String getArea() {
        return area;
    }

    /**
     * 设置
     * @param area
     */
    public void setArea(String area) {
        this.area = area;
    }

    /**
     * 获取
     * @return type
     */
    public String getType() {
        return type;
    }

    /**
     * 设置
     * @param type
     */
    public void setType(String type) {
        this.type = type;
    }

    /**
     * 获取
     * @return director
     */
    public String getDirector() {
        return director;
    }

    /**
     * 设置
     * @param director
     */
    public void setDirector(String director) {
        this.director = director;
    }

    /**
     * 获取
     * @return statting
     */
    public String getStarring() {
        return starring;
    }

    /**
     * 设置
     * @param starring
     */
    public void setStarring(String starring) {
        this.starring = starring;
    }

}

2.业务逻辑类

java 复制代码

package com.liujintao.test;

import com.liujintao.domain.Movie;

import java.util.Scanner;

public class MovieService {
    // 提升为成员变量，并合理隐藏
    private Movie[] movies;
    private Scanner sc;
    /**
     * 带参构造器：获取JavaBean中数据
     *
     */
    public MovieService(Movie[] movies) {
        this.movies = movies;
    }

    /**
     * 启动电影信息管理系统
     */
    public void start() {

        this.sc = new Scanner(System.in);
        lo:
        while(true) {
            System.out.println("----------电影信息系统----------");
            System.out.println("请输入您的选择");
            System.out.println("1.查询全部电影信息");
            System.out.println("2.根据id查询电影信息");
            System.out.println("3.退出");

            int choice = sc.nextInt();

            switch(choice) {
                case 1:
                    queryMoviesInfo();
                    break;
                case 2:
                    queryMoviesById();
                    break;
                case 3:
                    System.out.println("退出");
                    break lo;
                default:
                    System.out.println("您的输入有误！");
                    break;
            }
        }
    }


    /**
     * 通过编号：展示电影所有信息
     */
    private void queryMoviesById() {
        System.out.println("请输入电影的id号：");
        int id = sc.nextInt();

        for (int i = 0; i < movies.length; i++) {
            if (movies[i].getId() == id) {
                System.out.println("编号:" + movies[i].getId() + "-电影名：-" + movies[i].getTitle() + "-上映时间：-" + movies[i].getTime() + "-评分：-" + movies[i].getScore() + "-地区-" + movies[i].getArea() + "-电影类型-" + movies[i].getType() + "-导演-" + movies[i].getDirector() + "-主演-" + movies[i].getStarring());
                return;
            }
        }
        // 没找到！
        System.out.println("您输入的编号不存在!");
    }

    /**
     * 展示电影系统中全部的电影（名称、评分）
     */
    private void queryMoviesInfo() {
        for (int i = 0; i < movies.length; i++) {
            Movie movie = movies[i];
            System.out.println("电影名：" + movie.getTitle() + "---评分：" + movie.getScore());
        }
    }
}

3.测试类（main函数类）

java 复制代码

package com.liujintao.test;

import com.liujintao.domain.Movie;

public class MovieTest {
    public static void main(String[] args) {
        // 构造器初始数据
        Movie movie1 = new Movie(1, "东八区的先生们", "2022", 2.1, "中国大陆", "剧情 喜剧", "夏睿", "张翰 王晓晨");
        Movie movie2 = new Movie(2, "上海堡垒", "2019", 2.9, "中国大陆", "爱情 战争 科幻", "滕华涛", "鹿晗 舒淇");
        Movie movie3 = new Movie(3, "纯洁心灵·逐梦演艺圈", "2015", 2.2, "中国大陆", "剧情 喜剧", "毕志飞", "朱一文 李彦漫");
        // 将数据存到数组中
        Movie[] movies = {movie1, movie2, movie3};

        MovieService movieservice = new MovieService(movies);
        movieservice.start();

    }
}
