如何实现一个函数来计算一个艺术家在Java中有多少首歌曲

public class Artist {
    private String name;
    private int songCount;

    public Artist(String name, int songCount) {
        this.name = name;
        this.songCount = songCount;
    }

    // Getters and setters
    // ...
}

public int calculateSongCount(Artist artist) {
    return artist.getSongCount();
}

public static void main(String[] args) {
    Artist artist = new Artist("艺术家姓名", 10);
    int songCount = calculateSongCount(artist);
    System.out.println("艺术家在Java中有 " + songCount + " 首歌曲。");
}
