一个`merge()方法搞定,代码如下: //Apache Commons result = MapUtils.merge(map1, map2); assertEquals(expected, result); 7 总结 本文分别列举了数组、List、Set和Map的合并的多种方法,虽然代码简单,理解也容易,但这些方法应该熟练掌握。可以收藏一下,必要的时间查一查。 欢迎关注公众号<南瓜慢说>,将持续...

The included source code also features another fork/join example based on the merge-sort algorithm over arrays of integers. This is interesting because it is implemented using RecursiveAction, the fork/join task that does not yield values on join()method invocations. Instead, tasks share mutable ...
