android编程
数组:
static final int g[][]=new int[][]{
{3,16,29,42},
{4,17,30,43},
{5,18,31,44},
{6,19,32,45},
{7,20,33,46},
{8,21,34,47},
{9,22,35,48},
{10,23,36,49},
{11,24,37,50},
{12,25,38,51},
{13,26,39,52},
{14,27,40,53},
{15,28,41,54},
};
int a = new Random().nextInt(g.length * g[0].length);
下面的随机数的范围g.length和g[0].length分别是什么意思

这是Java基础,g.length是你整个 二维数组中 一维数组的个数. g[0].length 是 {3,16,29,42}这个里里面元素的个数.也就是4.
