我正在写这篇文章吗？ [noob]

Question

private final int NUM_SOUND_FILES = 4; 
private Random rnd = new Random(4); 
private int mfile[] = new mfile[NUM_SOUND_FILES]; //the second mfile 
                 //reports error everytime 
mfile[0] = R.raw.sound1; 
mfile[1] = R.raw.sound2; 
mfile[2] = R.raw.sound3; 
mfile[3] = R.raw.sound4; 

int sndToPlay = rnd.nextInt(NUM_SOUND_FILES); 

无论我如何编写，我都会收到语法错误。当我获得正确的语法时，它会强制关闭。下面是与所谓的“正确”的语法，但forcecloses：

private final int NUM_SOUND_FILES = 4; 
private Random rnd = new Random(4); 
private int mfile[] = new int[NUM_SOUND_FILES];{ 
mfile[0] = R.raw.sound1; 
mfile[1] = R.raw.sound2; 
mfile[2] = R.raw.sound3; 
mfile[3] = R.raw.sound4;} 

Answer 1

我不是Android开发人员，但对行数组声明3不正确的看向我，通常其类型为int数组这将是声明如下：

private int[] mfile = new int[NUM_SOUND_FILES];
