如何获取数组的子索引值

Question

我们有这样的数组

[
    [6:02:48 , 06:06:20, 2015-03-24, Tuesday, kuja], 
    [06:06:20, 06:15:25, 2015-03-24, Tuesday, rahu], 
    [06:15:25, 06:23:30, 2015-03-24, Tuesday, guru],
    [06:23:30, 06:33:05, 2015-03-24, Tuesday, shani], 
    [06:33:05, 06:41:40, 2015-03-24, Tuesday, budha], 
    [06:41:40, 06:45:12, 2015-03-24, Tuesday, kethu],
    [06:45:12, 06:55:18, 2015-03-24, Tuesday, shukra]
]

当我们打印数组upsublist.get（o）; 输出如下： [6:02:48 , 06:06:20, 2015-03-24, Tuesday, kuja]

我们只需要获取一个值，例如kuja or rahu or guru 。请告诉我。如何获取仅一个值

我们尝试像这样upsublist.get(o).get(4)我们像这样

Answer 1

如果[6:02:48 , 06:06:20, 2015-03-24, Tuesday, kuja]是一个数组，并且长度始终为5，则只需编写upsublist.get(o)[4]即可最后一个元素。 如果它是ArrayList，则可以编写upsublist.get(o).get(4) 。

如果长度不固定，则必须找到最后一个元素的索引upsublist.get(o)[upsublist.get(o).length - 1] 。
