我有一个需要打印的数组，并且已经查看了stackoverflow，所以我知道我需要使用toString以便不只是打印哈希码，但由于某种原因，它仍在打印诸如“ music2.Music2@4162b8ce，music2.Music2@3852fdeb，music2.Music2@509c6c30”

Music2[] musiclist = new Music2[10];
musiclist[0] = new Music2("Pieces of You", "1994", "Jewel");
musiclist[1] = new Music2("Jagged Little Pill", "1995", "Alanis Morissette");
musiclist[2] = new Music2("What If It's You", "1995", "Reba McEntire");
musiclist[3] = new Music2("Misunderstood", "2001", "Pink");
musiclist[4] = new Music2("Laundry Service", "2001", "Shakira");
musiclist[5] = new Music2("Taking the Long Way", "2006", "Dixie Chicks");
musiclist[6] = new Music2("Under My Skin", "2004", "Avril Lavigne");
musiclist[7] = new Music2("Let Go", "2002", "Avril Lavigne");
musiclist[8] = new Music2("Let It Go", "2007", "Tim McGraw");
musiclist[9] = new Music2("White Flag", "2004", "Dido");

public static void printMusic(Music2[] musiclist) {
     System.out.println(Arrays.toString(musiclist));
}

这是我的数组以及我用来打印它的方法。任何帮助，将不胜感激。

最佳答案

您应该在toString()类中定义Music2方法，并以自己喜欢的方式打印它。我不知道对象中字段的确切命名方式，但是看起来像这样：

public class Music2 {
    ...

    @Override
    public String toString() {
        return this.artist + " - "+ this.title + " (" + this.year + ")";
    }
}

之后，您的printMusic方法将按预期工作。
