类返回数组 [英] Class that returns arrays

问题描述

林非常java的非常新。我试着去做出返回关于几部电影（所有这些信息都存储在阵列）一些信息的类。林卡住，不知道该怎么做。这里是我的code

Im very very new to java. Im trying to make a class that returns some info about a few movies (all this info is stored in array). Im stuck and dont know what to do. Here is my code

电影类：

public class Movie {

    String[] Director;
    String[] Name;
    String[] realeaseDate;
    String[] lastShow;


    public Movie()
    {
        String[] Director={"George Romero","Woody Allen","Steven Speilberg","James Cameron"};
        String[] Name={"Diary of the Dead","Midnight in Paris","War of the Worlds","Terminator 2 - Judgment Day"};
        String[] realeaseDate={"Dec 31 1999","Dec 28 1999","Dec 15 1999","Dec 10 1999"};
        String[] lastShow={"Jan 13 2000","Jan 29 2000","Jan 23 2000","Jan 15 2000"};

    }

    public String getDirector()
    {
        return Director;
    }

    public String getName()
    {
        return Name;
    }

    public String getRealease()
    {
        return realeaseDate;
    }

    public String getLast()
    {
        return lastShow;
    }

}

现在，这里是我公司主营：

Now here is my Main:

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub


        String newLine = System.getProperty("line.separator");
        Movie movies = new Movie();

        System.out.println("Avaliable movies"+newLine);

        System.out.println("Director: "+ movies.getDirector()+newLine+"Name :"+ movies.getName()+ newLine + "Realease Date: "+ movies.getRealease()+newLine+"Last Show :"+ movies.getLast()+newLine);

    }

}

我想要的结果是这样的：

I want the result to be like:

所有可用的电影

乔治...
日记...
十二月..
januar ...

George... Diary of... dec.. januar...

史蒂芬..
sdafsda ...
十二月...
扬..

Steven.. sdafsda... Dec... Jan..

。

推荐答案

既然你是新来的Java我也建议治疗电影类作为一个单一的对象（而不是电影中的数组），然后将值存储在一个列表电影的对象。这样，每个影片对象包含只是一部电影的信息。这将是更加面向对象的方法

Since you are new to java I would also recommend treating the movie class as a single object(not an array of movies) and then store the values in a list of movie objects. This way each movie object contains just the information about a single movie. This would be the more object oriented approach

public class Movie {

    String Director;
    String Name;
    String releaseDate;
    String lastShow;


    public Movie(String director, String name, String release, String lastShow)
    {
        this.Director = director;
        this.Name = name;
        this.releaseDate = release;
        this.lastShow = lastShow;
    }

    public String getDirector()
    {
        return Director;
    }

    public String getName()
    {
        return Name;
    }

    public String getRelease()
    {
        return releaseDate;
    }

    public String getLast()
    {
        return lastShow;
    }

}

然后你的主文件可能如下所示：

And then your main file might look like the following:

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub


        String newLine = System.getProperty("line.separator");
        Movie firstMovie= new Movie("George Romero","Diary of the Dead", "Dec 31 1999","Jan 13 2000" );
        Movie secondMovie = new Movie("test", "name", "date", "date");
        ArrayList<Movie> movies = new ArrayList<Movie>();
        //add movies to list

        System.out.println("Avaliable movies"+newLine);

        //loop through each movie in movies

        //print information about each movie

    }

}

我会离开的实现了的休息，锻炼你，但这个应该指向你在正确的方向。

I will leave the rest of the implementation up to an exercise for you, but this should point you in the right direction.
