How can I sort an ArrayList of type: List<Map<String, Object>> according to a property of that list, when I have the properties in the right order as a String?

e.g. I have a big list containing of ids and names. And I have the ids in the wanted order in a string. How can I order the list according to the string?

You can refer the following StackOverflow post.

In summary, you could create a Comparator for the corresponding class; or implement the Comparable interface.

The word duplicate in there indicates that well, duplicates are around. Putting up an answer that only links to another answer, sorry, that is, well, lame?!
