一. 需求:使用面向对象编程,模仿电影信息的展示

分析:   

• 一部电影是一个Java对象,先设计电影类，再创建电影对象
• 三部电影对象可以采用数组封装起来
• 依次遍历数组中的每个电影对象，取出其信息并展示

// 创建电影类，用于后期创建电影对象
public class Movie {// 1.成员变量使用private修饰private String name; // 名称private double score; // 评分private String region; // 地区private String type; // 类型private String director; // 导演private String actor; // 主演// 2.提供一个无参构造器public Movie(){}// 有参构造器public Movie(String name,double score,String region,String type,String director,String actor){this.name = name;this.score = score;this.region = region;this.type = type;this.director = director;this.actor = actor;}// 3.提供成员变量对应的Setter,Getter方法public void setName(String name){this.name = name;}public String getName(){return name;}public void setScore(double score){this.score = score;}public double getScore(){return score;}public void setRegion(String region){this.region = region;}public String getRegion(){return region;}public void setType(String type){this.type = type;}public String getType(){return type;}public void setDirector(String director){this.director = director;}public String getDirector(){return director;}public void setActor(String actor){this.actor = actor;}public String getActor(){return actor;}
}

public class MovieSystem {public static void main(String[] args) {// 1.动态初始化一个电影类型的数组Movie[] movies = new Movie[3];// 2.给电影类型的数组依次录入电影信息movies[0] = new Movie("长津湖",3.5,"中国","剧情/历史/战争","陈凯歌/徐克","吴京/易烊千玺");movies[1] = new Movie("我和我的父辈",4.0,"中国大陆","剧情","吴京/章子怡","徐峥/沈腾");movies[2] = new Movie("五个扑水的少年",3.0,"中国大陆","剧情/戏剧/运动","宋灏霖","李云来/王川");// 3.遍历数组中的每个电影对象,取出其信息并展示for(int i = 0;i < movies.length;i++){Movie movie = movies[i];System.out.println("电影名:" + movie.getName());System.out.println("评分:" + movie.getScore());System.out.println("地区:" + movie.getRegion());System.out.println("类型:" + movie.getType());System.out.println("导演:" + movie.getDirector());System.out.println("主演:" + movie.getActor());System.out.println("----------------------------");}}
}
