使用BufferedReader获取Java上的数据

Question

我是java新手，需要帮助。 我正在用Java为一个大学活动制作一个Mp3播放器。首先，我需要获得所有艺术家的信息。所以我创建了艺术家课程：

public class Artist {

    int id;
    String Artist_name, country;


            //This is the contructor
    Artist(int id, String Artist_name, String country){
    this.id = id;
    this.Artist_name = Artist_name;
    this.country = country;
    }


    public int getId() {
        return id;
    }




    public void setId(int id) {
        this.id = id;
    }




    public String getArtist_name() {
        return Artist_name;
    }




    public void setArtist_name(String Artist_name) {
        Artist_name = Artist_name;
    }




    public String getCountry() {
        return country;
    }



    public void setCountry(String country) {
        this.country = country;
    }



    //This is the toString method. I must use it for this activity. It just links everything.
    public String toString(){   
        return "ID: " + id + "\n" + "Name: " + artist_name + "\n" + "Country: " + country;
    }

好的，现在我只需要一个ArtistTest类来测试一切。前两个实例必须是硬代码插入，然后第三个实例是使用BufferedReader的常规用户插入。这就是我的问题，我该怎么做？然后，我如何使用toString方法来打印这三位艺术家？ 这是我到目前为止编写的代码（不完整，可能是错误的）

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ArtistTest {

public static void main(String[] args) throws IOException{

    Artist band1, band2;

            //Just hardcode.
    try{
    band1 = new Artist(1,"The Beatles","England");
    band2 = new Artist(2,"The Rolling Stones","England");
    }

    catch(Exception e){
    System.out.println("Error");
    }

    //The problem...
    BufferedReader band3= new BufferedReader(new InputStreamReader(System.in));

    try{
        System.out.print("ID:");
                    ...
        System.out.print("Artist Name:");
                   ...
        System.out.print("Country:");
                   ...
}

    catch(IOException e){
        System.out.println("Erro");
    }

    toString(...)
}

}

谢谢你的建议
