//this is my array.
    import javax.swing.JOptionPane;
    public class SongTestDrive2
    {
        public static void main(String[] args)
        {

            Song2[] mySong2 = new Song2[2];
            int x = 0;
            mySong2[0] = new Song2();
            mySong2[1] = new Song2();
            mySong2[0].name = "Song Title: soul to squeeze";
            mySong2[1].name = "Song Title: Slaughtered";
            mySong2[0].artist = "Artist: Red Hot Chili Peppers";
            mySong2[1].artist = "Artist: PanterA";
            mySong2[0].genre = "Genre: Funk Rock";
            mySong2[1].genre = "Genre: Groove Metal";
            mySong2[0].year = "Year: 1993";
            mySong2[1].year = "Year: 1994";
           }

    }

Answer 1

我不明白你的问题是什么，所以我只会根据你所写的内容和你似乎想做的事情来回答一些似乎相关的问题。

private String[] myMethod() {
   String[] myArr = {"1", "2", "3"};
   return myArr;
}

这就是方法返回数组的方式。

要将数组作为参数传递给方法，只需指定该方法采用数组作为参数

private void myMethod(String[] data) {
   System.out.println(data[0]);
}
