了解三维数组

顺序无关紧要，实际上前一种形式更易于阅读：

final const int RED = 0;final const int GREEN = 1;final const int BLUE = 2;int[][][] colorImage = new int[numRows][numColumns][3];//...int x = getSomeX();int y = getSomeY();int redComponent = colorImage[x][y][RED];int greenComponent = colorImage[x][y][GREEN];int blueComponent = colorImage[x][y][BLUE];
