如何模仿Java中PHP的关联数组排序？

Question

I have a PHP code:

$array['cows'] = 4;
$array['horses'] = 7;
$array['cats'] = 9;
$array['dogs'] = 2;

arsort($array);

How to do it in Java?

Sorted (from max) output of 'print_r($array);' is:

Array
(
    [cats] => 9
    [horses] => 7
    [cows] => 4
    [dogs] => 2
)

Answer 1

For PHP associative array you should use Map type in Java (HashMap or TreeMap). Sorting of this types described in this article
