How to search and sort in J2me (ascending or descending)

Question

I am wondering about how to search in J2ME. I have been searching in the internet, so many result show to me, and I see in Java2s.com I got a result use RecordFilter and matches method for search in record store.

But my problem is, when I need to pass 2 or more parameters into it. How can result matches with these parameter?

And how to sort descending or ascending like bubble sort?

Answer 1

Concatenate your searches into a single String variable. Separate each of them with ; for example. In the code of the matches method explode the String to get each search criteria. To make the filter in effect create an instance of SearchFilter and call the matches method with the concantenated String as its param. For the sort implement the RecordComparator interface ; implement the compare method to build your sort criteria. Make a google search about j2me+recordcomparator to see examples about how to make sorts.

EDIT :

In the code of the matches method explode the String param obtained from the byte[] param. Treat each String exploded to make the criteria. As I understand you want to pass two string as a search criteria when you wrote :

SearchFilter search = new SearchFilter(txtSearch.getString(), strType);

So in the constructor there should be two params !!!

When you want to make the matching then call

if searchFilter.matches((search1+";"+sType).getBytes())

Then explode the candidate param into two String when you code the matches method.
