Thanks a lot for the information. Could you be more specific? Say for example, I'd like to sort by age. How would you proceed?

Question
How to sort arrays of arbitrary objects?
I'm trying to write a sort method in java that can sort 1d arrays of arbitrary objects. Even though the java library contains such a capability, I'd like to use interface to accomplish the same thing. I did quite some research but figured there's no way to do so without using the Comparable or Comparator interfaces. The concept of function pointers comes to mind but Java does not support them. Could you help me out? Any examples would help. Thanks.
I found the following very helpful:

Initially take all the objects into an Arrary or vector. Traverse through each and every object and insert them into Linked List Object based on your sort criteria. If sort criteria is Age then compare age of each object from Array List with each object in LinkedListand insert your object in appropriate position of Linked List.
You can use ArraryList object to insert in the middle of the arry list instead of using Linked List.

"sort 1d arrays of arbitrary objects". The issue is that you need to specify the field on which you need to sort the object. For eg a class Person - maybe contain fields first name, last name, age etc. Which field will you sort by?
Brute force can always be applied, even though not recommended.
