是否可以使用 String 作为变量名.. 就像在这个例子中一样 -
String musicPlaying = "music2";
Music music1 = new Music("blaalla");
Music music2 = new Music("blalala");
Music music3 = new Music("balaada");
if(!musicPlaying.stillPlaying) { // As you can see i am using string as a variable name.
changeMusic();
}
最佳答案
您可以做的是将这些值关联(映射)到 Music 对象。这是示例:
Map<String, Music> musics = new HashMap<>();
String musicPlaying = "music2";
musics.put("music1", new Music("blaalla"));
musics.put("music2", new Music("blalala"));
musics.put("music3", new Music("balaada"));
if(!musics.get(musicPlaying).stillPlaying) { // As you can see i am using string as a variable name.
changeMusic();
}
