java方法对象案例

完成电影信息展示功能；根据电影id查询该电影的详细

主方法： 

package Y;
import java.util.Scanner;
public class 模仿电影系统main {
//目标：完成电影信息展示功能；根据电影id查询该电影的详细
//电影数据
    //  1,"水门桥",38.9,9.8,"徐克","吴京","12万人想看"
    // 2,"出学吧",39,7.8,"唐晓白","田雨","3.5万人想看"
    // 3,"月球陨落",42,7.9,"罗兰","贝瑞","17.9万人想看"
    // 4,"一点到家",35,8.7,"许宏宇","刘昊然","10.8万人想看"
    public static void main(String[] args) {
    //1、设计一个电影类
    //2、设计一个电影的操作类
    //3、定义一个movie01类型的数组接受电影信息；定义电影类型的数组
        movie01 moove[] = new movie01[4];//此时是设置了四个电影
        movie01 m1 = new movie01( 1,"水门桥",38.9,9.8,"徐克","吴京","12万人想看");
        movie01 m2 = new movie01( 2,"出学吧",39,7.8,"唐晓白","田雨","3.5万人想看");
        movie01 m3 = new movie01( 3,"月球陨落",42,7.9,"罗兰","贝瑞","17.9万人想看");
        movie01 m4= new movie01( 4,"一点到家",35,8.7,"许宏宇","刘昊然","10.8万人想看");
    //4、把对象存入到数组moove当中
       moove[0]=m1;
       moove[1]=m2;
       moove[2]=m3;
       moove[3]=m4;

       moove[1]=new 模仿电影系统方法01( 2,"出学吧",39,7.8,"唐晓白","田雨","3.5万人想看");
       moove[2]=new 模仿电影系统方法01( 3,"月球陨落",42,7.9,"罗兰","贝瑞","17.9万人想看");

       */
        movie02 y = new movie02(moove);
       tuichu: while (true){//设置一个死循环，持续打印如下代码
           System.out.println("=====电影信息系统=====");
           System.out.println("1.展示系统中的全部电影信息");
           System.out.println("2.展示对应编号的电影详细");
           System.out.println("3.退出");
           System.out.println("请输入您的操作指令");
           Scanner Y = new Scanner(System.in);
           int select = Y.nextInt();
           if (select == 1) {//若输入的是1的话进入（模拟电影系统方法02）
               y.printAll();
//               break;
           }else if (select == 2) {
               System.out.println("请输入要查询电影的编号");
               int id = Y.nextInt();
               y.printChoose(id);
//               break;
           }else if (select == 3){
               break ;

               System.out.println("您输入的指令有问题！请重新输入");
           }
       }
    }
}

存数据类：

package Y;
//此处是设置了一个电影类
public class movie01 {
    private int id;//定义电影的编号
    private String name;//定义电影的名字
    private double price;//定义电影的价格
    private double score;//定义电影的评分
    private String daoyan;//定义导演信息
    private String actor;//定义演员信息
    private String info;//定义其他信息
//定义一个有参构造器接受数据
    public movie01(int id, String name, double price, double score, String daoyan, String actor, String info) {
        this.id = id;
        this.name = name;
        this.price = price;
        this.score = score;
        this.daoyan = daoyan;
        this.actor = actor;
        this.info = info;
    }
    //无参构造器
    public movie01(){}
    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 getDaoyan() {
        return daoyan;
    }

    public void setDaoyan(String daoyan) {
        this.daoyan = daoyan;
    }

    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;
    }
}

进行数据操作的类：

package Y;
//此处是设计了一个电影的操作类
public class movie02 {
//1、定义电影数组接受多部电影
    private movie01 movies[];//moives其实就相当于一个一个的电影对象
 //2、定义一个有参构造器接受这个多部电影
    public movie02(movie01 movies[]){
        this.movies = movies;
    }
//3、展示所有电影
    public void printAll(){
        for(int i=0;i<movies.length;i++){
            System.out.println("-----系统全部电影信息如下-----");
            System.out.println("编号："+movies[i].getId());
            System.out.println("名称："+movies[i].getName());
            System.out.println("价格："+movies[i].getPrice());
            System.out.println("--------------------");
        }
    }
    public void printChoose(int id) {
        for(int i=0;i<movies.length;i++){
            if(movies[i].getId() == id){
                System.out.println("-----编号为"+(i+1)+"的电影具体信息如下-----");
                System.out.println("编号："+movies[i].getPrice());
                System.out.println("名称："+movies[i].getName());
                System.out.println("价格："+movies[i].getPrice());
                System.out.println("评分："+movies[i].getScore());
                System.out.println("导演信息："+movies[i].getDaoyan());
                System.out.println("演员信息："+movies[i].getActor());
                System.out.println("其他信息："+movies[i].getInfo());
                System.out.println("--------------------");
                return;//表示已经找到了，结束了
            }
        }
            System.out.println("没有该电影信息~~");//因为上面return跳出了方法，这条输出则不执行

    }
